It features a 3\/16 inch diameter with a 0.015 inch corner radius, reducing stress concentrations at the cutting edge and extending tool life compared to a sharp-corner geometry. The 4-flute, right-hand spiral configuration delivers efficient chip evacuation and a smooth surface finish. An AlTiN+ coating provides high-temperature hardness and oxidation resistance, making this tool well-suited for dry or semi-dry cutting environments. Machinists and toolroom operators working in job shops, aerospace, and precision manufacturing will find this a reliable single-end cutting solution.\u003c\/p\u003e\u003cp\u003eThis end mill is applied in CNC milling operations where a controlled corner radius is required on internal profiles, pockets, and contoured features. The centercutting design allows for direct plunge entry, adding versatility across finishing and semi-finishing passes. The regular-length 5\/8 inch length of cut and 2 inch overall length make it appropriate for standard reach applications in vertical machining centers and CNC mills. Its micrograin carbide substrate supports use in harder workpiece materials where edge retention is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch corner radius reduces edge chipping and improves part surface finish on radiused features\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers elevated hot hardness and oxidation resistance for demanding dry-cut applications\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with right-hand cutting direction for compatibility with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides superior rigidity and edge retention over high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank sized at 3\/16 inch for standard collet and end mill holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard collets or end mill holders accepting a 3\/16 inch straight-cylindrical shank.

Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Secure the shank to the full recommended engagement depth in the collet or holder to prevent pullout under cutting loads. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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: AlTiN+\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6\/44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 14556366\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755126587698,"sku":"14556366","price":63.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87c39aac4447b463f7b0ee2262b9aeea.jpg?v=1788951404","url":"https:\/\/voomisupply.com\/products\/accupro-14556366-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
