With a 7\/16 inch diameter and a 0.060 inch corner radius, it produces a controlled edge break or blend radius on machined features while reducing stress concentrations at part corners. The four-flute, right-hand spiral design with a 38-degree variable index helix promotes efficient chip evacuation and stable cutting at higher feed rates. An AlCrTiN coating provides heat and wear resistance suited to dry or minimal-lubricant machining environments. This tool is installed and operated by machinists and CNC tooling professionals in job shop and production settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and profiling operations where a consistent corner radius is required. The centercutting geometry allows plunge entry, giving programmers flexibility in toolpath strategies without a separate drill operation. The straight cylindrical shank at 7\/16 inch diameter fits standard ER and set-screw style collet holders commonly used on vertical machining centers and CNC mills. It is appropriate for use in aluminum, stainless steel, tool steel, and other materials where an AlCrTiN coating provides coating-to-material compatibility.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for hardness and edge retention in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating for elevated heat resistance and extended tool life in dry or semi-dry machining\u003c\/li\u003e\n  \u003cli\u003e0.060 inch corner radius reduces stress risers and produces consistent blended edges\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes smooth chip flow and improved surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for standard 7\/16 inch straight cylindrical collet holders and set-screw tool holders on vertical machining centers and CNC milling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and in an e-stop or locked-out state before tool changes. Ensure the shank is fully seated and clean in the collet or holder before torquing to the holder manufacturer specification. Do not exceed the tool's rated depth of cut or chip load for the workpiece material. Inspect the cutting edges and corner radius for wear or chipping before each use to avoid surface finish defects or part damage.\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 inch (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: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (63.5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.002 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eVariable Index\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\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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 95170104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747819323698,"sku":"95170104","price":120.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/416be3be78d6663d5ce09f19074ce3c6_8fc38f0f-3683-4f40-be28-df11a70d79ee.jpg?v=1788885856","url":"https:\/\/voomisupply.com\/products\/accupro-95170104-corner-radius-end-mill-7-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
