Organization, Consolidation and Presentation of Financial Statements [Abstract]
BACKGROUND AND BASIS OF PRESENTATION	BACKGROUND AND BASIS OF PRESENTATION W.W. Grainger, Inc. is a broad line, business-to-business distributor of maintenance, repair and operating (MRO) products and services with operations primarily in North America (N.A.), Japan and the United Kingdom (U.K.). In this report, the words “Company” or “Grainger” mean W.W. Grainger, Inc. and its subsidiaries, except where the context makes it clear that the reference is only to W.W. Grainger, Inc. itself and not its subsidiaries. The Company's Condensed Consolidated Financial Statements (Financial Statements) and the related notes are unaudited and should be read in conjunction with the consolidated financial statements and associated notes for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 24, 2021 (2020 Form 10-K). The Condensed Consolidated Balance Sheet as of December 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the disclosures required by accounting principles generally accepted in the United States of America (U.S.) for complete financial statements. The unaudited financial information reflects all adjustments (primarily consisting of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the statements contained in this report. Changes to Reportable Segments Effective January 1, 2021, Grainger's two reportable segments are High-Touch Solutions N.A. and Endless Assortment. On March 8, 2021, the Company provided investors with segment summary historical financial information and segment historical data that is consistent with its new reportable segment structure and reflective of the intersegment accounting policies described in Note 10 - Segment Information. The Company's High-Touch Solutions N.A. segment provides value-added MRO solutions that are rooted in deep product knowledge and customer expertise. This segment includes the Grainger-branded businesses in the U.S., Canada, Mexico and Puerto Rico. The Company’s Endless Assortment segment provides a simple, transparent and streamlined experience for customers to shop millions of products online. This segment includes the Company’s Zoro Tools, Inc. (Zoro) businesses in the U.S. and U.K. and MonotaRO Co., Ltd. (MonotaRO), which operates predominately in Japan. The remaining international High-Touch Solutions businesses, operating primarily in the U.K., are classified as “Other” to reconcile to consolidated results. These businesses individually do not meet the criteria of a reportable segment.

Accounting Policies [Abstract]
NEW ACCOUNTING STANDARDS	NEW ACCOUNTING STANDARDS Accounting Pronouncements Recently Adopted In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU clarifies and simplifies accounting for income taxes by eliminating certain exceptions for intra-period tax allocation principles, the methodology for calculating income tax rates in an interim period, and recognition of deferred taxes for outside basis differences in an investment, among other updates. The effective date of this ASU was for fiscal years and interim periods beginning after December 15, 2020. The Company adopted this ASU effective January 1, 2021 and it did not have a material impact on the Financial Statements. In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), Clarifying the Interactions between Topic 321, Topic 323 and Topic 815 . This ASU simplifies the understanding and application of the codification topics by eliminating inconsistencies and providing clarifications. The effective date of this ASU was for fiscal years and interim periods beginning after December 15, 2020. The Company adopted this ASU effective January 1, 2021 and it did not have a material impact on the Financial Statements. In October 2020, the FASB issued ASU 2020-10, Codification Improvements. These amendments improve consistency by amending the codification to include all disclosure guidance in the appropriate disclosure sections and clarifies application of various provisions in the codification by amending and adding new headings, cross referencing to other guidance and refining or correcting terminology. The effective date of this ASU was for fiscal years and interim periods beginning after December 15, 2020. The Company adopted this ASU effective January 1, 2021 and it did not have a material impact on the Financial Statements. Accounting Pronouncements Recently Issued In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting as modified by subsequently issued ASU 2021-01. This update provides optional expedients and exceptions for applying generally accepted accounting principles to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. The guidance is effective upon issuance and generally can be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is evaluating the impact of this ASU and does not expect a material impact on the Financial Statements.

REVENUE

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Company revenue is primarily comprised of MRO product sales and related activities, such as freight and services. Total service revenue is not material and accounted for approximately 1% of the Company's revenue for the three and nine months ended September 30, 2021 and 2020, respectively. Grainger serves a large number of customers in diverse industries, which are subject to different economic and market-specific factors. The Company's presentation of revenue by segment and industry most reasonably depicts how the nature, amount, timing and uncertainty of Company revenue and cash flows are affected by economic and market-specific factors. In addition, the segments have unique underlying risks associated with customer purchasing behaviors. In the High-Touch Solutions N.A. segment, more than two-thirds of revenue is derived from customer contracts whereas in the Endless Assortment segment, a majority of revenue is derived from customer spot buys. The following table presents the Company's percentage of revenue by reportable segment and by major customer industry: Three Months Ended September 30, 2021 2020 High-Touch Solutions N.A.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETSGrainger tests reporting units' goodwill and intangible assets for impairment annually during the fourth quarter and more frequently if impairment indicators exist. Accordingly, Grainger performs quarterly qualitative assessments of significant events and circumstances such as reporting units' historical and current results, assumptions regarding future performance, strategic initiatives and overall economic factors, including the current global outbreak of the Coronavirus (COVID-19 pandemic) and macro-economic developments, to determine the existence of potential indicators of impairment and assess if it is more likely than not that the fair value of reporting units' goodwill or intangible assets is less than their carrying value. If indicators of impairment are identified, a quantitative impairment test is performed. The Company did not identify any significant events or changes in circumstances that indicated the existence of impairment indicators during the three and nine months ended September 30, 2021. As such, quantitative assessments were not required.

Debt was issued as follows: • In May 2017, $400 million payable in 30 years and carries a 4.20% interest rate, payable semi-annually. • In May 2016, $400 million payable in 30 years and carries a 3.75% interest rate, payable semi-annually. • In June 2015, $1 billion payable in 30 years and carries a 4.60% interest rate, payable semi-annually. The Company may redeem the Senior Notes in whole at any time or in part from time to time at a “make-whole” redemption price prior to their respective maturity dates. The redemption price is calculated by reference to the then-current yield on a U.S. treasury security with a maturity comparable to the remaining term of the Senior Notes plus 20-25 basis points, together with accrued and unpaid interest, if any, at the redemption date. Additionally, if the Company experiences specific kinds of changes in control, it will be required to make an offer to purchase the Senior Notes at 101% of their principal amount plus accrued and unpaid interest, if any, at the date of purchase. Within one year of the maturity date, the Company may redeem the Senior Notes in whole at any time or in part at 100% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. At the time of issuance, costs and discounts of approximately $24 million, representing underwriting fees and other expenses, were recorded as a contra-liability within Long-term debt and are being amortized to interest expense over the term of the Senior Notes. (2) In February 2020, the Company issued $500 million of unsecured 1.85% Senior Notes (1.85% Notes) and used the proceeds to repay the British pound term loan, Euro term loan and the Canadian dollar revolving credit facility, and to fund general working capital needs. The 1.85% Notes mature in February 2025 and they require no principal payments until the maturity date and interest is payable semi-annually on February 15 and August 15, beginning in August 2020. Prior to January 2025, the Company may redeem the 1.85% Notes in whole at any time or in part from time to time at a “make-whole” redemption price. This redemption price is calculated by reference to the then-current yield on a U.S. treasury security with a maturity comparable to the remaining term of the 1.85% Notes plus 10 basis points, together with accrued and unpaid interest, if any, at the redemption date. Additionally, if the Company experiences specific kinds of changes in control, it will be required to make an offer to purchase the 1.85% Notes at 101% of their principal amount plus accrued and unpaid interest, if any, at the date of purchase. On or after January 15, 2025, the Company may redeem the 1.85% Notes in whole at any time or in part from time to time at 100% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. At the time of issuance, costs and discounts of approximately $5 million, representing underwriting fees and other expenses, were recorded as a contra-liability within Long-term debt and are being amortized to interest expense, net over the term of the 1.85% Notes. In connection with the 1.85% Notes, in February 2020, the Company entered into derivative instrument agreements to manage its risks associated with interest rates on the 1.85% Notes and foreign currency fluctuations related to the financing of international operations. See Note 7 to the Financial Statements for further discussion of these derivative instruments and the Company's hedge accounting policies. (3) In August 2020, MonotaRO Co. Ltd., entered into a ¥9 billion term loan agreement to fund technology investments and the expansion of its distribution center network. The Japanese Yen term loan matures in 2024, payable over four equal semi-annual principal installments in 2023 and 2024, and bears average interest at 0.05%. (4) The estimated fair value of the Company’s Senior Notes was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as Level 2 within the fair value hierarchy. The carrying value of other long-term debt approximates fair value due to their variable interest rates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company maintains various agreements with bank counterparties that permit the Company to enter into "over-the-counter" derivative instrument agreements to manage its risk associated with interest rates and foreign currency fluctuations. In February 2020, the Company entered into certain derivative instrument agreements to manage its risk associated with interest rates on its 1.85% Notes and foreign currency fluctuations in connection with its foreign currency-denominated intercompany financing arrangements. The Company did not enter into these agreements for trading or speculative purposes. Fair value hedges The Company uses fair value hedges primarily to hedge a portion of its fixed-rate long-term debt via interest rate swaps. Changes in the fair value of the interest rate swap, along with the gain or loss on the hedged item, is recorded in earnings under the same line item, interest expense, net. The notional amount of the Company’s outstanding fair value hedges as of September 30, 2021 and December 31, 2020 was $500 million. Cash flow hedges The Company uses cash flow hedges primarily to hedge the exposure to variability in forecasted cash flows from foreign currency-denominated intercompany borrowings via cross-currency swaps. Gains or losses on the cross-currency swaps are reported as a component of Accumulated other comprehensive earnings (losses) (AOCE) and reclassified into earnings in the same period during which the hedged transaction affects earnings. The notional amount of the Company’s outstanding cash flow hedges as of September 30, 2021 and December 31, 2020 was approximately $34 million. The effect of the Company's fair value and cash flow hedges on the Company's Condensed Consolidated Statement of Earnings for the three and nine months ended September 30, 2021 and 2020 is as follows (in millions of dollars): Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Interest expense, net Other, net Interest expense, net Other, net Interest expense, net Other, Net Interest expense, net Other, Net Gain or (loss) recognized in earnings Fair value hedge: Hedged item $ 3 $ — $ — $ — $ 12 $ — $ (22) $ — Interest rate swap designated as hedging instrument $ (3) $ — $ — $ — $ (12) $ — $ 22 $ — Cash flow hedge: Hedged item $ — $ (1) $ — $ — $ — $ — $ — $ — Cross-currency swap designated as hedging instrument $ — $ 1 $ — $ — $ — $ — $ — $ — The effect of the Company’s fair value and cash flow hedges on AOCE for the three and nine months ended September 30, 2021 and 2020 was not material.

Intersegment sales transactions, which are sales between Grainger businesses in separate reportable segments, are eliminated within the segment to present only the impact of third-party sales.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES AND LEGAL MATTERS	CONTINGENCIES, LEGAL MATTERS, COMMITMENTS AND OTHER CONTRACTUAL OBLIGATIONS Contingencies and Legal Matters From time to time the Company is involved in various legal and administrative proceedings, including claims related to product liability, safety or compliance; privacy and cybersecurity matters; negligence; contract disputes; environmental issues; unclaimed property; wage and hour laws; intellectual property; advertising and marketing; consumer protection; pricing (including disaster or emergency declaration pricing statutes); employment practices; regulatory compliance, including as to trade and export matters; anti-bribery and corruption; and other matters and actions brought by employees, consumers, competitors, suppliers, customers, governmental entities and other third parties. As previously disclosed, beginning in the fourth quarter of 2019, Grainger, KMCO, LLC (KMCO) and other defendants have been named in several product liability-related lawsuits in the Harris County, Texas District Court relating to an explosion at a KMCO chemical refinery located in Crosby, Harris County, Texas on April 2, 2019. The complaints in which Grainger has been named, which to date encompass 16 lawsuits and approximately 186 plaintiffs, seek recovery of compensatory and other damages and relief in relation to personal injury, including one death and various other alleged injuries. On May 8, 2020, KMCO filed a voluntary petition in the United States Bankruptcy Court for the Southern District of Texas for relief under Chapter 7 of Title 11 of the United States Bankruptcy Court in the case KMCO, LLC, No. 20-60028. As a result of the Chapter 7 proceedings, the claims against KMCO in the Harris County lawsuits were stayed. Effective January 1, 2021, the Bankruptcy Court lifted the stay with respect to KMCO. On December 16, 2020, KMCO, the trustee of its estate and ORG Chemical Holdings, LLC, KMCO’s parent company (“ORG”), filed a property damage lawsuit relating to the KMCO chemical refinery incident against Grainger and another defendant in the Harris County, Texas District Court, which seeks unspecified damages (the “KMCO Case”). On April 1, 2021, 24 individual plaintiffs filed a petition in intervention seeking to be added as plaintiffs in the KMCO Case and seeking unspecified damages. On March 24, 2021, Indian Harbor Insurance Company, together with other insurance companies and underwriters, filed a property damage lawsuit relating to the KMCO chemical refinery incident against Grainger and another defendant in the Harris County, Texas District Court, seeking reimbursement of insurance payments made to or on behalf of KMCO and ORG, the insured parties under their respective policies, and other damages. Grainger is investigating each of the various claims against the Company relating to the KMCO chemical refinery incident, which are at an early stage, and intends to contest these matters vigorously. Also, as a government contractor selling to federal, state and local governmental entities, the Company may be subject to governmental or regulatory inquiries or audits or other proceedings, including those related to contract administration, pricing and product compliance. From time to time, the Company has also been named, along with numerous other nonaffiliated companies, as a defendant in litigation in various states involving asbestos and/or silica. These lawsuits typically assert claims of personal injury arising from alleged exposure to asbestos and/or silica as a consequence of products manufactured by third parties purportedly distributed by the Company. While several lawsuits have been dismissed in the past based on the lack of product identification, if a specific product distributed by the Company is identified in any pending or future lawsuits, the Company will seek to exercise indemnification remedies against the product manufacturer to the extent available. In addition, the Company believes that a substantial number of these claims are covered by insurance. The Company has entered into agreements with its major insurance carriers relating to the scope, coverage and the costs of defense, of lawsuits involving claims of exposure to asbestos. The Company believes it has strong legal and factual defenses and intends to continue defending itself vigorously in these lawsuits. While the Company is unable to predict the outcome of any of these proceedings and other matters, it believes that their ultimate resolution will not have, either individually or in the aggregate, a material adverse effect on the Company’s consolidated financial condition or results of operations.

This redemption price is calculated by reference to the then-current yield on a U.S. treasury security with a maturity comparable to the remaining term of the 1.85% Notes plus 10 basis points, together with accrued and unpaid interest, if any, at the redemption date. Additionally, if the Company experiences specific kinds of changes in control, it will be required to make an offer to purchase the 1.85% Notes at 101% of their principal amount plus accrued and unpaid interest, if any, at the date of purchase. On or after January 15, 2025, the Company may redeem the 1.85% Notes in whole at any time or in part from time to time at 100% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. At the time of issuance, costs and discounts of approximately $5 million, representing underwriting fees and other expenses, were recorded as a contra-liability within Long-term debt and are being amortized to interest expense, net over the term of the 1.85% Notes. In connection with the 1.85% Notes, in February 2020, the Company entered into derivative instrument agreements to manage its risks associated with interest rates on the 1.85% Notes and foreign currency fluctuations related to the financing of international operations. See Note 7 to the Financial Statements for further discussion of these derivative instruments and the Company's hedge accounting policies. (3) In August 2020, MonotaRO Co. Ltd., entered into a ¥9 billion term loan agreement to fund technology investments and the expansion of its distribution center network. The Japanese Yen term loan matures in 2024, payable over four equal semi-annual principal installments in 2023 and 2024, and bears average interest at 0.05%. (4) The estimated fair value of the Company’s Senior Notes was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as Level 2 within the fair value hierarchy. The carrying value of other long-term debt approximates fair value due to their variable interest rates.
