1 scOPE
This Standard applies to portable power tools fordrilling grinding, polishing, sawing, and driving threaded fasteners and hand tools for driving threadedfasteners.Other tools not classed as percussion tools be-long in this category and may be added by revision oraddition through the usual procedure.
This Standard includes dimensions and tolerances forboth driving and driven elements where such coordi-nation is important and not established by reference tothe pertinent American National Standards.All dimen-sions are in inches and millimeters.1
2DEFINITIONS
percussion tools: hammers, chisels, scalers, tampers, claydiggers, and rock drills. Percussion tools are excludedfrom this Standard.
rourding oalues: when the next digit beyond the last digitto be retained is
(a) less than 5,the last digit to be retained is notchanged
(b 5 or more, the last digit to be retained is increasedby one.
tool: as used in this Standard, a portable device for per-forming a mechanical operation with power from com-pressed air or electricity and hand operated.

5 GAGE USE AND DESIGN
The illustrations shown herein are descriptive, not re-strictive, and not intended to preclude the manufacturerof products or gages which are otherwise in accordancewith this Standard.
Manufacturers may use gages with tighter dimen-sions or tolerances than shown herein to ensure prod-uct acceptance.
Tolerances on gage dimensions within the Standardrepresent new manufactured or purchased gage sizes.The extreme size for all limit (GO and NO Go) gagesshall not exceed the extreme limits of products specifiedwithin the Standard. All variations (manufacturing tol-erance,calibration error，wear allowance,etc.) in thegages, whatever their cause or purpose, shall bring thesegages within the extreme limits of this gage size speci-fied within this Standard. Thus, a gage that represents niionumlimitmtel oarae pbruas AE wise, the gage that represents a maximum limit may be smaller , but never larger , than the maximum size spec-ified for the product standard.
