Manufactured from WKE45-grade cobalt high-speed steel, this blank serves as raw stock for machinists and toolmakers who grind custom cutting tool profiles to specific geometry requirements. The round end shape allows for flexible grinding in multiple orientations. WKE45 cobalt HSS delivers higher red hardness and heat resistance compared to standard M2 high-speed steel, making it suitable for cutting harder workpiece materials at elevated temperatures without losing edge integrity.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, tool rooms, and production environments where custom-ground single-point lathe tools, boring bars, or specialty form tools are required. It is appropriate for use on manual engine lathes, turret lathes, and manual milling setups. Machinists working with stainless steel, titanium, and other difficult-to-machine alloys often select cobalt blanks over standard HSS for their improved wear resistance and thermal stability under heavy cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45-grade cobalt high-speed steel for superior red hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003e5\/8-inch x 5\/8-inch cross section with 6-inch overall length for standard tool holder sizing\u003c\/li\u003e\n\u003cli\u003eRound end shape supports versatile custom grinding orientations\u003c\/li\u003e\n\u003cli\u003eSolid blank stock allows machinists to grind any cutting geometry to application-specific requirements\u003c\/li\u003e\n\u003cli\u003eSuitable for machining hard and difficult-to-cut materials including stainless and titanium alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose cobalt HSS tool bit blank for use in standard 5\/8-inch tool holders and grinding fixtures on manual lathes and milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding of tool bit blanks should be performed by qualified machinists using appropriate bench or surface grinders fitted with aluminum oxide or CBN wheels rated for high-speed steel. Always wear eye protection and use a tool rest when grinding. Ensure the workpiece is properly cooled during grinding to avoid overheating the cutting edge and degrading the cobalt alloy hardness. Finished tools should be inspected for geometry before installation in a tool holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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: Round\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: 05146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559025246514,"sku":"05146","price":92.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32f51102c905ce2f57e203ccc2c22f51.jpg?v=1786426057","url":"https:\/\/voomisupply.com\/products\/seco-05146-tool-bit-blank-5-8x5-8x6-in-wke45-cobalt-round","provider":"Voomi Supply","version":"1.0","type":"link"}
