Built to Series AADE specifications, this single-end, centercutting tool features a 3\/16 inch (0.1875 inch) mill diameter, a 5\/16 inch (0.3125 inch) length of cut, and a 3-inch overall length. The 37-degree high helix angle promotes efficient chip evacuation in aluminum, brass, copper, and similar materials. The submicron carbide grade delivers edge integrity under demanding cutting conditions. This tool is intended for use by machinists and CNC operators in job shop, production, and tool room environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for short-reach roughing and finishing passes on non-ferrous workpieces where corner radius geometry is required to reduce stress concentration at part edges. The bright\/uncoated finish makes it appropriate for aluminum and other materials where coated tools can cause built-up edge. The straight-cylindrical shank is compatible with hydraulic and collet-style toolholding systems. Typical applications include contouring, slotting, and profiling operations on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron grade construction for edge retention in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCorner radius end type reduces stress risers and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003e37-degree high helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral, coarse pitch — 3-flute configuration balances chip room and rigidity\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish optimized for non-ferrous metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with HC 1\/2 through HC 1 1\/4 hydraulic sleeves (inch bore, inch shank), HC 20M through HC 32M hydraulic sleeves (metric sleeve, inch shank bore), and ER single angle standard collets.

Secure the shank fully within the toolholder to the manufacturer-recommended gage line depth before tightening. Power down and lock out the machine spindle before changing tooling. Verify runout with a dial indicator after installation to protect edge life and part dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\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\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees (High)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron Carbide\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.049 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: 3870448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729078550834,"sku":"3870448","price":76.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eec930b09e62f2fe41c968c36ea14a0_4b76792f-44b9-4d98-ab90-5f443b4864c9.jpg?v=1788699633","url":"https:\/\/voomisupply.com\/products\/kennametal-3870448-corner-radius-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
