The cutter measures 21\/32 inches in diameter with a 17\/64-inch cutting width, making it sized for standard 5\/16-inch bolt T-slots. The 1\/2-inch shank diameter fits common milling machine collets and arbors. With 8 straight teeth and a bright uncoated finish, this cutter is suited for general-purpose T-slot milling where high-speed steel performance is required but cobalt-grade heat resistance is preferred. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis T-slot cutter is used in manual mills, knee mills, and CNC machining centers for cutting T-slots in machine tables, fixtures, and workholding components. The 39\/64-inch neck length provides clearance for the slot walls during the cut, and the 2-11\/16-inch overall length accommodates standard tool holders. The M42 cobalt steel construction handles the elevated cutting temperatures common in interrupted cuts and harder steels. This style of cutter is a standard tool in job shops, maintenance facilities, and production machine shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e21\/32-inch cutter diameter sized for 5\/16-inch bolt T-slots\u003c\/li\u003e\n  \u003cli\u003e17\/64-inch cutting width for accurate slot dimension\u003c\/li\u003e\n  \u003cli\u003e8 straight teeth for clean, consistent chip load per pass\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003e39\/64-inch neck length provides clearance in deep or narrow slot entries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard T-slot cutter for use in milling machines and machining centers accepting a 1\/2-inch shank, suitable for cutting 5\/16-inch bolt T-slots in workholding fixtures, machine tables, and similar components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Secure the 1\/2-inch shank in a collet or arbor rated for the shank diameter and confirm runout before cutting. Power down and lock out the machine spindle before loading or removing the cutter.
