It measures 5\/16 inches wide by 5\/16 inches high with an 8-inch overall length. Tool bit blanks are unground cutting tool stock used by machinists and tool grinders to fabricate custom lathe tools, form tools, and single-point cutters. The WKE45 cobalt grade offers increased heat resistance and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder work materials. Machinists and toolroom personnel grind these blanks to a specific geometry using a bench grinder or surface grinder before mounting in a tool holder.\u003c\/p\u003e\u003cp\u003eThis blank is used in toolroom environments wherever a custom cutting tool geometry is required. Common applications include fabricating turning tools, boring bars, threading tools, and fly cutter bits for manual and CNC lathes and mills. The square cross-section simplifies orientation in standard tool holders and quick-change toolposts. It is appropriate for both job shop and production toolroom use where standard insert tooling does not meet the required profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel grade for elevated hot hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eSquare cross-section at 5\/16 inches x 5\/16 inches for consistent tool holder fit\u003c\/li\u003e\n\u003cli\u003e8-inch overall length provides ample stock for grinding multiple tools or extended profiles\u003c\/li\u003e\n\u003cli\u003eUnground blank format allows full custom geometry for specialized cutting applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tool bit blank compatible with standard 5\/16-inch tool holders and quick-change toolpost blocks used on manual and CNC lathes and mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding and shaping of tool bit blanks should be performed by a qualified machinist or tool grinder using appropriate wheel grades for high-speed steel. Eye protection and proper wheel guards are required during grinding operations. Ensure the tool holder or toolpost is fully clamped and the machine spindle is locked before securing a finished tool. Follow applicable shop safety procedures when handling freshly ground tools, as edges are extremely sharp.\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\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\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: 02008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558859112754,"sku":"02008","price":61.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2cf4ba2c311d4aa85341490d18b446b.jpg?v=1786421012","url":"https:\/\/voomisupply.com\/products\/seco-02008-tool-bit-blank-5-16-x-8-inches-wke45-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
