Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials with greater heat resistance than standard HSS tooling. The 1-inch diameter cutter features 3 flutes with a high-helix, right-hand cutting and flute geometry, producing fast chip evacuation and reduced cutting pressure. With a 4-inch length of cut and 6.5-inch overall length, it provides extended reach for deeper pocketing and slotting operations on vertical and horizontal milling machines and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for production and job-shop environments where stock removal rate is the priority over finish quality. The bright, uncoated surface finish makes tool wear easy to monitor during service. Center-cutting capability allows plunge entry without a pre-drilled start hole, simplifying setups. The 1-inch shank diameter matches standard collet and end mill holder sizes common in knee mills, CNC vertical machining centers, and manual bridgeport-style machines. It is intended for installation and use by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for increased heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e3-flute, high-helix geometry for aggressive chip evacuation and fast stock removal\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows easy visual inspection of cutting edge condition\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 4-inch length of cut for deep pocketing and slotting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement roughing end mill for standard 1-inch collet chucks, end mill holders, and hydraulic tool holders used in knee mills, bridgeport-style machines, and CNC vertical machining centers requiring a 1-inch shank diameter tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Secure the shank to the full recommended engagement depth in the collet or holder to prevent tool pullout under cutting loads. Inspect cutting edges for chips or wear before each use and remove the tool from service if damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 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\u003eHelix Style\u003c\/strong\u003e: High\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 723-4580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720894710066,"sku":"723-4580","price":158.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2b937a46790bd1fffb45d28f77eef23.jpg?v=1788570642","url":"https:\/\/voomisupply.com\/products\/value-collection-723-4580-roughing-end-mill-1-in-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
