Built from M42 cobalt high-speed steel with a bright, uncoated finish, it carries a 7\/16-inch (0.4375-inch) cutting diameter and a 3\/8-inch shank diameter. The 1-inch length of cut and 2-11\/16-inch overall length make it well suited for shallow-to-moderate depth passes in ferrous and non-ferrous metals. With three flutes and a high-helix, right-hand cutting geometry, this tool breaks chips efficiently and reduces heat buildup during roughing passes. Licensed machinists and toolroom professionals install and operate this end mill on manual or CNC vertical milling machines.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is intended for stock removal on steels, stainless alloys, and similar materials where a standard end mill would chatter or deflect under load. The three-flute design balances chip evacuation with core strength, making it appropriate for side milling, slotting, and profiling operations where surface finish is secondary to material removal rate. Its centercutting capability allows plunge entry, adding versatility in production and job-shop environments. The compact overall length reduces overhang and improves rigidity at the spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003e3-flute, high-helix geometry promotes efficient chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle use\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids across a broad range of materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/8-inch straight shank for common collet and end mill holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank roughing end mill compatible with 3\/8-inch collets, end mill holders, and milling chucks used on vertical milling machines and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and locked out before loading or removing the end mill from its holder. Verify collet or holder bore matches the 3\/8-inch shank diameter and that the tool is seated to the full depth of the holder before tightening. Inspect the cutting edges for chips or damage before each use, as cobalt tooling can fracture under interrupted cuts if an edge is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.4375 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 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.3750 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 723-4445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689193374002,"sku":"723-4445","price":32.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4761352d6dec56aca050039d22a06ad.jpg?v=1788255974","url":"https:\/\/voomisupply.com\/products\/value-collection-723-4445-roughing-end-mill-7-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
