The tool features a 3\/8 inch diameter, a 7\/8 inch length of cut, and a 0.02 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding cuts. A TiCN coating provides increased surface hardness and lubricity compared to uncoated carbide, making it well suited for ferrous and non-ferrous materials at elevated feed rates. Micrograin carbide construction supports tight tolerances and consistent edge integrity across the tool's service life. This end mill is installed and operated by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 106-02412 is used in vertical and horizontal milling operations where a corner radius profile is required to blend floor-to-wall transitions in pockets, slots, and contoured surfaces. With a 35-degree helix angle and right-hand cutting direction, it performs well in both roughing and finishing passes on steel, stainless, cast iron, and aluminum. The single-end, centercutting design allows plunge entry and versatile toolpath programming on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02 inch corner radius reduces edge chipping and stress risers at pocket floors\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and heat dissipation during high-speed cuts\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate maintains edge sharpness under heavy loads\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 106 OEM-style corner radius end mill suitable for standard 3\/8 inch tool holders, collets, and end mill adapters used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the 3\/8 inch shank fully in a clean, undamaged collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Inspect the cutting edges for chips or coating damage before first use, and verify runout with an indicator before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (1.0000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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: TiCN\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 Spiral\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002000 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\u003eSeries\u003c\/strong\u003e: 106\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: 106-02412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52023565648178,"sku":"106-02412","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1027c5ea71fc5a94d3d56daf221e54f1.jpg?v=1790014127","url":"https:\/\/voomisupply.com\/products\/promax-106-02412-corner-radius-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
