It features a 1\/2-inch cutting diameter, a 0.0100-inch corner radius, and four right-hand spiral flutes with a variable helix for improved chip evacuation and reduced chatter. The AlTiN coating provides high heat resistance and extended tool life when cutting ferrous materials and hardened steels. This is a single-end, centercutting tool, meaning it can be used for plunging as well as peripheral and slot milling. It is sized in the stub length category, making it well-suited for rigid setups where overhang must be minimized.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use by machinists and tool-and-die professionals working on CNC machining centers and manual mills. Stub-length corner radius end mills are commonly applied in die and mold work, finishing passes on hardened steel cavities, and contour milling where a controlled radius at the cutting edge is required to blend surfaces or avoid sharp corners. The 5\/8-inch length of cut and 1\/2-inch shank diameter make this tool a direct fit for standard ER or set-screw toolholders with a 1\/2-inch bore.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated thermal resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e0.0100-inch corner radius reduces stress concentration and extends edge life compared to sharp-corner end mills\u003c\/li\u003e\n\u003cli\u003eVariable helix flute geometry minimizes harmonic vibration and chatter during cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute orientation compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/2-inch bore toolholders including ER collet chucks, hydraulic holders, and set-screw holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Verify collet bore and shank diameter match before seating the tool, and confirm tool stick-out is minimized to maintain rigidity. Always confirm spindle rotation direction matches the right-hand cutting direction of this tool before engaging the workpiece.\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\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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: 95168257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727180595506,"sku":"95168257","price":167.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2165629752ff09820f63f53c6a968fcc.jpg?v=1788674400","url":"https:\/\/voomisupply.com\/products\/accupro-95168257-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
