It uses a 3-blade plunger mechanism that contacts the chamfer surface and reads the included angle on a dial indicator. The gage covers a measurement range of 0 to 1\/2 inch in chamfer width and reads included angles from 90 to 127 degrees. All contact surfaces are ground for consistent accuracy. Machinists, toolmakers, and quality control technicians use this instrument in precision machining and inspection environments where chamfer consistency is critical.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for internal chamfer inspection on machined components in manufacturing, tool and die, and production quality settings. It is used wherever chamfered hole entries must be verified to a specified included angle, such as on bearing seats, valve bodies, hydraulic fittings, and similar precision-machined parts. The 3-blade plunger design centers itself in the chamfer, making it well suited for both one-off inspection and repetitive production checks. The unit ships in a deluxe padded case for storage and transport protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo setting master required — gage reads absolute included angle directly\u003c\/li\u003e\n  \u003cli\u003e3-blade plunger design provides self-centering contact with the chamfer surface\u003c\/li\u003e\n  \u003cli\u003eMeasures included angles from 90 to 127 degrees\u003c\/li\u003e\n  \u003cli\u003eChamfer width measurement range: 0 to 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003eAll ground surfaces for repeatable accuracy\u003c\/li\u003e\n  \u003cli\u003eIncludes deluxe padded case for protection and storage\u003c\/li\u003e\n  \u003cli\u003eElectronic indicator version available on request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for internal chamfer inspection on precision-machined holes with included angles between 90 and 127 degrees and chamfer widths up to 1\/2 inch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is used in inspection and quality control applications, not installed in a mechanical system.
