It features a 1\/4-inch cutting diameter with a 0.0600-inch corner radius that blends radial and end cutting edges, reducing stress concentrations and improving surface finish on workpiece corners. The 4-flute configuration with a variable helix and right-hand spiral flute geometry balances chip evacuation with rigidity. An AlTiN coating provides thermal and wear resistance for high-speed cutting in ferrous and hardened materials. This tool is sold as a single-end, centercutting end mill with a stub-length flute, suited for machinists and tool-and-die professionals running CNC mills or manual milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for light-to-medium roughing and finishing passes in steel, stainless steel, cast iron, and other hard alloys where corner radius geometry is required to maintain edge integrity. Its stub-length flute design prioritizes rigidity over reach, making it well suited for short-reach pockets, slots, and profiling operations. The 1\/4-inch shank diameter fits standard ER collets and end mill holders commonly found in vertical machining centers and CNC routers. Machinists working in job shops, aerospace component manufacturing, and mold-and-die applications will find this geometry useful for controlled finishing passes at the bottom of cavities and along vertical walls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0600-inch corner radius reduces stress at cutting edges and improves workpiece surface finish\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate provides hardness and edge retention beyond standard carbide grades\u003c\/li\u003e\n\u003cli\u003eAlTiN coating delivers high-temperature oxidation resistance for dry or semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003eVariable helix geometry reduces chatter and harmonics during milling passes\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n\u003cli\u003eStub flute length maximizes tool rigidity in short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/4-inch shank end mill holders and ER collet chucks on CNC vertical machining centers and manual milling machines requiring a 4-flute corner radius end mill with a 1\/4-inch cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the 1\/4-inch shank fully into the collet or end mill holder and torque the retention nut to the tool-holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\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\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\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.05 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: 95168457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744766984498,"sku":"95168457","price":82.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d65c5132d96ae60c12ec0b6df17dae70.jpg?v=1788860300","url":"https:\/\/voomisupply.com\/products\/accupro-95168457-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
