At 3\/16 inches wide by 3\/16 inches high with an overall length of 2-1\/2 inches, this blank provides the raw stock needed to produce form tools, lathe bits, boring tools, and specialty profiles. M42 cobalt steel offers higher red hardness and wear resistance compared to standard M2 high-speed steel, making it a practical choice for cutting harder workpiece materials or for applications where tool life is a primary concern.\u003c\/p\u003e\n\u003cp\u003eThis blank is suited for use in machine shops, toolrooms, and maintenance environments where operators grind tools to specific geometries. It is appropriate for manual lathes, turret lathes, and similar single-point or formed-tool applications where a custom ground profile is required. The square cross-section allows for consistent tool holding in standard bit holders and blocks during the grinding process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved red hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section: 3\/16 inches wide by 3\/16 inches high\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inches overall length provides adequate stock for regrinding\u003c\/li\u003e\n  \u003cli\u003eGround finish for consistent dimensional accuracy out of the package\u003c\/li\u003e\n  \u003cli\u003eSquare end shape suits standard tool holders and grinding setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a raw grinding blank for use in standard tool bit holders accepting 3\/16 inch square shank stock.

Eye protection and grinding guards must be in place during all grinding operations per applicable shop safety standards. Ensure the tool holder or bit block is clean and free of debris before seating the finished tool. Inspect the ground edge for cracks or chips before placing the tool in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3\/16 inches\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: 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: C44540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691952767282,"sku":"C44540","price":41.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59df34bd721b21c34b4c197416650d37.jpg?v=1788291367","url":"https:\/\/voomisupply.com\/products\/cleveland-c44540-tool-bit-blank-3-16in-m42-cobalt-square","provider":"Voomi Supply","version":"1.0","type":"link"}
