Built to Series HS standards, it features a 7\/16 inch (0.4375 inch) mill diameter, a 4-flute spiral configuration with a 38-degree helix angle, and an AlCrTiN coating that resists heat and wear in demanding cutting conditions. The corner radius measures 0.0200 inches, reducing stress concentration at the cutting edge and extending tool life in ferrous and hardened materials. Centercutting geometry allows plunge entry without a pre-drilled pilot hole. This end mill is installed and operated by machinists and tool-and-die professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThe 2500535 suits finish milling, profiling, and contouring operations in tool steels, alloy steels, stainless steels, and similar materials where a corner radius is specified to prevent edge chipping or to match part geometry. With a 7\/8 inch length of cut and 2-3\/4 inch overall length, it fits standard 7\/16 inch collets or end mill holders. The micrograin carbide substrate and variable index geometry help reduce chatter and improve chip evacuation during both roughing passes and finish cuts. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for extended tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate for rigidity and edge sharpness retention\u003c\/li\u003e\n\u003cli\u003e0.0200 inch corner radius reduces stress and prevents edge chipping\u003c\/li\u003e\n\u003cli\u003e4-flute, 38-degree variable index spiral geometry reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSingle-end construction with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 7\/16 inch shank end mill holders and collet chucks used in CNC machining centers and manual milling machines requiring a corner radius end mill with AlCrTiN coating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and locked out before loading or removing the end mill from the holder. Use a torque wrench and the holder manufacturer's specified procedure when tightening collet nuts or set screws to prevent tool pullout. Verify runout with a dial indicator after seating to confirm proper concentricity before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.75 inches x 0.88 inches x 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 2500535\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729587142962,"sku":"2500535","price":128.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52320456bc8ff8c99b4afea0b587cfad_047130bd-4f4d-43e0-8a0c-b2702771b4a2.jpg?v=1788706447","url":"https:\/\/voomisupply.com\/products\/accupro-2500535-corner-radius-end-mill-7-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
