Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 0.5 inches in width, 1.25 inches in height, and 7 inches in overall length. The cobalt alloy composition provides elevated heat and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. Machinists and tool grinders select this blank as the starting stock for lathe bits, form tools, and specialty cutters ground to specific profiles.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, toolrooms, and industrial production environments. It serves as raw stock for grinding single-point lathe tools, threading tools, boring bars, and other profiled cutting tools on a surface grinder or tool and cutter grinder. The rectangular cross-section and 7-inch overall length provide ample stock for multiple grinds or for fabricating longer tooling configurations. It is appropriate for both prototype toolmaking and short-run production setups where off-the-shelf insert tooling is not suitable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel construction for improved hot hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section simplifies mounting in standard tool holders and vises\u003c\/li\u003e\n\u003cli\u003e0.5 inches x 1.25 inches cross-section accommodates a range of tool holder sizes\u003c\/li\u003e\n\u003cli\u003e7-inch overall length provides sufficient stock for multiple grinds\u003c\/li\u003e\n\u003cli\u003eUnground blank format allows custom profile grinding to suit specific applications\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 rectangular tool holders and tool posts on engine lathes and similar machine tools where a 0.5-inch by 1.25-inch cross-section blank is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding and shaping of cobalt tool bit blanks is typically performed by a machinist or tool grinder using a surface grinder or bench grinder equipped with an appropriate grinding wheel rated for high-speed steel. Eye protection and grinding guards must be in place before grinding operations begin. Secure the blank firmly in a grinding vise or fixture to prevent movement during material removal. Allow the blank to cool periodically during grinding to avoid thermal damage to the cutting edge geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 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\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: 63007904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558224167218,"sku":"63007904","price":201.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c92976eeeb4aa5fddadf6b32650c6ce_71d5d2d7-e071-4cff-ae2a-f63787b7d7c7.jpg?v=1786406524","url":"https:\/\/voomisupply.com\/products\/seco-63007904-tool-bit-blank-wke45-cobalt-rectangle","provider":"Voomi Supply","version":"1.0","type":"link"}
