It features a 0.0312 inch cutting diameter with a 0.01 inch corner radius that blends the floor and wall of a cut to reduce stress concentrations and improve surface finish. The flute length (LOC) is 0.093 inches, with a measured length of cut of 0.4724 inches, and an overall length of 1.5 inches on a 0.125 inch shank. The AlTiN coating provides excellent heat resistance and hardness at elevated cutting temperatures, making this tool well suited for hardened steels, stainless, and high-temp alloys. Licensed machinists and CNC tool-room technicians are the primary installers and operators of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers, CNC mills, and high-speed micro-milling operations where a small-diameter, corner-radiused tool profile is required. It is particularly applicable in die and mold work, medical component machining, and precision part production where floor radii, slot profiles, or contoured surfaces must be held to tight tolerances. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling within the miniature series range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0312 inch cutting diameter with 0.01 inch corner radius for precise radius blending on floors and walls\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high heat resistance, improved tool life in ferrous and exotic alloy cutting\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration 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\u003eRight-hand cut, right-hand spiral with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature series corner radius end mill compatible with standard 0.125 inch shank collets and tool holders used in CNC machining centers and high-speed micro-milling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe, locked-out state. Use a calibrated collet or shrink-fit holder rated for the 0.125 inch shank diameter to ensure minimal runout. Verify tool projection and reach against the programmed toolpath before cycle start. At this diameter, excessive side load or improper feed rates significantly increase breakage risk — confirm feeds and speeds against the material being cut before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.093 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasured Length of Cut\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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: 30 degrees\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 14796289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728382230834,"sku":"14796289","price":51.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff58368f92a326d81ef88f4f9dc3a9c2.jpg?v=1788690796","url":"https:\/\/voomisupply.com\/products\/accupro-14796289-corner-radius-end-mill-0-0312in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
