It features a 3\/16 inch diameter with a 0.010 inch corner radius that reduces stress concentration at the tool path edge, extending tool life in hard-material cuts. The three-flute geometry balances chip evacuation with rigidity, and the 35-degree helix angle promotes smooth cutting action. An AlTiN coating provides thermal resistance at elevated cutting temperatures, making this tool well-suited for ferrous and hardened materials. Licensed machinists and CNC programmers use this tool for finish profiling, slotting, and contour work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills for light-to-medium milling operations on steel, stainless steel, cast iron, and similar ferrous alloys where a corner break or blend radius is required on the finished part. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled starting hole. The 3\/8 inch length of cut and 2 inch overall length suit shallow-to-moderate depth pockets and profiles in production and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-temperature performance on ferrous and hardened workpieces\u003c\/li\u003e\n  \u003cli\u003e0.010 inch corner radius reduces edge chipping and produces a blended corner on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eThree-flute design balances chip clearance and tool body strength\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle promotes smooth, low-vibration cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting single-end configuration allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with ER or straight-shank collet systems accepting a 3\/16 inch shank diameter.

Secure the shank in a properly sized collet or end mill holder, ensuring full engagement depth per the holder manufacturer recommendation. Confirm spindle speed and feed rate are set per the material and coating manufacturer guidelines before cutting. Inspect the collet and holder for runout before use, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.010 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: 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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\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: 0.03 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: 106-01224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52000492945714,"sku":"106-01224","price":60.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f004fbe8cae600469ac522b833d1aa2.jpg?v=1789996451","url":"https:\/\/voomisupply.com\/products\/promax-106-01224-corner-radius-end-mill-3-16in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
