It measures 0.5 inches wide, 1 inch high, and 8 inches overall length, providing stock material for grinding custom single-point cutting tools, form tools, or lathe bits to exact profiles. M42 cobalt grade offers higher red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. Machinists and tool-and-die professionals typically grind these blanks to finished geometry on a bench or surface grinder.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in machine shops, maintenance facilities, and production environments where custom ground tooling is required. It is appropriate for turning, boring, threading, and form-relief applications on manual lathes and screw machines. The ground finish on all faces ensures dimensional accuracy and provides a consistent starting surface for precision tool grinding. Shops that run difficult-to-machine alloys, stainless steels, or heat-resistant superalloys commonly stock M42 cobalt blanks for their improved hot hardness over standard high-speed steel grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel for increased red hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRectangle ground profile on all faces for accurate starting geometry\u003c\/li\u003e\n  \u003cli\u003e0.5 inches wide by 1 inch high cross-section suits a range of tool holder sizes\u003c\/li\u003e\n  \u003cli\u003e8-inch overall length provides material for multiple regrind cycles or multiple tools\u003c\/li\u003e\n  \u003cli\u003eGround finish reduces stock removal time when sharpening to final geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose ground tool bit blank for use in standard tool holders and grinding fixtures that accept 1\/2 inch by 1 inch rectangular shank stock on manual and CNC lathes, screw machines, and boring applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to final geometry by a qualified machinist or tool grinder using appropriate bench, pedestal, or surface grinding equipment. Ensure the grinder wheel is rated for high-speed steel and cobalt alloys before proceeding. Wear appropriate eye and face protection during all grinding operations. Secure the blank firmly in a tool grinding fixture or vise to maintain accurate relief and rake angles during sharpening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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\u003eWidth\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches (203.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C44651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51702095380786,"sku":"C44651","price":467.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3487340b747c4c1ee9ff24d901bb78c3.jpg?v=1788409077","url":"https:\/\/voomisupply.com\/products\/cleveland-c44651-m42-cobalt-tool-bit-blank-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
