Built from M42 cobalt high-speed steel with a bright uncoated finish, it delivers heat resistance and edge retention under demanding cutting conditions. The 3-flute geometry provides a balance between chip evacuation and surface contact, making it well suited for roughing passes where stock removal rate is the priority. With a 0.25 inch cutting diameter, a 1.375 inch length of cut, and a 0.375 inch shank, this tool fits standard end mill holders and collet chucks used in manual and CNC milling operations. Installation and use should be performed by machinists or tooling professionals familiar with speeds, feeds, and work-holding requirements for cobalt tooling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for roughing operations in mill and machining center applications. The high helix style promotes aggressive chip flow and reduces heat buildup during extended cuts. Right-hand cutting and right-hand flute direction make it compatible with conventional right-hand spindle setups. Its center-cutting capability allows plunge entry, giving the operator flexibility in toolpath strategy. Typical applications include slotting, profiling, and pocketing in steel, stainless, and similar materials where a rough surface finish is acceptable before a finishing pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance compared to standard M2 tooling\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip clearance and cut stability during roughing passes\u003c\/li\u003e\n  \u003cli\u003eHigh helix style promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use with or without cutting fluid across a broad range of materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 3\/8 inch end mill holders, collet chucks, or milling machine spindles configured for right-hand rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify that the shank is fully seated and properly torqued in the holder per the tool holder manufacturer specifications before engaging the workpiece. Consult applicable speeds and feeds charts for M42 cobalt tooling and the specific workpiece material before commencing any cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\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\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 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: 723-4412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701658845490,"sku":"723-4412","price":106.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10dc40560df05bd0bfb708b7bc811c7d.jpg?v=1788403266","url":"https:\/\/voomisupply.com\/products\/value-collection-723-4412-roughing-end-mill-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
