It features a 1\/2-inch mill diameter with a 0.0300-inch corner radius, producing controlled edge geometry that reduces chipping and extends tool life at the cutting corner. The AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, making it well-suited for dry or semi-dry machining. With four flutes in a right-hand spiral configuration and centercutting capability, this tool handles both peripheral and plunge cuts. It is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal machining centers, CNC mills, and manual knee mills equipped with appropriate collet or end mill holders. The 1\/2-inch shank diameter fits standard ER32, ER40, and similar collet systems. The 5\/8-inch length of cut and 4-inch overall length make it appropriate for moderate-depth profiling, slotting, and contouring passes. The extended reach design, with a 2-3\/8-inch reach length and 0.450-inch neck diameter, allows access to features with tighter clearance requirements without tool deflection becoming a primary concern at conservative feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300-inch corner radius reduces stress concentration at the cutting edge and improves surface finish on profiled walls\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high thermal resistance for dry and semi-dry cutting in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate offers rigidity and wear resistance compared to high-speed steel tooling\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design balances chip evacuation with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtended reach with 2-3\/8-inch reach length and reduced 0.450-inch neck diameter for access to deeper features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production end mill for CNC machining center spindles accepting a 1\/2-inch shank diameter.

Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before inserting or removing the end mill. Inspect the shank and collet bore for chips, burrs, or runout before tightening. Follow the machine tool builder guidelines and applicable shop safety standards for tool clamping torque and runout verification before beginning a cut.\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\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 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\u003eNeck Diameter\u003c\/strong\u003e: 0.450 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.375 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\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\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\u003eVariable Helix\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: 0.5 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: 95168443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737262620978,"sku":"95168443","price":254.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022e5c9563f909da0ee7d065cf108202_a9995d8e-e814-4195-bdcd-2f0a196579e2.jpg?v=1788786340","url":"https:\/\/voomisupply.com\/products\/accupro-95168443-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
