M42 cobalt HSS offers superior red hardness and wear resistance compared to standard M2 HSS, making it well suited for interrupted cuts, tough alloys, and high-heat applications. This blank arrives ground to close tolerances at 1\/2 inch wide, 1 inch high, and 8 inches in overall length, giving toolmakers a consistent, ready-to-grind starting stock. It is a single-piece unit packaged individually.\u003c\/p\u003e\u003cp\u003eThis tool bit blank is used in machine shops, tool rooms, and maintenance environments where operators profile custom cutting geometries to fit lathes, shapers, planers, and boring bars. The rectangular cross-section suits standard tool holders and lantern-style tool posts. M42 grade cobalt blanks are frequently selected for production work on stainless steel, high-nickel alloys, titanium, and hardened steels where standard HSS tools wear too quickly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for high red hardness and extended tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003eGround finish ensures dimensional accuracy and a consistent grinding starting point\u003c\/li\u003e\n\u003cli\u003eRectangle cross-section fits standard tool holders and lantern posts without modification\u003c\/li\u003e\n\u003cli\u003e8-inch overall length provides material for multiple regrind cycles or custom profile grinding\u003c\/li\u003e\n\u003cli\u003e1\/2 inch wide by 1 inch high cross-section suits common lathe and shaper tool post slots\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tool bit blank for use in lathes, shapers, planers, and boring bar setups that accept rectangular HSS tool stock in a 1\/2 inch by 1 inch cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding of tool bit blanks should be performed by a qualified toolmaker or machinist using appropriate bench or surface grinders fitted with aluminum oxide or CBN wheels rated for HSS. Wear eye protection and use proper wheel guards in accordance with ANSI B11 and OSHA grinding safety standards. Dress the wheel before profiling to ensure a true, consistent cutting edge. Allow the blank to cool during grinding to prevent drawing the temper of the cobalt steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches (203.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth in mm\u003c\/strong\u003e: 12.70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Rectangle\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C44652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51721455305010,"sku":"C44652","price":560.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72ad12918753f5d0c447084d3109fc03.jpg?v=1788577614","url":"https:\/\/voomisupply.com\/products\/cleveland-c44652-m42-cobalt-tool-bit-blank-1-2x1x8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
