STARRETT-WEBBER GAGE BLOCKS - JW Donchin CO.

STARRETT-WEBBERGAGE BLOCKSAngle Gage Block SetsWebber Angle Gage Blocks permit fast,simple and accurate measurements ofany angle. They are far superior to sinebar measuring methods, that involvetrigonometric formulae and complexstacks of gage blocks.Angle gage blocks come in threeaccuracies, croblox ® Reference AngleBlocks with a 1-second accuracy, steelCalibration Grade Angle Blocks with2-second accuracy, and steel WorkingGrade Angle Blocks with 5-secondaccuracy. Each grade can be purchased insets that will measure in steps of onesecond,one-minute or one-degree to suitany need. (See angle block specificationinformation on next two pages.)◆ Reference Angle Blockscroblox ® : 1-second accuracyDesigned for optical or as referencestandards for autocollimators,spectrometers, etc. They areunsurpassed for use in aerospace,optical and precision instrument fields.◆ Calibration Angle BlocksSteel: 2-second accuracyThe same high quality as the ReferenceGrade Angle Blocks◆ Working Angle BlocksSteel: 5-second accuracyThese angles are designed for shop ortool room. The longer gaging surfacesare made for use with an indicator.These blocks reduce set-up timeand minimize error in grinding bothsimple and compound anglesNote: The catalog numbers andspecifications of our angle gage blockshave been changed in response to updatedrequirements concerning the application ofthe uncertainty of measurement. See thenext two pages for information regardingthe specifications of our angle blocks.All sets furnished in case. Cases also availableseparately.
