It features a 3\/8 inch diameter with a 0.015 inch corner radius and a 5\/8 inch length of cut, making it well suited for profiling, slotting, and peripheral milling where edge strength and surface finish are critical. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hard alloy cutting. With three right-hand spiral flutes and a centercutting geometry, this end mill handles both plunge entry and conventional milling paths. It is installed and operated by machinists and CNC tooling professionals in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use on CNC machining centers and manual mills cutting steel, stainless steel, cast iron, and high-temperature alloys where corner rounding on part features is required. The single-end design with a 3\/8 inch shank diameter fits standard ER and mechanical collet toolholding systems. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces in medium to high-feed applications. Micrograin carbide substrate provides rigidity and wear resistance in demanding production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentration at milled edges and improves part durability\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers high oxidation resistance and hardness for dry or minimal-lubrication cutting\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides superior rigidity and edge retention over tool steel alternatives\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eSingle-end construction with 3\/8 inch shank fits standard collet and endmill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool for use in standard 3\/8 inch collet or mechanical endmill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before engaging the workpiece, as excessive runout accelerates edge wear and degrades corner radius accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000200 to -0.000800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: 12179352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742417748274,"sku":"12179352","price":73.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a88dbdaefc66e59086ceeffdd343886.jpg?v=1788837326","url":"https:\/\/voomisupply.com\/products\/accupro-12179352-corner-radius-end-mill-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
