It measures 1\/4 inch wide, 3\/8 inch high, and 2-1\/2 inches in overall length. M42 cobalt grade provides elevated red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for grinding custom single-point tools, form tools, and specialty profiles from scratch. Machinists and tool grinders use blanks like this when a standard off-the-shelf geometry does not meet the job requirement. The ground finish ensures consistent dimensions across the blank for accurate tool grinding setups.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in machine shop and toolroom environments where operators grind their own cutting tools to a custom profile. Typical applications include lathe tool grinding, boring bar fabrication, and specialty form tool production on manual or CNC lathes. The M42 cobalt composition handles difficult-to-machine materials such as hardened steels, stainless steel, and high-temperature alloys better than standard HSS. It is sold individually and is appropriate for production shops, toolrooms, and trade apprenticeship programs that require custom-ground tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel for improved red hardness and wear resistance over standard HSS grades\u003c\/li\u003e\n  \u003cli\u003eRectangle-ground blank provides a consistent, dimensionally accurate starting profile for tool grinding\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch wide by 3\/8 inch high cross-section fits standard small-bore tool holders and grinder fixtures\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch overall length allows material for regrinding or re-profiling multiple times\u003c\/li\u003e\n  \u003cli\u003eSold as a single piece with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool bit blank for manual and CNC lathe tool holders accepting 1\/4 inch by 3\/8 inch rectangular shank inserts, and compatible with standard bench and surface grinders used to profile HSS tool blanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding of tool bit blanks should be performed by a qualified machinist or toolroom technician using appropriate grinding wheels rated for cobalt high-speed steel. Eye protection and a wheel guard must be in place before grinding operations begin. Secure the blank firmly in a tool grinding fixture or vise to maintain consistent relief and rake angles during shaping. Allow the blank to cool adequately during grinding to prevent thermal damage to the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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: 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\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: C44602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693360677170,"sku":"C44602","price":111.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/538692d6d7028e9cba178448e0fea653.jpg?v=1788311224","url":"https:\/\/voomisupply.com\/products\/cleveland-c44602-m42-cobalt-tool-bit-blank-1-4x3-8x2-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
