It runs a 3\/8 inch diameter with a 0.0200 inch corner radius and a 5\/8 inch length of cut. The three-flute geometry and 35-degree helix angle promote efficient chip evacuation while maintaining surface finish quality. Centercutting capability allows plunge entry. This tool is suited for machinists and tool-and-die professionals working in production or job-shop environments on ferrous and hardened materials.\u003c\/p\u003e\n\u003cp\u003eThe 106-02424 is used in CNC milling operations where a controlled corner radius is required to reduce stress concentrations in part features such as pockets, slots, and profiled edges. The AlTiN coating supports dry or minimal-lubrication cutting in harder alloys and stainless steels. With a 3\/8 inch shank diameter matching the cutter diameter, it seats directly in standard ER or end mill holders without a reduction collet. It is a Series 106 tool from PROMAX, intended for right-hand cutting with right-hand flute direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance and extended tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius reduces stress concentrations and workpiece edge breakout\u003c\/li\u003e\n  \u003cli\u003e3-flute, 35-degree helix design for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cut and right-hand spiral flutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8 inch end mill holders or ER collet chucks on CNC machining centers and manual mills requiring a corner radius end mill in the Series 106 configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3\/8 inch shank fully into the holder and torque the retention hardware to the tool-holder specification. Verify runout with a dial indicator before committing to a production cut, as excessive runout accelerates carbide wear and degrades corner radius accuracy.\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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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 \/ -0.002000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 106\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 106-02424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51972579033394,"sku":"106-02424","price":93.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dff2365a0d8f304b3bdbb4f3a9bd8199.jpg?v=1789969872","url":"https:\/\/voomisupply.com\/products\/promax-106-02424-corner-radius-end-mill-3-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
