It features a 7\/16-inch mill diameter, a 7\/8-inch length of cut, and a 2-3\/4-inch overall length. The four-flute, right-hand spiral geometry paired with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlCrTiN coating provides thermal and oxidation resistance, extending tool life in high-speed and dry-cutting environments. The corner radius measures 0.0600 inches, reducing stress concentration at cutting edges and improving edge strength on profiled cuts. This end mill is centercutting, allowing direct plunge entry without a pre-drilled pilot hole. Machinists and tool-and-die professionals install and run this tool on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits milling operations that require a defined corner radius on vertical walls, slots, and profiled pockets. It is well suited for use in aerospace, mold-and-die, and precision machining applications where corner integrity and tight tolerances are critical. The variable index geometry helps reduce harmonic chatter during full-slot and side-milling passes. The straight cylindrical shank with a 7\/16-inch shank diameter fits standard ER and end mill holders. Single-end configuration means the cutting geometry is on one end only, and the tool is not reversible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating for high-temperature resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.0600-inch corner radius reduces edge chipping and improves surface finish at floor-to-wall transitions\u003c\/li\u003e\n  \u003cli\u003e4-flute, 38-degree variable-index spiral geometry reduces chatter and supports higher feed rates\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 7\/16-inch straight-bore end mill holders, ER collet chucks, and shrink-fit tooling on CNC vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists using standard end mill holders or collet chucks rated for the 7\/16-inch shank diameter. Ensure the holder bore and collet are clean and free of burrs before seating the tool. Power down the spindle and confirm the machine is in a safe state before changing tooling. Follow the tool manufacturer and machine builder guidelines for runout tolerances and pull-out prevention when setting tool stick-out.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (69.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00200 to -0.00200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 95170107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747524051250,"sku":"95170107","price":124.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a1c154de4c248653f694f211ae5e487.jpg?v=1788881877","url":"https:\/\/voomisupply.com\/products\/accupro-95170107-corner-radius-end-mill-7-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
