Built on the HS series platform, it features a 1\/2 inch diameter, a 5\/8 inch length of cut, and an AlCrTiN coating that resists heat and wear at elevated cutting temperatures. The 38-degree helix angle and 5-flute geometry promote smooth chip evacuation and surface finish. A 0.060 inch corner radius reduces stress concentration at the cutting edge and extends tool life in demanding applications. This tool is center-cutting and configured for right-hand cutting and flute direction.\u003c\/p\u003e\u003cp\u003eThe 311604 is suited for profiling, contouring, and finishing passes in CNC machining centers and manual mills where a corner radius profile is required. Its micrograin solid carbide construction handles hardened steels, stainless alloys, and other difficult-to-machine materials. The variable index geometry helps reduce harmonic chatter during deep side-wall cuts. With a 1\/2 inch shank diameter and 2-1\/2 inch overall length, it fits standard ER and end mill holders found in most production environments. Single-end configuration means the tool is replaced rather than flipped when worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature wear resistance in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e5-flute, 38-degree helix for improved chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e0.060 inch corner radius reduces edge chipping and extends tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eVariable index geometry reduces chatter during profiling passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 1\/2 inch straight shank end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth and torque the retention nut per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning the cut cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 311604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737607635250,"sku":"311604","price":140.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97977c787cdd4d493bf7bf02c6b17164.jpg?v=1788791309","url":"https:\/\/voomisupply.com\/products\/accupro-311604-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
