Measuring 5\/8 inches wide by 5\/8 inches high with an overall length of 4.5 inches, this blank provides substantial stock for single-point lathe tools, boring bars, fly cutters, and other custom-ground tooling. WKE45 cobalt grade offers elevated hot hardness compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and interrupted cutting conditions where heat resistance is critical.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, maintenance facilities, and toolrooms wherever custom-ground single-point tooling is required. It is appropriate for manual and CNC lathes, shapers, and planers. The square cross-section fits standard tool holders and lantern-style tool posts common in general-purpose turning operations. Machinists and tool grinders working with stainless steel, cast iron, or other demanding materials will find the cobalt grade a reliable choice over conventional HSS blanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWKE45 cobalt high-speed steel grade for improved hot hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eSquare cross-section at 5\/8 inches by 5\/8 inches for compatibility with standard tool holders\u003c\/li\u003e\n\u003cli\u003e4.5-inch overall length provides ample stock for grinding multiple profiles\u003c\/li\u003e\n\u003cli\u003eUnground blank format allows machinists to grind any custom cutting geometry\u003c\/li\u003e\n\u003cli\u003eSuitable for turning harder and more demanding workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square tool bit blank for use with tool holders and lantern-style tool posts that accept 5\/8-inch square shanks on manual and CNC turning equipment.\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 grinder or surface grinder with an appropriate wheel. Ensure the grinding wheel is rated for high-speed steel before use. Secure the blank firmly in a tool grinding fixture or vise to maintain consistent relief and rake angles during grinding. Always wear appropriate eye protection and follow shop safety procedures when grinding cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 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: 02017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560092205362,"sku":"02017","price":65.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0fbac99d07112a9c586f0f58feb2b5c.jpg?v=1786446366","url":"https:\/\/voomisupply.com\/products\/seco-02017-tool-bit-blank-5-8-in-square-cobalt-wke45","provider":"Voomi Supply","version":"1.0","type":"link"}
