It features a 5\/16-inch cutting diameter, a 3\/4-inch length of cut (LOC), and a corner radius range of 0.04 to 0.05 inches. The three-flute geometry with a high 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A ZrN (Zirconium Nitride) coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. This tool is centercutting, enabling plunge entry as well as conventional and climb milling. Installed by machinists and toolroom professionals in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for generating corner radii, slot milling, and contour work on precision components. The coarse pitch classification and regular length type make it appropriate for general-purpose roughing and finishing passes on workpieces requiring controlled corner geometry. The 5\/16-inch shank diameter allows direct mounting in standard collet chucks and end mill holders common to vertical and horizontal milling machines. Right-hand cutting and right-hand flute direction are standard for conventional CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.04 to 0.05 inches for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eThree-flute, high-helix (40-degree) design promotes chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 102 regular-length corner radius end mill with a 5\/16-inch shank, compatible with standard collet chucks and end mill holders accepting 5\/16-inch diameter shanks on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and machine power is off before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder and torque the drawbar or clamping nut to the equipment manufacturer specification. Verify runout with a dial indicator before beginning the 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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3\/4 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\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.04 to 0.05 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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.06 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: 102-02016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52125179576626,"sku":"102-02016","price":128.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56e139c774af2d616b8622387e52a0fb_d041df86-9957-4b74-bd45-e3c824259a40.jpg?v=1790087401","url":"https:\/\/voomisupply.com\/products\/promax-102-02016-corner-radius-end-mill-5-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
