Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), this tool delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The 3-flute, right-hand cutting geometry with a high-helix flute direction promotes efficient chip evacuation and reduces chatter during roughing passes. Center-cutting capability allows plunge milling as well as conventional peripheral cuts. At 0.375 inches in diameter with a 0.4375-inch length of cut and a 2.1875-inch overall length, it suits tight-tolerance work in a variety of materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on manual knee mills, CNC machining centers, and benchtop mills where roughing passes precede finish milling. It is commonly applied to ferrous metals, alloy steels, and stainless steels where cobalt tooling outperforms standard HSS. Machinists, toolroom operators, and job shop technicians working in both production and prototype environments will find this a practical single-end roughing option for 3\/8-inch applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e3-flute, high-helix right-hand geometry promotes fast chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter matches standard collets and end mill holders\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration for straightforward tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct addition for standard 3\/8-inch end mill holders, ER collet chucks, and side-lock arbors used on manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians using an appropriate collet, end mill holder, or side-lock arbor sized for a 3\/8-inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify tool runout with a dial indicator after securing the end mill, and confirm cutting parameters are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches (2.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\u003eCenter Cutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 724-6430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711231689010,"sku":"724-6430","price":31.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/131a109f340c4e04a167e8b5a5d5d71a.jpg?v=1788475017","url":"https:\/\/voomisupply.com\/products\/value-collection-724-6430-roughing-end-mill-3-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
