It measures 3\/4 inch wide, 1 inch high, and 6 inches in overall length. M42 cobalt HSS offers higher red hardness and wear resistance compared to standard M2 grades, making this blank suitable for machining tough, abrasive, or heat-resistant alloys. The blank arrives ground and ready for the toolmaker or machinist to profile and sharpen to the required cutting geometry. It is used in production toolrooms, job shops, and maintenance departments where custom single-point lathe tools, form tools, or specialty cutters are ground in-house.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is suited for applications involving hard-to-machine materials such as stainless steels, titanium alloys, and nickel-based superalloys where standard HSS grades lose hardness at elevated cutting temperatures. The 6-inch length provides sufficient stock for grinding multiple profiles or for use in boring bars and toolholders that accept 3\/4-inch blanks. It is a standard choice for manual and CNC lathe tool grinding operations in both light manufacturing and heavy-duty production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction provides superior red hardness for cutting difficult alloys\u003c\/li\u003e\n  \u003cli\u003eRectangle ground profile allows precise in-house tool geometry grinding\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch width by 1 inch height cross-section fits standard toolholders and grinding fixtures\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length offers generous stock for multiple regrinds\u003c\/li\u003e\n  \u003cli\u003eGround finish ensures dimensional accuracy and consistent seating in toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or shop-ground tool blank for lathes and boring applications requiring a 3\/4 inch by 1 inch rectangular HSS bit blank up to 6 inches in overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground by a qualified toolmaker or machinist using a bench or surface grinder fitted with an appropriate grinding wheel for high-speed steel. Secure the blank in a proper tool grinding fixture to maintain accurate rake and relief angles. Always wear eye protection and follow shop safety procedures when grinding. Verify the finished tool geometry and edge condition before mounting in the toolholder and bringing the machine to operating speed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\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\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: C44660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693528678706,"sku":"C44660","price":512.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1da2e485069b393171147f73a32a86f.jpg?v=1788313694","url":"https:\/\/voomisupply.com\/products\/cleveland-c44660-m42-cobalt-tool-bit-blank-6-inch-rectangle","provider":"Voomi Supply","version":"1.0","type":"link"}
