It measures 0.25 inches wide, 0.25 inches high, and 2.5 inches in overall length. M42 cobalt grade provides increased hardness and heat resistance compared to standard M2 high-speed steel, making it well suited for cutting harder workpiece materials at elevated speeds. The blank arrives ground on all surfaces, giving machinists a consistent, accurate starting point for custom tool geometry. This bit blank is intended for use by machinists and toolroom professionals who grind their own single-point lathe tools, form tools, and specialty cutting tools to exact profiles.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in production and toolroom environments where standard insert tooling does not meet the required geometry. Typical applications include single-point turning, boring, and threading operations on manual and CNC lathes. The M42 cobalt composition handles stainless steels, nickel alloys, and other difficult-to-machine materials that would quickly degrade a conventional high-speed steel blank. Machinists grind the blank to the required rake, relief, and nose radius angles on a bench or surface grinder before installation in a tool holder or boring bar.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved hot hardness and wear resistance over standard HSS grades\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 0.25 inches wide by 0.25 inches high for consistent seating in standard tool holders\u003c\/li\u003e\n  \u003cli\u003e2.5 inches overall length provides adequate stock for multiple regrinds over the tool life\u003c\/li\u003e\n  \u003cli\u003eAll surfaces ground to close tolerances for accurate tool geometry when custom profiling\u003c\/li\u003e\n  \u003cli\u003eSquare end shape allows the machinist to grind any desired cutting geometry from a clean, uniform blank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 0.25-inch square tool bit blank for use in toolroom and production lathe applications requiring M42 cobalt high-speed steel ground blanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to final geometry by a qualified machinist using a bench grinder or surface grinder with an appropriate grinding wheel rated for high-speed steel. Secure the blank firmly in a tool holder or grinding fixture before grinding to prevent movement. Inspect the finished cutting edge for proper relief and rake angles before mounting in the lathe tool post. Always wear appropriate eye protection during grinding operations and ensure the grinder guard is in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\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: Square\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\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: C44575\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692007719218,"sku":"C44575","price":54.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85b398ca5db7b98ddec1d903b7865f31.jpg?v=1788291954","url":"https:\/\/voomisupply.com\/products\/cleveland-c44575-m42-cobalt-tool-bit-blank-0-25x2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
