Measuring 5\/16 inches wide by 5\/16 inches high with a 6-inch overall length, this blank provides the raw stock machinists and tool grinders need to create custom single-point cutting tools, form tools, and special-profile lathe tools. The cobalt alloy composition delivers higher red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. No cutting edge is pre-ground; the end shape is square, ready for custom grinding to the desired geometry.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, maintenance facilities, and toolroom environments where standard off-the-shelf insert geometry does not meet the required profile. Machinists grind it to fit engine lathes, turret lathes, and manual boring applications. It is a common choice when working with stainless steel, titanium, heat-resistant alloys, and other materials that generate high cutting temperatures. The 6-inch length provides adequate stock for multiple regrinds over the life of the blank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45-grade cobalt high-speed steel for elevated red hardness and extended tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003eSquare end shape provides a neutral starting geometry for custom single-point or form-tool grinding\u003c\/li\u003e\n\u003cli\u003e5\/16 inch by 5\/16 inch cross-section fits standard tool holders and boring bar setups of that shank size\u003c\/li\u003e\n\u003cli\u003e6-inch overall length yields multiple regrinds before the blank is consumed\u003c\/li\u003e\n\u003cli\u003eSolid blank construction with no pre-ground relief angles, giving full control over final geometry\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 5\/16-inch tool holders and grinding fixtures on engine lathes and manual turning equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding this blank to a finished cutting tool requires a bench or tool-and-cutter grinder equipped with an aluminum oxide or CBN wheel appropriate for cobalt high-speed steel. Ensure the grinder rest is set securely and the blank is held firmly to maintain consistent relief and rake angles. Eye protection and a face shield are required during grinding operations. Follow shop safety procedures for heat management; avoid overheating the cutting edge during grinding, as excessive heat can reduce the hardness of the cobalt alloy.\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: 6 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: 05125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558975144242,"sku":"05125","price":39.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd7c51f6bc5b22a27195e74f0cfee076.jpg?v=1786424554","url":"https:\/\/voomisupply.com\/products\/seco-05125-tool-bit-blank-5-16-in-square-cobalt-6-in-oal","provider":"Voomi Supply","version":"1.0","type":"link"}
