It measures 3\/4 inches wide by 3\/4 inches high with a 5-inch overall length. This blank is intended to be custom-ground by the end user into a specific cutting tool geometry — such as a turning, boring, or threading tool — for use in a lathe or similar machine tool. M42 cobalt HSS offers elevated heat and wear resistance compared to standard M2 HSS, making it well-suited for difficult-to-machine materials including stainless steel, titanium alloys, and hardened steels. The square cross-section and precision ground surfaces provide a consistent, ready-to-grind starting point for tool room applications.\u003c\/p\u003e\n\u003cp\u003eThis tool bit blank is used in metal machining environments where operators or tool grinders need to produce custom single-point or form tools. Typical applications include production turning, manual lathe work, and prototype tooling in job shops, maintenance facilities, and manufacturing plants. The 3\/4-inch square shank accommodates a range of standard tool holders and lantern-style lathe post setups commonly found on engine lathes. The 5-inch length gives sufficient stock for multiple resharpening cycles over the tool's service life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved red hardness and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 3\/4 inches by 3\/4 inches for compatibility with standard lathe tool holders\u003c\/li\u003e\n  \u003cli\u003e5-inch overall length provides ample stock for custom grinding and repeated resharpening\u003c\/li\u003e\n  \u003cli\u003ePrecision ground surfaces ensure accurate starting geometry before custom profiling\u003c\/li\u003e\n  \u003cli\u003e10-degree bevel angle ground into the blank for a ready-to-finish cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tool room blank suitable for use in engine lathes, turret lathes, and similar machine tool setups that accept 3\/4-inch square tool bit shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to final geometry by a qualified machinist or tool grinder using a bench or pedestal grinding wheel appropriate for high-speed steel. Ensure the grinding wheel is rated for HSS before use and dress the wheel prior to grinding. Secure the blank firmly in a tool grinding fixture or rest to maintain consistent relief and rake angles during shaping. Always wear eye protection and follow applicable shop safety practices during grinding operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eWidth\u003c\/strong\u003e: 3\/4 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGround or Unground\u003c\/strong\u003e: Ground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBevel Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C44556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695324397874,"sku":"C44556","price":315.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae76e550fb9d1e66e33d3996f86e2044.jpg?v=1788333909","url":"https:\/\/voomisupply.com\/products\/cleveland-c44556-tool-bit-blank-m42-cobalt-5-in-square","provider":"Voomi Supply","version":"1.0","type":"link"}
