                                PROXY STATEMENT
 
     YOUR VOTE IS VERY IMPORTANT. For this reason, the Board of Directors is
soliciting Proxies to be used at the 1999 Annual Meeting. This Proxy Statement
is being sent to you in connection with this request and has been prepared for
the Board by our management. "We", "our", "Smith" and the "Company" each refers
to Smith International, Inc. This Proxy Statement is first being sent to our
stockholders on or about March 26, 1999. IT IS IMPORTANT THAT YOUR SHARES BE
REPRESENTED AT THIS MEETING. EVEN IF YOU PLAN TO ATTEND THE MEETING, PLEASE VOTE
(1) BY COMPLETING, SIGNING, DATING AND MAILING THE PROXY CARD IN THE ENCLOSED
POSTAGE PRE-PAID ENVELOPE, OR (2) BY CALLING THE TOLL-FREE TELEPHONE NUMBER
LISTED ON THE PROXY CARD, OR (3) VIA THE INTERNET AS INDICATED ON THE PROXY
CARD.
 
                        GENERAL INFORMATION ABOUT VOTING
 
WHO CAN VOTE.
 
     You are entitled to vote your common stock if our records show that you
held your shares as of March 3, 1999. At the close of business on March 3, 1999,
a total of 48,809,056 shares of common stock ("Common Stock") were outstanding
and entitled to vote. Each share of Common Stock has one vote. The enclosed
proxy card shows the number of shares which you are entitled to vote.
 
HOW YOU CAN VOTE.
 
     If you return your signed proxy card to us, or if you vote by internet or
by telephone before the Annual Meeting, we will vote your shares as you direct.
You can specify on your proxy whether your shares should be voted for all, some,
or none of the nominees for director. You can also specify whether you approve,
disapprove, or abstain from both proposals. If your Common Stock is held by a
broker, bank or other nominee, you will receive instructions from them which you
must follow in order to have your shares voted. If the meeting is adjourned,
your Common Stock may be voted by the Proxies on the new meeting date as well,
unless you have revoked your proxy instructions.
 
     IF YOU DO NOT SPECIFY ON YOUR PROXY CARD HOW YOU WANT TO VOTE YOUR SHARES,
WE WILL VOTE THEM "FOR" THE ELECTION OF ALL NOMINEES FOR DIRECTORS AS SET FORTH
UNDER "ELECTION OF DIRECTORS" BELOW; AND "FOR" PROPOSAL 2.
 
HOW YOU MAY REVOKE YOUR PROXY INSTRUCTIONS.
 
     You can revoke your proxy at any time before it is exercised in any of four
ways:
 
          (1) by submitting written notice of revocation to the Secretary;
 
          (2) by submitting another proxy that is properly signed and later
     dated; or
 
          (3) by submitting another proxy via the internet or by telephone on a
     date after the date of your last proxy; or
 
          (4) by voting in person at the meeting.
 
NUMBER OF VOTES REQUIRED.
 
     Directors must be elected by a plurality of the votes cast at the meeting.
This means that the three nominees receiving the greatest number of votes will
be elected. A majority of the shares represented at the
 
                                        1
<PAGE>   5
 
meeting are required to approve each proposal. The Annual Meeting will be held
if a majority of the outstanding Common Stock entitled to vote is represented at
the meeting. If you have returned valid proxy instructions or attend the meeting
in person, your Common Stock will be counted for the purpose of determining
whether there is a quorum, even if you wish to abstain from voting on some or
all matters introduced to the meeting. "Broker non-votes" also count for quorum
purposes. If you hold your Common Stock through a broker, bank or other nominee,
generally the nominee may only vote the Common Stock which it holds for you in
accordance with your instructions. However, if it has not received your
instructions within ten days of the meeting, the nominee may vote on matters
which the New York Stock Exchange determines to be routine. If a nominee cannot
vote on a particular matter because it is not routine, there is a "broker
non-vote" on that matter. We do not count broker non-votes as votes for or
against any proposal; however, abstentions are voted against a proposal.
 
OTHER MATTERS TO BE ACTED UPON AT THE MEETING.
 
     We do not know of any other matters to be presented or acted upon at the
meeting, other than those mentioned in this document. If any other matter is
presented at the meeting on which a vote may properly be taken, your signed
proxy card gives authority to Doug Rock and Neal S. Sutton to vote on such
matters.
 
COST OF THIS PROXY SOLICITATION.
 
     We will pay the cost of this proxy solicitation. In addition to soliciting
proxies by mail, some of our employees may solicit stockholders for the same
type of proxy, personally and by telephone. None of these employees will receive
any additional or special compensation for doing this. We have retained Morrow &
Co. to assist in the solicitation of proxies for a fee of $6,500, plus
reasonable out-of-pocket costs and expenses. We will, upon request, reimburse
brokers, banks and other nominees for their expenses in sending proxy material
to their principals and obtaining their proxies.
 
                       PROPOSAL 1: ELECTION OF DIRECTORS
 
     At the 1999 Annual Meeting, stockholders will elect three persons as Class
I directors to hold office until the 2002 Annual Meeting or until they are
succeeded by other qualified directors who have been elected. The nominees are
G. Clyde Buck, Loren K. Carroll and Wallace S. Wilson.
 
     Directors must be elected by a plurality of the votes cast at the meeting.
This means that the three nominees receiving the greatest number of votes will
be elected. Votes withheld for any Director will not be counted.
 
     We will vote your shares as you specify on your proxy card. If you properly
execute and return your proxy card (in paper form, electronically via the
internet or by telephone), but don't specify how you want your shares voted, we
will vote them for the election of all the nominees listed below. If unforeseen
circumstances (such as death or disability) make it necessary for the Board of
Directors to substitute another person for any of the nominees, and you have
either voted for the substituted nominee or not specified your vote, we will
vote your shares for that other person.

INFORMATION ABOUT THE BOARD OF DIRECTORS AND ITS COMMITTEES
 
     THE BOARD. During 1998, the Board of Directors held nine meetings. All
directors attended at least 75% of the meetings of the Board of Directors and of
all committees on which they served.
 
     COMMITTEES OF THE BOARD.
 
     The Company has an Audit Committee and its members are Messrs. Bailar,
Gibbs and Neely. The Audit Committee reviews Smith's auditing, accounting,
financial reporting and internal control functions. This committee also
recommends the firm that Smith should retain as its independent accountant. All
members are non-employee directors. During 1998, the Audit Committee held two
meetings.
 
     The Company has a Compensation and Benefits Committee, and its members are
Messrs. Gibbs, Buck and Neely. The Compensation and Benefits Committee reviews
Smith's executive compensation and employee benefit plans and programs,
including their establishment, modification and administration. It also
administers the Company's stock option plan. During 1998, this committee held
two meetings. The Executive Compensation Subcommittee of this committee,
comprised of Messrs. Gibbs and Buck, held two meetings during 1998.
 
     The Company has an Executive Committee and its members are Messrs. Neely,
Carroll, Gibbs and Rock. The Executive Committee has limited power to act on
behalf of the Board whenever the Board is not in session. This Committee meets
only as needed and did not meet in 1998.
 
     The Board of Directors does not have a Nominating Committee.
 
     DIRECTORS' COMPENSATION. Employee Directors receive no additional
compensation other than their normal salary for serving on the Board or its
Committees. Non-employee Directors receive $20,000 annually and $1,500 for each
meeting attended. In addition, they are paid $3,000 for chairing a committee and
paid $1,250 for each committee meeting attended. Non-employee Directors also
receive an annual grant of 200 shares of Common Stock.
 
     NON-EMPLOYEE DIRECTOR PROGRAMS. The Company terminated its Directors'
Retirement Plan in 1998. The Company has issued each of the non-employee
directors restricted stock grants to fund the actuarial value of their accrued
benefits under the retirement plan. These grants will "cliff-vest" upon
retirement after ten years of service as a director. This means the grants will
all vest at once upon retirement after ten years of service.
 
                             EXECUTIVE COMPENSATION
 
      COMPENSATION AND BENEFITS COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
COMPENSATION POLICIES
 
     Smith's executive compensation program is designed to help the Company
attract, motivate and retain the executive resources that the Company needs in
order to maximize its return to stockholders. The objective of the Company's
compensation program for key management positions is to provide compensation
packages that are consistent with competitive market norms for companies similar
in size, activity and complexity to the Company.
 
     The Compensation and Benefits Committee (the "Committee"), which consists
solely of non-employee Directors, administers the executive compensation
programs of the Company and determines the compensation of senior management. An
independent compensation consultant, PricewaterhouseCoopers, advises the
Committee on all compensation matters.
 
     The Company's executive compensation program is structured and implemented
to provide competitive compensation opportunities and various incentive award
payments based on Company and individual performance, as well as to link
compensation to financial targets which affect short and long term share price
performance. The Committee administers all of the Company's executive
compensation programs, including
 
                                        6
<PAGE>   10
 
the design of the programs and the measurement of their effectiveness. The
Committee also reviews and approves all salary arrangements and other payments
to executives, evaluates their performance and considers other related matters.
 
TAX CONSIDERATIONS
 
     The Internal Revenue Code limits the allowable tax deduction that may be
taken by the Company for compensation paid to the Chief Executive Officer and
the four other highest paid executive officers named in the Summary Compensation
Table. The limit is $1 million per executive per year, but compensation payable
solely upon the attainment of performance goals is excluded from the limitation.
The Committee has established an Executive Compensation Subcommittee to review
and establish compensation for any executive officer whose compensation might
exceed $1 million in any year. The Subcommittee consists of two members of the
Committee, Messrs. Gibbs and Buck, who are independent directors as defined in
the Internal Revenue Code and its regulations. The Subcommittee and Committee
will continue to analyze its executive compensation practices and plans on an
ongoing basis with respect to Section 162(m) of the Internal Revenue Code. Where
it deems advisable, the Committee will take appropriate action to maintain the
tax deductibility of its executive compensation.
 
TYPES OF COMPENSATION
 
     There are two main types of compensation:
 
          (1) Annual Compensation. This includes base salary and annual
     incentives (bonuses). Smith awards bonuses only when a year's financial
     performance meet a certain level required under the annual incentive plan.
 
          (2) Long-Term Compensation. This includes stock options and other
     long-term incentive awards based on Common Stock. The value of these awards
     depends upon Company performance and future stock value.
 
FACTORS CONSIDERED IN DETERMINING COMPENSATION
 
     The Committee wants the compensation of Smith executives to be competitive
in the worldwide energy industry. The Committee estimates an executive's
competitive level of total compensation based on information from a variety of
sources, including proxy statements, special surveys and its compensation
consultant. The companies that are part of the Peer Group described in the
performance graph are some of the companies used by the Committee in
establishing both base salary and performance-based targeted incentive
compensation. The sources used by the Committee are larger than the Peer Group,
but are all in the energy industry. The Committee then compares the industry
information with the Peer Group and with the Company's compensation levels to
determine both base salary and incentive compensation.
 
  Annual Compensation
 
     Annual compensation for Smith executives includes salary and bonus. This is
similar to the compensation programs of most leading companies.
 
     The Committee annually reviews each executive's base salary. The Committee
aims to pay salaries at the median of the range of compensation paid by similar
companies. The Committee also looks at the specific job duties, the person's
achievements and other criteria. Increases in base salary are primarily the
result of individual performance, which includes meeting specific goals
established by the Committee. The criteria used in evaluating individual
performance varies depending on the executive's function, but generally include
leadership inside and outside the Company; advancing the Company's interest with
customers, vendors and in other business relationships; product quality and
development; and advancement in skills and responsibility. In 1998, seven
executive officers received merit increases.
 
                                        7
<PAGE>   11
 
  Annual Incentive Compensation.
 
     The annual incentive plan promotes the Company's pay-for-performance
philosophy by providing executives with direct financial incentives in the form
of cash awards that are paid based on the achievement of performance objectives
established for the fiscal year. Each year the Committee sets corporate goals
based upon financial objectives deemed appropriate by the Committee. These
objectives may include earnings per share, profit after tax, return on assets,
return on net capital employed, or other financial objectives for the year.
Where executives have strategic business unit responsibilities, their goals are
based on financial performance measures supporting that business unit's
performance. No bonus is paid unless certain threshold Company performance
levels set by the Committee are reached.
 
     Each year the Committee sets targets for each executive relating to annual
incentive compensation. The target incentive awards for 1998 for eligible
Company executives were based on various company, business unit and individual
performance measures. The Committee does not use a specific formula for weighing
individual performance. Instead, individuals are assessed based upon how they
contributed to the Company's business success in his or her area of
responsibility. Awards were made in 1998 under the Annual Incentive Plan for
fiscal year 1997 to eligible executives.
 
  Stock Option Program
 
     The Committee strongly believes that the grant of significant annual equity
awards further links the interests of senior management and Smith's
stockholders. Each year, the Committee determines the total amount of options to
be made available to the Company's executives. These amounts vary each year and
are based upon what the Committee believes is appropriate. The Committee
considers an executive's total compensation package, including the amount of
stock options previously awarded. Other important factors are the desire to
create stockholder value, encourage equity ownership, provide an appropriate
link to stockholder interests and provide long-term incentive award
opportunities in the same range as similar companies in the Company's industry.
 
  Chief Executive Officer Compensation
 
     As described above, the Committee determines pay levels for all executives,
including the Chief Executive Officer, considering both a pay-for-performance
philosophy and market rates of compensation for similar positions. A significant
portion of compensation for the Executive Officer is based upon the Company's
performance. Specific actions taken by the Committee regarding Mr. Rock's
compensation are summarized below.
 
     Base Salary -- The base salary for Mr. Rock was reviewed at the December
1997 meeting of the Committee and increased to $650,000. In setting Mr. Rock's
base salary for fiscal year 1998, the Committee reviewed the recommendations by
the independent consultant, PricewaterhouseCoopers, market comparisons as well
as the Company's positive financial performance during fiscal year 1997 with
respect to revenue growth, expense control, net income and earnings per share.
 
     Annual Incentive -- Predetermined bonus objectives set by the Committee
were achieved by each of the named executive officers based on the Company's
fiscal year 1997 financial performance. For fiscal year 1997, Mr. Rock earned an
annual bonus in the amount of $550,000 which was paid in 1998.
 
     Stock Options -- Non-qualified stock options to purchase 140,000 shares
were granted to Mr. Rock on December 1, 1998 at the recommendation of the
Committee. The award of stock options to Mr. Rock was approximately 16% of the
total stock options granted to all employees of the Company in 1998. The options
were granted at 100% of fair market value on the date of grant. The performance
sensitivity of the grant is built into the option concept, since the options
produce no gain unless the Company's share price rises over the initial grant
price.

SUMMARY
 
     The Committee believes that the compensation program for the executives of
the Company is comparable with compensation programs provided by companies
within the energy industry and serves the best interests of Smith's
stockholders. The Committee also believes that annual performance pay is
appropriately linked to individual performance, annual financial performance of
the Company and stockholder value.

                COMPARISON OF FIVE-YEAR CUMULATIVE TOTAL RETURN
 
     Below is a line graph comparing the cumulative total stockholder return of
Smith's Common Stock against the cumulative total return of the S&P 500 Index
and our Peer Group for each of the five years in the period starting December
31, 1993 and ending December 31, 1998. Our Peer Group consists of the following
companies in the same general line of business as the Company: Baker Hughes,
Inc., BJ Services Company, Daniel Industries, Inc., Dresser Industries, Inc.
(acquired by Halliburton Company in September 1998), Weatherford International
Inc., Halliburton Company and Tuboscope, Inc.
 
     The results are based on an assumed $100 investment on December 31, 1993
and reinvestment of dividends. For each index, total return is based on market
capitalization of its components.

(1) Options were granted to the Named Officers on December 1, 1998 at an
    exercise price of $23.56. The exercise price per share is equal to the
    closing price of the Common Stock on the New York Stock Exchange Composite
    Tape on the date of grant. Options granted vest at a rate of 25% per year
    and will not begin to become exercisable until December 1, 1999. If a change
    of control occurs, all outstanding options would become exercisable
    immediately.
 
(2) Present value was calculated using the Black-Scholes option pricing model.
    Use of this model should not be viewed in any way as a forecast of the
    future performance of the Company's Common Stock, which will be determined
    by future events and unknown factors. The estimated values under the
    Black-Scholes model are based upon certain assumptions as to variables such
    as interest rate and stock price volatility.

                  RETIREMENT BENEFITS AND EMPLOYMENT CONTRACTS
 
PENSION PLAN
 
     Smith International, Inc. Restated Pension Plan. The Company has a defined
benefit pension plan (the "Restated Pension Plan") which is currently frozen.
The benefit accruals were frozen effective March 1, 1987, and the amount of the
pension benefit was fixed for all eligible employees based only upon benefit
accruals from September 1, 1985 to March 1, 1987. Any benefits under the
Restated Pension Plan are offset by benefits paid under a previous pension plan
of the Company.
 
     The following table illustrates the estimated annual retirement benefit
payable as a life annuity under the Restated Pension Plan and the Supplemental
Pension Plan (which is discussed below) to any employee retiring at normal
retirement age in various compensation levels and certain years-of-service
classifications.

     Since benefit accruals under the Company's Restated Pension Plan have been
frozen since March 1, 1987, the years of service for the Named Officers is only
the period from September 1, 1985 to March 1, 1987. The annual pension benefit
that would be payable at age 65 under the Restated Pension Plan to the Named
Officers are as follows: Mr. Rock: $8,150; Mr. Carroll: $4,282; Mr. Sutton:
$-0-; Mr. Heppenstall: $1,631; and Mr. Kennedy: -0-.
 
     Smith International, Inc. Supplemental Pension Plan. Supplemental
retirement benefits are provided to all of the executive officers and certain
other participants under the Smith International, Inc. Supplemental Pension Plan
(the "Supplemental Pension Plan"). This plan allows participants to retire at
age 60. The participants receive an unfunded annual benefit at retirement equal
to that which they would have been paid had the participant remained employed
until age 65. Participants who reach age 55 while actively employed by the
Company and who accrue five years of service with the Company are vested in
their benefit. If a participant dies after reaching age 55, his or her spouse is
entitled to a survivor's benefit.
 
SMITH INTERNATIONAL, INC. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN ("SERP")
 
     The Company adopted the SERP effective October 1, 1993. It is a
non-qualified, deferred compensation plan covering all of the executive officers
and certain other participants. The primary purpose of the SERP is to provide
executives who are affected by the Internal Revenue Code (the "Code")
limitations governing the Company's 40l(k) Retirement Plan (the "40l(k) Plan")
with the opportunity to defer a portion of their current compensation.
Distributions may generally be made following a participant's termination of
employment. A participant in the SERP may defer up to 50% of his or her salary
for a plan year ending December 31. A participant may also defer up to 100% of
any Annual Incentive bonus awarded during the plan year. The Company may also
make contributions to the SERP on behalf of its participants.
 
     Age-Weighted Contributions. Effective as of the last day of each quarter
during the year, a contribution may be allocated under the SERP based on the
participant's age-weighted contribution percentage
 
                                       13
<PAGE>   17
 
("AWCP") ranging from 2 to 6%. The difference between a participant's (i) "Total
401(k) Compensation" and his or her (ii) "Net 401(k) Compensation" is multiplied
by the AWCP to compute the age-weighted contribution for the year. "Total 401(k)
Compensation" generally means the total of all cash amounts paid by the Company
to a participant, including deferred amounts. "Net 401(k) Compensation"
generally means Total 401(k) Compensation less participant contributions to the
SERP, but not to exceed $160,000 for any year. Effective January 1, 1995, the
SERP was amended to fix the AWCP for the executive officers at 6%.
 
     Matching Contributions. The SERP contains matching provisions which mirror
the matching formulas in effect for the 401(k) Plan for a given plan year, but
without regard to certain Code limits applicable to the 401(k) Plan. Matching
contributions for a plan year in both the SERP and 401(k) combined cannot exceed
6% of a participant's Total 401(k) Compensation net of any incentive bonus.
Effective January 1, 1995, the SERP was amended so that executive officers will
receive combined matching contributions up to 6% of their Total 401(k)
Compensation.
 
     Discretionary Profit Sharing Contributions. The Compensation Committee of
the Board may, in its discretion, determine the amount of any Company profit
sharing contribution for a plan year and how such amount is to be allocated
among the SERP participants.
 
EMPLOYMENT AGREEMENTS
 
     The Company has employment agreements with three senior officers, including
Messrs. Rock and Sutton. The agreements with Messrs. Rock, Sutton and one senior
officer have an initial term of three years and are automatically extended for
an additional year at each anniversary date. The employment agreements contain
the employee's salary and other conditions of employment and entitle the
employee to participate in the Company's bonus program and other benefit
programs.
 
     The employment agreements were amended to become operative upon a "change
of control" of Smith (as defined in the amendment) and to provide for the
continuation of salary and benefits. If the employee is terminated by the
Company (other than for cause), or if the employee elects to terminate his
employment, the employee is entitled to receive a lump sum payment in cash equal
to the sum of (a) three times the employee's base salary; (b) the employee's
target incentive level for an award under the Company's stock option plan; (c)
the Company contributions made to the employee's account under the 401(k) Plan
during the year immediately before the change in control; and (d) the amount
provided for in the Company's executive perquisite program in effect on the
employee's date of termination. The employee would also receive continued
coverage under applicable welfare benefit plans for 12 months and the employee's
stock options would become fully vested and a cash payment would be made to the
employee for the Fair Market Value (as defined in the amendment). The employment
agreements provide for a comparison between (a) the tax effect of receiving the
sum of $1.00 less than three times the employee's base salary; and (b) the
benefit payable using the calculation in the employment agreement. This
comparison would be independently calculated by Arthur Andersen LLP and the
employee would be entitled to the greater amount on an after-tax basis.
 
                        ADDITIONAL INFORMATION ABOUT OUR
                        DIRECTORS AND EXECUTIVE OFFICERS
 
COMPLIANCE WITH SECTION 16(a) REPORTING
 
     The rules of the Securities and Exchange Commission ("SEC") require that
the Company disclose late filings of reports of stock ownership (and changes in
stock ownership) by its directors and executive officers. Based on Company
records and representations by its directors and executive officers, the Company
believes that during 1998 all filings were made in compliance with SEC
requirements.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Messrs. Buck, Gibbs and Neely are members of the Company's Compensation and
Benefits Committee. During 1998, neither Mr. Buck, Mr. Gibbs nor Mr. Neely were
officers or employees of the Company or any
 
                                       14
<PAGE>   18
 
of its subsidiaries, nor did any of them have any relationship with the Company
which requires disclosure under SEC requirements. From 1977 to December 1987,
Mr. Neely was Chief Executive Officer and Chairman of the Board of Directors of
the Company.
 
                  STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
 
     The following table shows certain information about stock ownership of all
persons known to the Company to own of record or beneficially more than 5% of
the outstanding Common Stock of the Company as of March 3, 1999. This
information is based upon information furnished to the Company by these persons
and statements filed with the SEC:
