Built from cobalt M42 high-speed steel, this cutter delivers strong heat and wear resistance during interrupted cuts in steel, stainless, and other hard materials. It features a 1.5-inch cut diameter, a 0.3125-inch cutting width, and a 1\/2-inch shank diameter for use in standard milling machine collets and arbors. The straight-tooth configuration provides clean, consistent cuts with predictable chip evacuation. With 16 teeth and a bright uncoated finish, it suits production and maintenance machining operations requiring accurate, repeatable keyseat dimensions.\u003c\/p\u003e\n\u003cp\u003eThis keyseat cutter is used in machine shops, maintenance facilities, and manufacturing environments where shaft-and-key assemblies require precisely sized Woodruff keyseats. It conforms to ANSI American Standard Number 1012, also referenced as Old Standard Number 25, making it a direct fit for applications specified to those standards. Typical install scenarios include drive shaft work, gearbox rebuilds, pulley assemblies, and precision component fabrication where keyseat geometry must match a standardized Woodruff key size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt M42 construction for improved heat resistance and extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e1.5-inch cut diameter and 0.3125-inch cutting width conform to ANSI Standard Number 1012 and Old Standard Number 25\u003c\/li\u003e\n  \u003cli\u003eStraight-tooth design provides consistent chip evacuation and smooth keyseat surfaces\u003c\/li\u003e\n  \u003cli\u003e16-tooth count balances feed rate flexibility with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch shank diameter fits standard milling machine collets and arbor holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation Woodruff keyseat cutter conforming to ANSI American Standard Number 1012 and Old Standard Number 25.

Ensure the machine spindle is fully stopped and the power is locked out before mounting or removing the cutter. Secure the shank firmly in the collet or arbor to the machine manufacturer specifications to prevent runout or pullout during cutting. Follow applicable shop safety standards and machine guarding requirements throughout operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Configuration\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Material Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmerican Standard Number\u003c\/strong\u003e: 1012\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOld Standard Number\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241631\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C21001012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697130733874,"sku":"C21001012","price":103.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54e9efc7a86ed0f1fb1aa085307f88db.jpg?v=1788349688","url":"https:\/\/voomisupply.com\/products\/value-collection-c21001012-woodruff-keyseat-cutter-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
