Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers good heat and wear resistance in ferrous and non-ferrous machining applications. The 3\/8 inch diameter body carries 4 flutes with a right-hand cutting and flute direction, producing the characteristic serrated chip-splitting profile that reduces cutting forces and heat buildup during heavy roughing passes. With a 1.125 inch length of cut and a 2-15\/16 inch overall length, it suits standard vertical mills, knee mills, and CNC machining centers running roughing cycles.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for roughing operations where rapid stock removal is the priority before a finish pass is applied. The 3\/8 inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style side-lock holders commonly found in job shop and production environments. Its M42 cobalt construction makes it a practical choice when machining alloy steels, stainless, and other materials that generate elevated cutting temperatures. The non-centercutting design means it should be used for peripheral and slot milling entries from the side rather than plunge cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved heat resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003e4-flute roughing geometry reduces cutting forces and breaks chips during heavy passes\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for general-purpose roughing without coating overhead\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting — requires side entry or pre-drilled start hole for slot work\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; 3\/8 inch shank matches mill diameter for direct holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for 3\/8 inch end mill holders, ER collet systems, and side-lock holders used in vertical mills, knee mills, and CNC machining centers requiring a 3\/8 inch shank roughing end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is properly seated and torqued in the holder before running. Confirm shank engagement depth meets the holder manufacturer minimum before operation. Always verify spindle direction is set to right-hand rotation before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-5726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716053762354,"sku":"723-5726","price":61.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/438e574ea63acbe334f613b39cab0b72.jpg?v=1788521682","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5726-roughing-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
