The cutter measures 1\/4 inch in diameter with a 0.03 inch corner radius, a 3\/8 inch length of cut, and a 2 inch overall length. Three right-hand spiral flutes with a high helix angle and coarse pitch promote efficient chip evacuation and smooth cutting action. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is a single-end, center-cutting design built from submicron solid carbide for rigidity and edge retention at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and roughing operations in non-ferrous metals such as aluminum, copper, and brass. The AADE series short-length geometry is well matched to CNC machining centers where a compact tool overhang reduces deflection. The 1\/4 inch straight cylindrical shank fits standard collet chucks and hydraulic toolholders. Compatible hydraulic sleeve toolholders include the HC 20M through HC 32M Hydraulic Sleeves Metric with Inch Bores and the HC-CV Form AD.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration at the tool-workpiece interface and extends edge life\u003c\/li\u003e\n\u003cli\u003eThree right-hand spiral flutes with high helix angle for efficient chip removal in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade provides consistent hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish optimized for non-ferrous metal cutting where reactive coatings are unnecessary\u003c\/li\u003e\n\u003cli\u003eShort overall length of 2 inches minimizes tool deflection in tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with HC 20M through HC 32M Hydraulic Sleeves Metric with Inch Bores and the HC-CV Form AD toolholding systems.

Power down and lock out the machine spindle before installing or removing the tool. Ensure the shank is fully seated and clamped to the specified collet torque per the toolholder manufacturer guidelines. Verify runout with a dial indicator before initiating the first cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (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\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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 Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADE\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 3658816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739754365234,"sku":"3658816","price":94.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dc924105dae23d87ca947c9192419b5_404c5a47-af4d-473c-a7d9-bcf40bc5159e.jpg?v=1788818523","url":"https:\/\/voomisupply.com\/products\/kennametal-3658816-corner-radius-end-mill-1-4-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
