The blank measures 0.157 inches wide, 0.630 inches high, and 6.299 inches in overall length. Manufactured from cobalt high-speed steel at the WKE45 grade, it delivers elevated heat resistance and wear performance compared to standard M2 HSS blanks. This uncoated, unground-edge blank is the starting point for single-point lathe tools, form tools, and special-profile cutters shaped to job-specific requirements.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is suited for machine shops, toolrooms, and maintenance departments that grind their own tooling. It is appropriate for turning, boring, and profiling operations on manual or CNC lathes where a custom cutting edge geometry is required. The rectangular cross-section makes it compatible with standard square tool holders and lantern-style post holders. It is typically selected for harder workpiece materials where cobalt-grade toughness and hot hardness are required over conventional HSS.\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\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section fits standard square tool holder pockets\u003c\/li\u003e\n\u003cli\u003e6.299-inch overall length provides ample stock for regrinding multiple times\u003c\/li\u003e\n\u003cli\u003eUnground edges allow the machinist to establish custom cutting geometry\u003c\/li\u003e\n\u003cli\u003eConsistent blank dimensions support repeatable tool setups\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 square-shank tool holders and lantern post holders that accept a 4 mm wide by 16 mm high rectangular bit profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks are ground to final geometry by a qualified machinist using a bench or surface grinder with an appropriate wheel for high-speed steel. Secure the blank firmly in a tool grinding fixture or vise before grinding to maintain accurate relief and rake angles. Follow shop safety practices for abrasive grinding, including eye protection and proper wheel guarding. Ensure the tool holder set screw is tightened to the holder manufacturer specification before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 mm (0.157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 16 mm (0.630 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 160 mm (6.299 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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 63001449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560101085490,"sku":"63001449","price":57.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfd1e42b58451a745fe2099f6f5d59ae.jpg?v=1786446534","url":"https:\/\/voomisupply.com\/products\/seco-63001449-tool-bit-blank-wke45-cobalt-rectangle","provider":"Voomi Supply","version":"1.0","type":"link"}
