It measures 5\/8 inches wide by 5\/8 inches high with an overall length of 4.5 inches. Tool bit blanks are unformed cutting stock that machinists grind to a custom profile for use in lathe toolholders, boring bars, and single-point cutting applications. M42 cobalt steel offers elevated heat resistance and hardness retention compared to standard M2 HSS, making it a reliable choice for interrupted cuts and harder workpiece materials. The ground finish provides dimensional accuracy straight from the package, reducing bench time before use.\u003c\/p\u003e\n\u003cp\u003eThis blank is suited for job shops, tool rooms, and production machining environments where custom-ground tooling is required. Machinists use blanks like the C44553 when a standard insert or brazed tool geometry does not match the required profile, such as for form tools, threading tools, or specialty boring operations. The square cross-section fits standard square-shank toolholders common on engine lathes and manual mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel for improved hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eSquare ground cross-section at 5\/8 inches by 5\/8 inches for consistent fit in standard toolholders\u003c\/li\u003e\n  \u003cli\u003e4.5-inch overall length provides ample stock for grinding multiple tool profiles\u003c\/li\u003e\n  \u003cli\u003eGround finish ensures dimensional accuracy and reduces setup time at the bench grinder\u003c\/li\u003e\n  \u003cli\u003eSquare end shape ready for custom profile grinding by the end user\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-profile replacement or raw stock blank for square-shank toolholders accepting 5\/8-inch bit stock, typical on engine lathes and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to shape by a machinist using a bench or tool grinder before installation in a lathe or mill toolholder. Secure the blank firmly in the toolholder and verify proper relief and rake angles before cutting. Eye protection and appropriate grinding wheels rated for cobalt HSS are required during the grinding process. Follow your shop safety procedures and any applicable OSHA guidelines when operating grinding equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 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: M42\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\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: C44553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711811649842,"sku":"C44553","price":203.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a27dee5e2614b65cdd9c68d8249ed96.jpg?v=1788479885","url":"https:\/\/voomisupply.com\/products\/cleveland-c44553-tool-bit-blank-5-8in-square-m42-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
