It measures 3\/8 inches wide, 1\/2 inches high, and 4 inches in overall length. M42 cobalt grade provides high hardness and heat resistance, making it well suited for grinding into single-point turning tools, boring bars, parting tools, and other custom cutting profiles. The blank arrives ground on all surfaces for consistent dimensional accuracy. Machinists and tool-and-die technicians use this blank as raw stock to form and sharpen cutting tools to a specific geometry for lathe, shaper, or planer work.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in machine shops, maintenance facilities, and production environments where operators grind their own cutting tools to match a specific workpiece material or operation. It is appropriate for cutting ferrous and non-ferrous metals, including harder alloys and stainless steels where M42 cobalt composition provides an advantage over standard M2 high-speed steel. The rectangle profile is the most common blank geometry for general-purpose single-point tool grinding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRectangle ground profile on all faces for dimensional consistency out of the package\u003c\/li\u003e\n  \u003cli\u003e10-degree bevel angle provides a starting geometry for tool grinding\u003c\/li\u003e\n  \u003cli\u003e4 inches overall length gives adequate stock for repeated resharpening over tool life\u003c\/li\u003e\n  \u003cli\u003e3\/8 inches wide by 1\/2 inches high cross-section fits standard tool holders for that blank size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose tool bit blank compatible with standard tool holders and grinding setups that accept a 3\/8 inches by 1\/2 inches rectangle blank cross-section.\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 before use. Use appropriate wheel dressing and grinding wheel selection for high-speed steel cobalt grades. Secure the blank firmly in a tool holder or grinding fixture before cutting; never attempt to use an unground blank as a cutting tool. Follow shop safety protocols including eye protection and proper ventilation when grinding.\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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1\/2 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\u003eBevel Angle\u003c\/strong\u003e: 10 degrees\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: C44623\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51696618799410,"sku":"C44623","price":128.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/655384fc48ae922357f4ff4432d03c97.jpg?v=1788344501","url":"https:\/\/voomisupply.com\/products\/cleveland-c44623-m42-cobalt-tool-bit-blank-3-8x1-2x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
