It measures 0.5 inches wide, 0.75 inches high, and 4 inches in overall length. M42 cobalt HSS offers higher red hardness than standard M2 steel, making it well suited for machining tough alloys, stainless steels, and hardened materials where heat buildup is a concern. The ground finish ensures dimensional accuracy right out of the box, allowing machinists to grind a custom cutting edge profile with minimal stock removal. This blank is intended for use in manual and CNC lathes, shapers, and planers where the operator needs to form a purpose-ground single-point tool.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, toolrooms, and maintenance facilities that require custom-ground cutting tools. It is appropriate for both production and prototype environments where standard insert tooling does not meet the geometry required. Typical applications include turning, facing, threading, and boring operations performed on a lathe or shaper. The rectangle cross-section fits standard tool holders sized for 1\/2 inch by 3\/4 inch blanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction provides superior red hardness and wear resistance compared to standard M2\u003c\/li\u003e\n\u003cli\u003eGround finish delivers precise dimensional tolerances for accurate custom edge grinding\u003c\/li\u003e\n\u003cli\u003eRectangle profile fits standard tool holders accepting 1\/2 inch wide by 3\/4 inch high blanks\u003c\/li\u003e\n\u003cli\u003e4-inch overall length provides ample stock for multiple regrinds over the tool life\u003c\/li\u003e\n\u003cli\u003eSolid blank construction allows machinists to grind any single-point geometry required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or shop-stock tool bit blank for standard tool holders accepting a 1\/2 inch wide by 3\/4 inch high rectangle shank profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks are ground to a finished cutting geometry by a qualified machinist or toolroom grinder before use. Secure the blank in a tool holder or grinding fixture before grinding to avoid contact with the wheel while unsupported. Follow shop safety procedures including eye protection and wheel guards when grinding. Verify that the finished tool geometry matches the required clearance and rake angles for the workpiece material before mounting in the machine.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround or Unground\u003c\/strong\u003e: Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C44646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51704689262898,"sku":"C44646","price":257.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60ad7b6277d32761f6f8e42d0a61e36e_000d4b5b-e4d0-4c5b-b0a3-bffd47428929.jpg?v=1788424398","url":"https:\/\/voomisupply.com\/products\/cleveland-c44646-m42-cobalt-tool-bit-blank-1-2x3-4x4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
