Manufactured from WKE45-grade cobalt high-speed steel, this blank measures 5 mm in width, 5 mm in height, and 100 mm in overall length. Tool bit blanks of this type are purchased unground and then precision-ground by the end user or tool grinder to a specific cutting geometry. Licensed machinists, tool and die makers, and CNC tool grinders are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis blank is suited for shops that require custom-profiled cutting tools for turning, threading, form cutting, or other specialized lathe and grinder operations. The cobalt WKE45 material grade offers elevated heat resistance and wear resistance compared to standard M2 high-speed steel, making it appropriate for harder workpiece materials and higher cutting speeds. It is sold individually and is compatible with standard tool holders and grinder setups that accept 5 mm square shank blanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRound end shape provides a starting profile for custom tool grinding\u003c\/li\u003e\n\u003cli\u003e5 mm x 5 mm cross-section fits standard small-shank tool holders\u003c\/li\u003e\n\u003cli\u003e100 mm overall length provides sufficient stock for grinding multiple tool profiles over the blank's service life\u003c\/li\u003e\n\u003cli\u003eSold as a single-piece unit with no minimum order beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or aftermarket blank for use in standard tool grinding and custom cutting tool fabrication applications requiring a 5 mm square cobalt high-speed steel bit blank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks are ground to final geometry by a qualified tool grinder or machinist using appropriate surface or tool and cutter grinding equipment. Secure the blank firmly in the grinder's work-holding fixture before grinding to prevent movement. Eye protection and appropriate guards must be used in accordance with shop safety standards. Do not attempt to use an unground blank as a cutting tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5 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: Round\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: 02078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561549332786,"sku":"02078","price":25.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cee4cd8e343815b558221c8dbfd5183.jpg?v=1786465451","url":"https:\/\/voomisupply.com\/products\/seco-02078-tool-bit-blank-cobalt-wke45-round-5mm-x-100mm","provider":"Voomi Supply","version":"1.0","type":"link"}
