Cobalt HSS blanks are used by machinists and tool grinders to create custom single-point lathe tools, form tools, and specialty cutting profiles. The M42 grade offers higher red hardness than standard M2 HSS, making it suitable for harder workpiece materials and more demanding cutting conditions. This blank arrives unground, ready for the end user to shape on a bench or surface grinder.\u003c\/p\u003e\n\u003cp\u003eSquare tool bit blanks are a standard stock item in machine shops, tool rooms, and maintenance departments. The 0.25-inch square shank fits a wide range of standard quick-change and lantern-style toolposts commonly found on engine lathes and manual turning centers. Machinists, tool and die makers, and maintenance technicians use blanks like this to fabricate custom cutting tools when off-the-shelf inserts or ground bits do not meet the required geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction provides elevated red hardness for cutting harder alloys\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 0.25 inches wide by 0.25 inches high for standard toolpost compatibility\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length gives adequate stock for grinding and re-grinding multiple tool profiles\u003c\/li\u003e\n  \u003cli\u003eUnground blank allows full custom geometry — rake, relief, nose radius ground to spec\u003c\/li\u003e\n  \u003cli\u003eConsistent material grade supports predictable grinding performance on standard bench grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-inch square tool bit blank suitable for use in toolposts and holders sized for 1\/4-inch square shank bits on manual engine lathes and similar turning equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding M42 cobalt HSS blanks requires a suitable aluminum oxide or CBN grinding wheel rated for HSS materials. Eye protection and proper ventilation are required during grinding operations. Ensure the tool bit is fully seated and clamped in the toolpost before initiating any cutting operation. Allow the workpiece and tool to reach thermal equilibrium before fine finishing cuts to maintain dimensional accuracy.\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\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 (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 460-6033\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720392671538,"sku":"460-6033","price":19.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe0ede1c9f7575df73cca756cd0fa6fc.jpg?v=1788563277","url":"https:\/\/voomisupply.com\/products\/value-collection-460-6033-tool-bit-blank-m42-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
