Designed for use in manual and CNC lathe toolholders, it serves as raw stock that machinists grind to a custom cutting profile for turning, facing, and boring operations. The blank measures 0.5 inches wide by 0.5 inches high with an overall length of 8 inches, giving the operator generous material to work with when forming and sharpening a tool geometry to suit a specific application. WKE45 cobalt HSS offers elevated heat resistance and edge retention compared to standard M2 HSS, making it well suited to interrupted cuts and harder workpiece materials.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is intended for machine shops, toolrooms, and maintenance operations where custom ground tooling is required. It is a common choice for apprentice and journeyman machinists who need to form a specific nose radius, relief angle, or rake geometry that is not available in a pre-ground insert system. The square cross-section fits standard right-hand toolholders and lantern-style post holders commonly found on engine lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel for improved hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eSquare cross-section at 0.5 inches x 0.5 inches fits standard lathe toolholders\u003c\/li\u003e\n\u003cli\u003e8-inch overall length provides ample stock for multiple grinds over the tool life\u003c\/li\u003e\n\u003cli\u003eUnground blank allows the operator to form any custom cutting geometry\u003c\/li\u003e\n\u003cli\u003eConsistent material grade throughout the blank supports uniform grinding response\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style blank for use in standard square-shank lathe toolholders and lantern-style tool posts that accept 0.5-inch square tool bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding tool bit blanks is typically performed by a machinist using a bench or pedestal grinder fitted with an appropriate aluminum oxide or CBN wheel. Eye protection and proper wheel guards are required at all times during grinding. The workpiece should be secured firmly and presented to the wheel at controlled angles to achieve consistent relief and rake geometry. Consult applicable shop safety standards before grinding operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 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: WKE45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07665\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558087229746,"sku":"07665","price":93.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1d200bf076d7d9246d3e6cb9b58ee0a.jpg?v=1786403003","url":"https:\/\/voomisupply.com\/products\/seco-07665-tool-bit-blank-wke45-cobalt-0-5x0-5x8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
