It features a 5\/8 inch diameter with a 0.03 inch corner radius and a 1-1\/4 inch length of cut, making it well suited for profiling, contouring, and slotting where a blended edge radius is required to reduce stress concentration. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating improves heat resistance and extends tool life in high-temperature cutting environments. This is a single-end, centercutting tool, allowing direct plunge entry into the workpiece. It is intended for use by machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for milling steel, stainless steel, cast iron, and similar materials where AlTiN coating performance is an advantage. The centercutting geometry supports both peripheral milling and plunge operations. With a 5\/8 inch shank diameter and 3-1\/2 inch overall length, it fits standard ER or side-lock toolholders used on vertical machining centers and CNC milling machines. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces edge chipping and stress concentration on workpiece corners\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry for efficient material removal and surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/8 inch ER collet chucks, side-lock holders, or hydraulic toolholders on CNC vertical and horizontal machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully to the recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and avoid premature tool wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 12182642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728107241778,"sku":"12182642","price":164.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6e0f991202351bf3e86094b71d7f000.jpg?v=1788688096","url":"https:\/\/voomisupply.com\/products\/accupro-12182642-corner-radius-end-mill-5-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
