It measures 3\/8 inches wide by 3\/8 inches high with an overall length of 3 inches (76.20 mm). Tool bit blanks in this grade are used by machinists and tool grinders to create custom single-point cutting tools, form tools, and specialty inserts. M42 cobalt provides higher heat resistance and hardness retention compared to standard M2 high-speed steel, making it suitable for interrupted cuts and harder workpiece materials. The ground finish ensures consistent dimensions straight from the package, reducing prep time at the grinder.\u003c\/p\u003e\n\u003cp\u003eThis blank is suited for use in manual and CNC lathes, boring bars, and custom toolholders where a shop-ground cutting edge is required. It is commonly used in job shops, tool rooms, and maintenance machining environments where off-the-shelf insert geometries do not meet the application. Machinists working with stainless steel, titanium, and other difficult-to-machine alloys frequently choose M42 cobalt blanks for their improved wear resistance at elevated cutting temperatures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 3\/8 inches x 3\/8 inches for use in standard toolholders\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length provides sufficient stock for grinding multiple edge profiles\u003c\/li\u003e\n  \u003cli\u003eGround finish ensures dimensional consistency and reduces blank preparation time\u003c\/li\u003e\n  \u003cli\u003eSquare end shape compatible with standard lathe and boring bar tool seats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a shop-ground tool bit blank for use in standard 3\/8-inch toolholders on manual lathes, CNC turning centers, and boring setups requiring custom ground cutting tool profiles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTool bit blanks are ground to a final cutting geometry by a qualified machinist or tool grinder using appropriate bench or surface grinding equipment. Secure the blank firmly in a tool grinding fixture before grinding to maintain correct angles and avoid chatter. Always use eye protection and follow shop safety procedures when grinding high-speed steel. Verify the finished tool geometry and clearance angles match the intended workpiece material and operation before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.20 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\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: C44547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694617264434,"sku":"C44547","price":68.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f961f214f876f3ad9410b56dc673bd0.jpg?v=1788326351","url":"https:\/\/voomisupply.com\/products\/cleveland-c44547-m42-cobalt-tool-bit-blank-3-8-x-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
