It measures 3\/8 inches wide, 3\/4 inches high, and 6 inches in overall length. The blank arrives ground, providing a consistent surface finish that allows machinists to grind custom profiles, form tools, single-point turning tools, or specialty cutting geometries directly from stock. M42 cobalt grade offers elevated heat resistance and hardness retention compared to standard M2 high-speed steel, making it a reliable choice for cutting harder workpiece materials at higher speeds without premature edge breakdown.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is suited for use in manual lathes, boring mills, and tool-and-cutter grinder setups in both job shop and production machining environments. Machinists and toolmakers use blanks like this when a standard insert or catalog cutting tool does not match the required profile. The 6-inch length provides enough stock to grind multiple tool geometries or to regrind the same tool over an extended service life. Applicable in ferrous and non-ferrous machining applications where cobalt-grade tooling is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved red hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eGround finish on all faces for dimensional consistency and ease of custom grinding\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section: 3\/8 inches wide by 3\/4 inches high\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides ample stock for custom tool grinding or multiple regrinds\u003c\/li\u003e\n\u003cli\u003eSold individually, allowing single-unit procurement for low-volume or prototype work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tool bit blank for use in standard tool bit holders and grinder setups that accept rectangular high-speed steel blanks of this cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks require grinding to final geometry before use in a cutting application. Use a bench or surface grinder with an appropriate wheel rated for high-speed steel. Follow all shop safety protocols, including eye protection and proper wheel guarding, when grinding. Ensure the tool holder or post is sized to match the 3\/8-inch by 3\/4-inch cross-section before mounting.\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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 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: C44642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715357573426,"sku":"C44642","price":275.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e36ef8c2f3adcc9d891b2f23ad76120.jpg?v=1788512645","url":"https:\/\/voomisupply.com\/products\/cleveland-c44642-m42-cobalt-tool-bit-blank-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
