Manufactured from WKE45 cobalt high-speed steel, this blank offers elevated hot hardness and wear resistance compared to standard M2 HSS, making it well suited for interrupted cuts and difficult-to-machine materials. The blank measures 8 mm wide by 16 mm high with an overall length of 140 mm, providing sufficient stock for most lathe, boring, or broaching tool profiles. Licensed machinists, tool grinders, and maintenance technicians select this grade when a tool needs to hold an edge under elevated heat or impact.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in machine shops, maintenance departments, and job shops where custom tooling is ground to a specific profile. Typical applications include turning, facing, threading, and form tool production on manual and CNC lathes. The rectangular cross section suits standard tool holders and post-style tool blocks common on engine lathes and turret lathes. The WKE45 cobalt grade is a common choice when machining stainless steels, heat-resistant alloys, and hardened workpieces where standard HSS blanks wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWKE45 cobalt high-speed steel for improved hot hardness and edge retention over standard HSS grades\u003c\/li\u003e\n  \u003cli\u003eRectangular cross section at 8 mm wide by 16 mm high fits standard lathe tool holders and post blocks\u003c\/li\u003e\n  \u003cli\u003e140 mm overall length provides ample stock for grinding multiple tool profiles or regrinding worn tools\u003c\/li\u003e\n  \u003cli\u003eSolid blank construction allows full custom grinding to any cutting geometry\u003c\/li\u003e\n  \u003cli\u003eConsistent material grade supports repeatable tool performance across a production run\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard stock blank compatible with manual lathes, turret lathes, and tool grinders that accept 8 mm x 16 mm rectangular tool bit blanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks require grinding to final cutting geometry before use and should be shaped by a qualified tool grinder or machinist. Secure the blank firmly in a tool holder or grinding fixture before any machining or grinding operation to prevent movement. Wear appropriate eye protection and follow shop safety protocols when grinding cobalt HSS, as fine metallic particles are a hazard. Ensure the finished tool is properly seated and clamped in the tool post before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 mm (approximately 0.315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 16 mm (approximately 0.630 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 140 mm (approximately 5.51 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Rectangle\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63002167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558018548018,"sku":"63002167","price":70.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c92976eeeb4aa5fddadf6b32650c6ce.jpg?v=1786400998","url":"https:\/\/voomisupply.com\/products\/seco-63002167-tool-bit-blank-wke45-cobalt-rectangle","provider":"Voomi Supply","version":"1.0","type":"link"}
