Manufactured from WKE45 grade cobalt high-speed steel, this blank measures 10mm wide by 12mm high with a 200mm overall length. It arrives unground, allowing machinists and tool grinders to profile the cutting geometry to match a specific operation. The WKE45 cobalt grade provides elevated hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for intermittent cuts and harder workpiece materials.\u003c\/p\u003e\u003cp\u003eRectangle tool bit blanks of this type are used in machine shops, tool rooms, and production environments where lathe, planer, or shaper tooling must be custom ground. They are commonly used to create single-point turning tools, threading tools, form tools, and other special-profile cutters. Installation is performed by professional machinists or tool grinders working with surface grinders, tool and cutter grinders, or bench grinders equipped with appropriate grinding wheels for high-speed steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel grade for improved hot hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eRectangle cross-section at 10mm wide by 12mm high for versatile tool grinding profiles\u003c\/li\u003e\n\u003cli\u003e200mm overall length provides ample stock for grinding multiple tool geometries\u003c\/li\u003e\n\u003cli\u003eSupplied unground, ready for custom profiling to specific cutting applications\u003c\/li\u003e\n\u003cli\u003eSolid cobalt construction throughout the full blank cross-section\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose rectangle tool bit blank suitable for use in standard tool holders and grinder setups that accept metric-dimensioned high-speed steel blanks of this cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding of tool bit blanks should be performed by qualified machinists using grinding wheels rated for cobalt high-speed steel. Wear appropriate eye protection and ensure grinding equipment guards are in place before starting. Allow the blank and grinding wheel to cool periodically to prevent overheating, which can soften the cutting edge. Always verify ground tool geometry with appropriate gauging before mounting in a tool holder for production use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eWidth\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 200mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 63002121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560011792690,"sku":"63002121","price":85.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdea854a79996a00cb4d4660b635a622.jpg?v=1786445356","url":"https:\/\/voomisupply.com\/products\/seco-63002121-rectangle-tool-bit-blank-cobalt-wke45","provider":"Voomi Supply","version":"1.0","type":"link"}
