Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 3\/8 inches wide by 1\/2 inches high with a 3-inch overall length. WKE45 cobalt HSS delivers elevated red-hardness and wear resistance compared to standard M2 HSS, making it suitable for interrupted cuts, tough alloys, and applications where tool life under heat is a priority.\u003c\/p\u003e\u003cp\u003eThis blank is used in general metalworking, toolroom, and maintenance machining environments. It is appropriate for lathe work, shaper operations, and any application requiring a custom-ground single-point or form tool. The rectangular cross-section suits standard tool holders and lantern-style post setups common on engine lathes. Machinists and tool grinders working in job shops, production facilities, or maintenance departments will find this blank a practical starting point for specialty tooling needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel for superior red-hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section at 3\/8 inches wide by 1\/2 inches high for standard toolholder fitment\u003c\/li\u003e\n\u003cli\u003e3-inch overall length provides sufficient material for grinding multiple profiles or resharpening\u003c\/li\u003e\n\u003cli\u003eUnground cutting geometry allows full customization by the end user\u003c\/li\u003e\n\u003cli\u003eSuitable for machining tough alloys, stainless, and materials prone to work hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tool bit blank for use in standard lathe tool posts, shaper tool heads, and custom toolholder setups accepting 3\/8-inch by 1\/2-inch rectangular blanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding of this blank should be performed by a qualified machinist or tool grinder using appropriate wheel grades for high-speed steel. Eye protection and a properly dressed grinding wheel are required. Follow shop safety procedures for tool grinding, including adequate wheel guarding and coolant use where applicable. Ensure the finished tool geometry matches the requirements of the intended cutting operation before mounting in the tool holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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: Rectangle\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: 63007901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558938673458,"sku":"63007901","price":43.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ab03c9330401db642cc49e9b0c07d2.jpg?v=1786423477","url":"https:\/\/voomisupply.com\/products\/seco-63007901-cobalt-tool-bit-blank-3-8x1-2x3-in-wke45","provider":"Voomi Supply","version":"1.0","type":"link"}
