It is an unground, ready-to-shape blank used by machinists and toolroom technicians to grind custom single-point lathe tools, form tools, and special-purpose cutting tools. The blank measures 0.25 inches wide by 0.25 inches high with a 6-inch overall length. M42 cobalt steel offers higher red-hardness than standard M2 high-speed steel, making it well suited for interrupted cuts and harder work materials where heat buildup at the cutting edge is a concern.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in manual and CNC lathe toolroom applications where a technician needs to grind a custom profile rather than use an indexable insert. Typical applications include one-off form tools, threading tools, and specialty boring tools ground to a specific geometry. The square cross-section allows for mounting in standard square-pocket tool holders and Armstrong-style holders common in manual lathe setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS material grade for improved red-hardness and wear resistance over standard M2\u003c\/li\u003e\n\u003cli\u003eSquare cross-section at 0.25 inches wide by 0.25 inches high for compatibility with standard square-pocket holders\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides ample stock for grinding and re-grinding multiple tools\u003c\/li\u003e\n\u003cli\u003eUnground blank allows the technician to grind any custom cutting geometry as needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square tool bit blank for use in Armstrong-style and equivalent square-pocket single-point tool holders accepting a 0.25-inch cross-section bit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool bit blanks are ground to final geometry using a bench grinder or surface grinder with an appropriate abrasive wheel rated for high-speed steel. Always use eye protection and ensure the grinder tool rest is properly set before grinding. Inspect the finished cutting edge for cracks or irregularities before mounting in a tool holder. Secure the ground bit firmly in the holder and verify tool height before taking a cut.\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: 6 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: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 460-6160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692052218162,"sku":"460-6160","price":41.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/faa87831ca345c2bb88c72e1f191651c.jpg?v=1788292425","url":"https:\/\/voomisupply.com\/products\/value-collection-460-6160-m42-cobalt-tool-bit-blank","provider":"Voomi Supply","version":"1.0","type":"link"}
