It features a 7\/16 inch (0.4375 inch) mill diameter, a 2 inch length of cut, and a 4 inch overall length, placing it in the long series category. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A titanium carbonitride (TiCN) coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous applications. Five flutes provide a balance of chip clearance and surface finish quality. Micrograin carbide substrate supports tighter tolerances and greater edge integrity compared to standard carbide grades. Licensed machinists and CNC tool-room technicians are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose and finish milling work on steel, stainless, cast iron, and similar materials in job shop, tool-and-die, and production machining environments. The long series length of cut makes it well suited for slotting and profiling operations where extra reach into a workpiece or fixture clearance is needed. The single-end, right-hand cutting and right-hand flute configuration is the standard orientation for conventional CNC machining centers and manual vertical mills. The centercutting geometry allows plunge milling where the application calls for it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16 inch mill diameter with a tolerance of +0.000 \/ -0.002 inches for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e2 inch length of cut in the long series range, suited for deep slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e5-flute spiral configuration balances chip evacuation with improved finish on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle reduces axial cutting forces and promotes smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eTiCN coating provides enhanced hardness and wear resistance over uncoated or TiN-coated tools\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers high rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge entry cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct procurement tool for standard 7\/16 inch collet or end mill holder setups on CNC machining centers and manual vertical mills requiring a long series, 5-flute square end mill with a 7\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and locked out before mounting or removing the tool from the holder. Use a properly sized collet or end mill holder that matches the 7\/16 inch shank diameter and confirm shank runout is within acceptable limits before beginning a cut. Verify tool projection and stick-out length against the programmed depth of cut to avoid deflection or chatter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: 7\/16 inches (0.4375 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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738714538290,"sku":"2500283","price":135.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e636900d658b3a2bc513316b0f759c7.jpg?v=1788803281","url":"https:\/\/voomisupply.com\/products\/accupro-2500283-square-end-mill-7-16-in-5-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
