Measuring 5\/16 inches wide by 5\/16 inches high with an overall length of 2.5 inches, this blank provides the raw stock machinists and tool grinders need to create custom single-point cutting tools, form tools, and lathe bits. WKE45 cobalt HSS offers elevated red hardness and wear resistance compared to standard M2 HSS, making it a practical choice for interrupted cuts, tough alloys, and applications where tool life under heat is a priority.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is suited for use in machine shops, tool rooms, and maintenance facilities where operators grind their own tooling profiles to match specific turning, boring, or facing operations. The square cross-section allows the blank to be held securely in standard tool holders and ground on any face to achieve the required rake, relief, and nose geometry. It is appropriate for manual lathes, turret lathes, and similar single-point tooling setups in both production and jobbing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel for improved red hardness and extended tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003eSquare cross-section for consistent seating in standard tool bit holders and grinding fixtures\u003c\/li\u003e\n\u003cli\u003e5\/16 inches x 5\/16 inches cross-section accommodates common small-to-medium lathe tool post sizes\u003c\/li\u003e\n\u003cli\u003e2.5 inches overall length provides sufficient stock for multiple grinds over the tool life\u003c\/li\u003e\n\u003cli\u003eUnground blank format allows custom geometry to be applied by the end user\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square tool bit blank for use in manual lathes, turret lathes, and single-point tooling applications requiring a 5\/16-inch tool bit size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench or pedestal grinder equipped with appropriate grinding wheels for high-speed steel. Eye protection and proper wheel guards must be used during grinding operations. Ensure the tool is seated fully and clamped securely in the tool post or holder before initiating a cut. Allow the tool to cool adequately between heavy grinding passes to avoid thermal damage to the cutting edge.\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: 2.5 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: Square\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: 02005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559836123442,"sku":"02005","price":20.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9c71a76c64998dfb25b4b4d642c06e.jpg?v=1786442379","url":"https:\/\/voomisupply.com\/products\/seco-02005-cobalt-tool-bit-blank-5-16-in-wke45-square","provider":"Voomi Supply","version":"1.0","type":"link"}
