It measures 5\/16 inches wide by 5\/16 inches high with an overall length of 2.5 inches. Tool bit blanks are unfinished cutting tool stock that machinists grind to a custom profile for use in lathe, shaper, or planer operations. M42 cobalt steel offers higher hot hardness and wear resistance compared to standard M2 high-speed steel, making this blank well suited for machining hard or abrasive workpiece materials. The square cross-section and ground finish provide a consistent starting geometry for precision tool grinding.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is intended for use in machine shops, tool rooms, and maintenance environments where custom-ground single-point cutting tools are required. It fits standard tool holders and lantern-style tool posts designed for 5\/16-inch square shanks. Typical applications include turning, facing, boring, and threading operations on metal lathes. The M42 grade is particularly effective when cutting stainless steel, titanium, and other high-strength alloys that generate significant heat at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for superior hot hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eSquare ground cross-section — 5\/16 inches wide by 5\/16 inches high — provides consistent tool geometry\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length offers sufficient stock for grinding and regrinding multiple times\u003c\/li\u003e\n  \u003cli\u003eGround finish ensures dimensional accuracy before custom tool profile is applied\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 5\/16-inch square tool holders and lantern tool posts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-inch square tool bit blank for use in tool holders and tool posts that accept 5\/16-inch square shank cutting tools on metal lathes and similar machine tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to a final cutting profile by a machinist or tool grinder before use. Use a bench or tool grinder with an appropriate wheel for high-speed steel; M42 cobalt responds best to aluminum oxide grinding wheels. Ensure the workpiece machine is fully powered down and locked out before changing or setting a tool bit in the tool holder. Follow shop safety practices including eye protection during all grinding operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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\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: C44545\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716284285234,"sku":"C44545","price":50.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2418158e40f224880129c73c7cfb585a.jpg?v=1788523939","url":"https:\/\/voomisupply.com\/products\/cleveland-c44545-tool-bit-blank-5-16-in-square-m42-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
