Built to Series HS standards, this single-end tool features a 1\/4 inch mill diameter, a 3\/8 inch length of cut, and a 2 inch overall length. The AlCrTiN coating improves heat and oxidation resistance, making it well suited for cutting hardened steels, stainless alloys, and high-temp materials at elevated speeds. With 5 flutes and a variable index geometry, this end mill delivers smooth chip evacuation and reduced chatter across a range of cutting conditions. It is center cutting and accepts direct plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where a corner radius profile is required to reduce stress concentrations at the base of a milled feature. The 0.020 inch corner radius adds edge strength and produces a blended fillet in the floor-to-wall transition of a slot or pocket. Right-hand flute direction and right-hand cutting orientation are standard for conventional spindle setups. The straight cylindrical shank with 1\/4 inch diameter fits standard ER collet chucks and end mill holders commonly found in shop environments. Machinists, tool-and-die makers, and CNC programmers working in aerospace, mold making, and general precision machining will find this tool appropriate for finish and semi-finish passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating for heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e5-flute variable index design reduces harmonic vibration and chatter during cuts\u003c\/li\u003e\n  \u003cli\u003e0.020 inch corner radius strengthens cutting edge and produces a fillet at slot and pocket floors\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCenter cutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry assists chip control during deeper passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill compatible with standard 1\/4 inch ER collet chucks, end mill holders, and milling chucks used in CNC machining centers and knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to maximize tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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: 3\/8 inch (0.3750 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: 0.020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 95169790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730914246962,"sku":"95169790","price":69.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6661e01a9c052ce8dd17cbc6e71842f1.jpg?v=1788724718","url":"https:\/\/voomisupply.com\/products\/accupro-95169790-corner-radius-end-mill-1-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
