Built from M42 cobalt high-speed steel with a bright\/uncoated finish, it handles tough ferrous and non-ferrous materials where standard HSS tooling wears quickly. The 1\/2 inch diameter, 3-flute configuration balances chip clearance with cutting rigidity, making it well-suited for roughing passes that require fast stock removal before finishing. The right-hand cutting and right-hand flute direction are standard for conventional milling setups. A high helix style promotes efficient chip evacuation and reduces heat buildup at the cutting edge during heavy cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual mills, CNC machining centers, and knee mills for roughing operations on steel, stainless, cast iron, and similar materials. The centercutting geometry allows plunge milling when the application requires it. With a 5\/8 inch length of cut and 2-5\/8 inch overall length, it fits standard tool holders and collet chucks accepting a 1\/2 inch shank. It is appropriate for job shops, tool rooms, maintenance machining, and production environments where a reliable roughing tool is needed at a practical price point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip evacuation and cutting strength during roughing\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eHigh helix style promotes chip flow and reduces heat at the cutting edge\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids or dry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard roughing end mill for use in any mill or machining center equipped with a tool holder or collet chuck accepting a 1\/2 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with end mill setup and machine operation. Secure the shank fully in a collet chuck or end mill holder and confirm runout before beginning a cut. Ensure the machine spindle is at a full stop before changing or adjusting tooling. Follow the machine manufacturer guidelines and applicable shop safety protocols when setting speeds and feeds for cobalt end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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: 0.31 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: 723-4451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709925818674,"sku":"723-4451","price":40.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0e6844253f3d5dc8437bbe7a0017509.jpg?v=1788462365","url":"https:\/\/voomisupply.com\/products\/value-collection-723-4451-roughing-end-mill-1-2-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
