Manufactured from WKE45-grade cobalt high-speed steel, this blank is supplied unground on the cutting end, allowing machinists and tool grinders to profile custom cutting geometries to suit a specific turning, boring, or form-tool application. The WKE45 cobalt grade offers elevated hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cuts where tool life is a priority.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is intended for use in manual lathes, turret lathes, and screw machines where the operator or tool room grinds their own tooling to a desired profile. It fits standard tool holders and tool posts sized for 5\/16 inch by 1\/2 inch shank blanks. Typical applications include single-point turning tools, threading tools, parting tools, and form tools produced in-house. Sold individually, this blank is appropriate for job shops, tool rooms, and maintenance machining environments where custom ground tooling is routinely required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel grade provides superior hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section at 5\/16 inch wide by 1\/2 inch high suits common tool post and holder slots\u003c\/li\u003e\n\u003cli\u003e6 inch overall length allows for multiple regrinds, extending the usable life of each blank\u003c\/li\u003e\n\u003cli\u003eUnground cutting end accepts custom profiles ground by the end user to match specific machining requirements\u003c\/li\u003e\n\u003cli\u003eSolid cobalt construction throughout — no brazed tip or insert — for consistent regrinding performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock blank for manual lathes, turret lathes, and screw machines accepting 5\/16 inch by 1\/2 inch rectangular tool bit blanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks must be ground to the required cutting geometry by a qualified machinist or tool grinder before use. Use appropriate personal protective equipment, including eye protection and heat-resistant gloves, when grinding cobalt high-speed steel. Ensure the grinding wheel is rated for high-speed steel materials and that the blank is kept cool during grinding to prevent annealing the cutting edge. Secure the ground tool properly in the tool post or holder before operating any lathe or machine tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/16 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 (OAL)\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: 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: 63006939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560187167026,"sku":"63006939","price":67.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6defec36ed57c30a3736d8a924b607a7.jpg?v=1786448660","url":"https:\/\/voomisupply.com\/products\/seco-63006939-cobalt-tool-bit-blank-5-16x1-2x6-inch-wke45","provider":"Voomi Supply","version":"1.0","type":"link"}
