It uses a 3-blade plunger mechanism that contacts the chamfer surface directly, reading included angles from 0 to 90 degrees across a measurement range of 1 to 2 inches. The body and blades are constructed from hardened tool steel with all ground surfaces for dimensional accuracy and long service life. No setting master is required to use this gage, which reduces setup time on the shop floor. Machinists, quality control technicians, and tool-and-die trades use this instrument as part of in-process and final inspection routines.\u003c\/p\u003e\n\u003cp\u003eThe 63687 is suited for inspecting internal chamfers on bored holes, counterbores, and countersinks in production machining environments, tool rooms, and job shops. It is appropriate for both ferrous and non-ferrous workpieces where chamfer angle consistency is a quality requirement. The gage ships in a deluxe padded case that protects the instrument during storage and transport. Electronic indicator configurations are available on request for applications requiring digital readout or data output to a statistical process control system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-blade plunger design provides stable, repeatable contact on internal chamfer surfaces\u003c\/li\u003e\n  \u003cli\u003eMeasures included angles from 0 to 90 degrees with no setting master required\u003c\/li\u003e\n  \u003cli\u003eHardened tool steel construction with all ground surfaces for accuracy and durability\u003c\/li\u003e\n  \u003cli\u003eMeasurement range of 1 to 2 inches covers common bore chamfer sizes\u003c\/li\u003e\n  \u003cli\u003eIncludes a deluxe padded carrying and storage case\u003c\/li\u003e\n  \u003cli\u003eElectronic indicator option available on request for digital or SPC output\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use internal chamfer gage for machined bores and countersunk features within the 1 to 2 inch measurement range and 0 to 90 degree included angle range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is installed and operated by machinists and quality control technicians — no permanent mounting or wiring is required. Before use, inspect the blades and plunger for wear or contamination that could affect readings. Store the gage in its padded case when not in use to prevent damage to the ground surfaces. Electronic indicator configurations should be connected and configured according to the indicator manufacturer guidelines before taking measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Internal Chamfer Gage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: 3-Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Included Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Included Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Face Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: All Ground Surface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63687\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542151921970,"sku":"63687","price":848.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bd78b2fb0d231878b14206345e2da0b.jpg?v=1785893783","url":"https:\/\/voomisupply.com\/products\/starrett-63687-internal-chamfer-gage-1-2-in-3-blade","provider":"Voomi Supply","version":"1.0","type":"link"}
