Built to Series 102 specifications, this 3-flute cutter features a 3\/8 inch cutting diameter, a 7\/8 inch length of cut, and a corner radius ranging from 0.055 to 0.065 inches. A ZrN (zirconium nitride) coating reduces friction and improves wear resistance. The high-helix, right-hand cutting geometry promotes efficient chip evacuation. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual mills for profiling, slotting, and finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on ferrous and non-ferrous materials where a fine corner radius improves part strength and surface finish. The centercutting design allows plunge entry directly into the workpiece. Its coarse pitch and high helix angle make it a solid choice for roughing and semi-finishing passes in a shop or production environment. The regular length profile fits standard toolholders without extended-reach considerations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with 7\/8 inch length of cut for standard-depth milling\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.055 to 0.065 inches reduces stress risers at part corners\u003c\/li\u003e\n\u003cli\u003e3 flutes with high-helix, right-hand geometry for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eZrN coating improves surface hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide corner radius end mill for use in standard 3\/8 inch collet or end mill toolholders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3\/8 inch shank fully in the toolholder and torque the retention system per the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 102-02416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52103383384370,"sku":"102-02416","price":146.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56e139c774af2d616b8622387e52a0fb_d26cf967-eb7f-4acd-bfa9-35f7f14a583d.jpg?v=1790071157","url":"https:\/\/voomisupply.com\/products\/promax-102-02416-corner-radius-end-mill-3-8in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
