It uses a 3-blade plunger mechanism to contact the chamfer surface and returns a direct reading on the dial indicator. The measurement range spans 0 to 1 inch, and the tool accommodates included angles from 90 to 127 degrees. All ground surfaces and hardened tool steel construction keep the gage in calibration through repeated shop use. Machinists, toolmakers, and quality control technicians use this gage for incoming inspection, in-process verification, and final part acceptance.\u003c\/p\u003e\n\u003cp\u003eThe 63690 is suited for inspecting internal chamfers and countersinks on machined components in job shop, production, and maintenance environments. The direct-reading dial eliminates the need for a separate setting master, which reduces setup time on the floor. It ships in a deluxe padded case, keeping the gage protected between uses. Electronic indicator versions are available on request for applications that require data output or digital readout integration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-blade plunger design contacts the chamfer at three points for consistent, repeatable readings\u003c\/li\u003e\n  \u003cli\u003eNo setting master required — gage reads directly, reducing setup steps\u003c\/li\u003e\n  \u003cli\u003eHardened tool steel construction with all ground surfaces for long-term accuracy\u003c\/li\u003e\n  \u003cli\u003eMeasures included angles from 90 to 127 degrees across a 0 to 1 inch range\u003c\/li\u003e\n  \u003cli\u003eWhite dial face for clear readability in shop lighting conditions\u003c\/li\u003e\n  \u003cli\u003eIncludes a deluxe padded case for storage and transport protection\u003c\/li\u003e\n  \u003cli\u003eElectronic indicator option available on request for digital readout or data collection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for measuring internal chamfers and countersinks on machined parts where the included angle falls between 90 and 127 degrees and the chamfer diameter does not exceed 1 inch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is a hand-held measurement instrument and does not require mounting or wiring. Handle with clean, dry hands or cotton inspection gloves to prevent corrosion on ground surfaces. Store in the supplied padded case when not in use to protect the plunger blades and dial mechanism. Inspect the plunger blades for wear or damage before each use session to ensure measurement integrity.\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\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: 0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Included Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Included Angle\u003c\/strong\u003e: 127 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\u003eWeight\u003c\/strong\u003e: 2.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 63690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539274072370,"sku":"63690","price":648.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493202da41b12bda89533302742d871e.jpg?v=1785837544","url":"https:\/\/voomisupply.com\/products\/starrett-63690-internal-chamfer-gage-0-to-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
