It features a 7\/16-inch (0.4375-inch) mill diameter, a 1-inch length of cut, and a 5-flute configuration that improves chip evacuation and surface finish at higher feed rates. The 45-degree helix angle reduces cutting forces and promotes smooth entry into the workpiece. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. This is a single-end, right-hand cutting tool manufactured from micrograin solid carbide.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for peripheral and slot milling operations in job shops, tool rooms, and production machining environments. The regular-length geometry and 7\/16-inch shank diameter make it compatible with standard ER and side-lock toolholders on vertical and horizontal machining centers as well as CNC knee mills. It is center-cutting, allowing plunge entry where required. Machinists and CNC operators working in steel, stainless, cast iron, and similar materials will find this tool appropriate for finishing and semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute design increases feed rate capability and improves surface finish compared to 4-flute tools\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand helix reduces axial cutting forces and improves chip flow\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides elevated hardness and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and edge retention in demanding cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches ensures accurate feature sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank solid carbide square end mill for use in 7\/16-inch collet chucks, ER collet systems, and side-lock toolholders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (2.75 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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 2500409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731064226098,"sku":"2500409","price":114.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8e468a10112b22833b1b0ec4fe752d0.jpg?v=1788726472","url":"https:\/\/voomisupply.com\/products\/accupro-2500409-square-end-mill-7-16-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
