Built from M42 cobalt high-speed steel and finished with a TiN coating, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 3-flute geometry at 3\/8 inch diameter provides a balance of chip clearance and rigidity, making it well suited for roughing passes that require fast stock removal with reduced chatter. Right-hand cutting and right-hand flute direction with a high helix style help evacuate chips efficiently. Centercutting capability allows plunge entry without a pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual mills and CNC machining centers for roughing operations on steel, stainless, cast iron, and similar hard materials. The 3\/8 inch shank fits standard ER collets, end mill holders, and Weldon-style tool holders common in job shop and maintenance machining environments. The 1.625 inch length of cut suits shallow-to-mid-depth pocketing and profiling. It is a practical choice for tool-and-die, maintenance machining, and general fabrication work where cobalt tooling extends tool life over standard HSS.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved hardness and heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip evacuation and core strength at 3\/8 inch diameter\u003c\/li\u003e\n\u003cli\u003eHigh helix, right-hand cut for efficient chip removal and smooth surface finish on roughing passes\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration; 1.625 inch length of cut and 3.1875 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch shank single-end roughing end mill compatible with ER collet chucks, end mill holders, and Weldon-style holders accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the recommended gauge line and tighten to the holder manufacturer torque specification. Inspect the TiN coating and cutting edges for chips or wear before each use; a damaged edge on a roughing end mill can cause workpiece chatter and premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 724-6442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693745799474,"sku":"724-6442","price":43.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fab295e22da5ad7742d0832e59cb124f.jpg?v=1788316860","url":"https:\/\/voomisupply.com\/products\/value-collection-724-6442-roughing-end-mill-3-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
