Built with a 1\/2 inch diameter and a 0.030 inch corner radius, it reduces stress concentrations at the cutting edge and extends part finish quality in demanding materials. The 4-flute, right-hand spiral configuration with a 38-degree helix promotes efficient chip evacuation and smooth cutting action. An AlCrTiN coating provides thermal and oxidation resistance, making this tool well-suited for high-speed and dry machining environments. It is a single-end, centercutting tool, meaning it can plunge as well as profile. Machinists and CNC operators in job shops and production facilities are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for extended-reach applications, with a 2.25 inch reach length and a reduced neck diameter of 0.475 inches, allowing access to deep pockets and complex workpiece geometries without sacrificing rigidity where the shank supports the cut. The 5\/8 inch length of cut and 4 inch overall length make it appropriate for profiling, slotting, and finishing passes on ferrous and non-ferrous workpieces. The variable index flute spacing helps dampen vibration during high-feed operations, contributing to improved surface finish and reduced chatter in production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.030 inch corner radius reduces edge chipping and stress risers on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating provides high thermal resistance for dry or minimal-lubrication machining\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 2.25 inch reach length and reduced 0.475 inch neck diameter for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eVariable index flute geometry minimizes chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers hardness and wear resistance across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool compatible with standard 1\/2 inch shank toolholders including ER collet chucks, end mill holders, and shrink-fit systems used in CNC machining centers.\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 in an E-stop or locked-out state before changing tooling. Seat the 1\/2 inch shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning a production run, as excessive runout will accelerate wear on a 4-flute carbide tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 310893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746179907890,"sku":"310893","price":189.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9041189b46110e58bd8735c3c148b4b9.jpg?v=1788866820","url":"https:\/\/voomisupply.com\/products\/accupro-310893-corner-radius-end-mill-1-2-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
