Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 4 mm wide by 4 mm high with an overall length of 100 mm. The cobalt alloy content improves heat resistance and edge retention compared to standard high-speed steel, making it well suited for interrupted cuts and harder workpiece materials. The blank arrives unground on the cutting end, giving the user full control over rake, relief, and nose radius.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank fits applications in manual lathe work, boring operations, and custom single-point tooling setups where standard insert tooling is not practical. It is commonly used in toolrooms, job shops, and maintenance machining environments. The square cross-section suits standard tool holders and grinder fixtures designed for 4 mm blanks. Machinists working with stainless steel, hardened alloys, or high-temperature materials will benefit from the WKE45 grade selection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWKE45 cobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSquare end shape compatible with standard 4 mm tool-holder slots and grinder fixtures\u003c\/li\u003e\n  \u003cli\u003e100 mm overall length provides sufficient material for multiple regrinds\u003c\/li\u003e\n  \u003cli\u003eUnground cutting end allows custom geometry to be applied by the user\u003c\/li\u003e\n  \u003cli\u003eConsistent 4 mm x 4 mm cross-section for accurate seating in tool posts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style blank for use in standard 4 mm square tool bit holders and grinder fixtures used in manual turning and toolroom machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks require grinding by a qualified machinist or toolroom technician before use as a cutting tool. Use appropriate personal protective equipment including eye protection when grinding. Secure the blank firmly in a tool grinder fixture and dress the grinding wheel before shaping the cutting geometry. Inspect the finished tool for cracks or burns before mounting in a tool post.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 01343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559571292466,"sku":"01343","price":25.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8124161aca44f359a7dc49a90a672c6.jpg?v=1786435621","url":"https:\/\/voomisupply.com\/products\/seco-01343-tool-bit-blank-cobalt-wke45-square-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
