It features a 3\/8 inch cutting diameter, a 7\/8 inch length of cut, and a corner radius range of 0.055 to 0.065 inches. The 4-flute, right-hand cutting geometry with a 30-degree helix angle improves chip evacuation and surface finish in a range of ferrous and non-ferrous materials. An AlTiN coating extends tool life under high-heat cutting conditions. This tool is centercutting, allowing plunge entry. It is installed and operated by machinists and CNC programmers in production and tool-and-die environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for profile milling, slotting, and contouring applications where a small edge radius is required to reduce stress concentrations and chipping at part corners. The coarse pitch and right-hand flute direction make it appropriate for general-purpose machining of steel, stainless steel, and hardened alloys. The 3\/8 inch shank diameter fits standard ER collets and end mill holders. The 2-1\/2 inch overall length provides adequate reach for most standard workpiece setups without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch cutting diameter with 0.055 to 0.065 inch corner radius range\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut and right-hand helix at 30 degrees\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch classification for chip clearance in demanding cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new installation for 3\/8 inch shank end mill holders and ER collet chucks used in CNC machining centers and manual knee mills requiring corner radius tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using an appropriate end mill holder or collet chuck sized for a 3\/8 inch shank. The spindle must be fully stopped and the machine locked out before changing tooling. Verify runout with a dial indicator after seating to confirm proper tool engagement. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.055 to 0.065 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100-02414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52044065898802,"sku":"100-02414","price":146.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88124bc9f666bf1157093aee236fe3cc.jpg?v=1790029570","url":"https:\/\/voomisupply.com\/products\/promax-100-02414-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
