It measures 0.25 inches wide by 0.25 inches high with an overall length of 4 inches. Tool bit blanks serve as unground starting stock that machinists and tool grinders shape into custom single-point lathe tools, form tools, and special-purpose cutting tools. The cobalt content in WKE45 increases hot hardness and wear resistance compared to standard M2 HSS, making this blank well-suited for grinding tools intended to cut difficult-to-machine alloys, stainless steels, and hardened materials. The square cross-section allows grinding on any face.\u003c\/p\u003e\u003cp\u003eThis blank is used in machine shops, tool rooms, and maintenance facilities wherever custom or replacement cutting tools are required. It is appropriate for use in manual lathes, turret lathes, and screw machines that accept 0.25-inch square tool holders. Machinists grind the blank to the required rake, relief, and nose geometry for the specific workpiece material and operation. The 4-inch overall length provides sufficient stock for multiple regrinds over the service life of the tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel for increased hot hardness and wear resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003eSquare cross-section at 0.25 inches by 0.25 inches for versatile grinding on any face\u003c\/li\u003e\n\u003cli\u003e4-inch overall length provides ample stock for initial grinding and subsequent resharpening\u003c\/li\u003e\n\u003cli\u003eUnground blank condition allows custom geometry to be applied by the end user\u003c\/li\u003e\n\u003cli\u003eConsistent dimensions support repeatable tool room production\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0.25-inch square tool bit blank compatible with tool holders and grinder fixtures that accept 0.25-inch square shank stock.\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 abrasive wheels for high-speed steel. Always wear eye protection and ensure the grinder rest is properly adjusted before grinding. Verify the finished tool geometry and clearance angles are appropriate for the workpiece material before mounting the tool in a lathe or holder. Allow the tool to cool periodically during grinding to prevent drawing the temper of the cobalt steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\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: 02003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563743084850,"sku":"02003","price":25.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f6b5f1d32a3ade965ed400aaf9444ef.jpg?v=1786502335","url":"https:\/\/voomisupply.com\/products\/seco-02003-tool-bit-blank-cobalt-square-wke45","provider":"Voomi Supply","version":"1.0","type":"link"}
