It features a 3\/8-inch diameter cutting head with a 0.03-inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in slotting and peripheral milling operations. The 3-flute, right-hand spiral geometry provides efficient chip evacuation at high helix angles. With a short flute length of 3\/4 inch and a straight cylindrical shank, this single-end, centercutting tool is suited for CNC machining centers and manual mills where controlled material removal in aluminum, brass, copper, and similar non-ferrous workpieces is required. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for roughing operations in non-ferrous metals, identified by material code N. The short length-of-cut geometry minimizes deflection during aggressive cuts. The coarse pitch and high helix style promote chip flow away from the cut zone, making this tool well suited for pocketing, profiling, and slot milling in aluminum alloys and similar materials. It is also noted as compatible for use with HC-HSK Form A toolholding systems, giving it a direct application in HSK-equipped machining centers where runout and rigidity are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide grade for wear resistance in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius reduces edge chipping and improves surface finish at workpiece corners\u003c\/li\u003e\n  \u003cli\u003e3-flute right-hand spiral with high helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup risk when machining aluminum or other soft non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with tight shank diameter tolerance for secure collet or chuck clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with HC-HSK Form A toolholding systems.

The machine spindle must be fully stopped and the tool-change mode engaged before loading or removing the end mill from the collet or toolholder. Verify runout with a dial indicator after clamping to confirm seating within acceptable limits. Follow the machine manufacturer and tooling manufacturer feed-and-speed recommendations for the specific workpiece material and depth of cut before running production.\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 inches (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: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle Style\u003c\/strong\u003e: High (38 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ABDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3660425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753191014706,"sku":"3660425","price":122.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51ecc93fa5c79c1c7b8cbd38dda7bdbe_cef3338b-26ae-4fa7-9295-8b979c74e449.jpg?v=1788933692","url":"https:\/\/voomisupply.com\/products\/kennametal-3660425-corner-radius-end-mill-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
