It features a 1\/2-inch mill diameter, a 2-inch length of cut, and a 60-degree helix angle that promotes aggressive chip evacuation and smooth cutting action. The TiCN (titanium carbonitride) coating adds surface hardness and heat resistance, extending tool life in demanding cutting conditions. With three flutes and a right-hand cutting and flute direction, this end mill suits a wide range of profiling, slotting, and peripheral milling operations. It is a single-end, non-chipbreaker design with a micrograin carbide grade for enhanced edge retention.\u003c\/p\u003e\u003cp\u003eThis end mill is used in machine shops, tool rooms, and production environments where long-reach milling is required. The long-length configuration, with a 4-inch overall length and a 1\/2-inch shank diameter, suits deeper cavity work and setups where standard-length tools cannot reach. It is center-cutting, allowing plunge entry. Machinists running CNC machining centers, knee mills, or manual milling machines use this tool for steel, stainless, cast iron, and similar materials where TiCN coating provides a performance advantage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces tool wear in abrasive materials\u003c\/li\u003e\n\u003cli\u003e60-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eLong-length configuration with 2-inch LOC and 4-inch OAL for extended-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/2-inch ER or straight-shank tool holders used in CNC machining centers and manual milling machines requiring a long-length, 3-flute square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the shank in a collet or end mill holder to the manufacturer-recommended pull-out force for your toolholder system before operating. Verify spindle speed and feed rate parameters against material-specific cutting data before engaging the cut. Inspect the cutting edges for chipping or wear before each use and do not operate a damaged tool.\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 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747641655602,"sku":"2500250","price":195.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62c1cd6ea36e5b229f8c917adea2e2e4.jpg?v=1788883950","url":"https:\/\/voomisupply.com\/products\/accupro-2500250-square-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
