It features a 1\/2 inch cutting diameter, a 1-1\/2 inch length of cut, and a 0.03 inch corner radius that reduces stress concentrations at the tool tip and improves surface finish at the cut edge. With 2 flutes and a high helix spiral geometry, this end mill promotes efficient chip evacuation and smooth cutting action. It is a single-end, centercutting tool ground from submicron carbide grade, making it suitable for demanding roughing operations where edge toughness and dimensional consistency matter.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in non-ferrous metal machining, including aluminum, brass, copper, and similar materials. Its coarse pitch and high helix angle make it well suited for aggressive roughing passes where chip load and heat management are critical. The 4 inch overall length and straight-cylindrical 1\/2 inch shank fit standard end mill toolholders, making it a practical choice for vertical machining centers, CNC mills, and manual knee mills. It is used by machinists and toolroom professionals across production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for edge integrity in non-ferrous roughing\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces chipping and stress at the cutting edge\u003c\/li\u003e\n\u003cli\u003e2-flute, high helix spiral design promotes chip evacuation in gummy materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for non-ferrous applications where coating buildup is a concern\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders.

Power down and lock out the spindle before loading or removing the tool. Seat the shank fully in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut, as excessive runout accelerates tool wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inch (4.0000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00043 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3876394\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743984156978,"sku":"3876394","price":227.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a8a3fd65cfd79c0d3efcfc56b0991bb_d6c891f8-5ed3-430d-8258-27ac82c6c6d4.jpg?v=1788852398","url":"https:\/\/voomisupply.com\/products\/kennametal-3876394-corner-radius-end-mill-1-2-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
