With a 3\/8 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length, this single-end mill delivers consistent performance in CNC machining centers and manual milling operations. The 2-flute, right-hand spiral geometry with a high helix angle promotes efficient chip evacuation, making it well-suited for roughing passes in aluminum, brass, copper, and similar non-ferrous materials. The bright\/uncoated finish and submicron carbide grade support sharp edge retention where coatings are not required or preferred.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard straight-cylindrical shank toolholders with a 3\/8 inch bore and is rated for use with HC 20M through HC 32M hydraulic sleeves with inch bores. It is center-cutting, allowing plunge entry as well as conventional peripheral and slot milling. The Series AADF designation places it within a specific KENNAMETAL product family engineered for coarse-pitch, high-helix roughing of non-ferrous workpiece materials in production and job-shop environments. It is appropriate for machining operations performed by CNC operators, tool and die machinists, and precision machine shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grade construction for edge strength and wear resistance in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003eCorner radius end type reduces stress concentration at the cutting corner and extends tool life\u003c\/li\u003e\n  \u003cli\u003eHigh helix, coarse-pitch, 2-flute design promotes chip clearance during aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suited for non-ferrous metals where coating adhesion or contamination is a concern\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with HC 20M through HC 32M hydraulic sleeves metric with inch bores.

Ensure the shank is fully seated and clamped to the minimum engagement depth required by the toolholder manufacturer before beginning a cut. Do not exceed the toolholder rated runout tolerance, as excessive runout accelerates corner wear on carbide end mills. Verify workpiece fixturing rigidity before initiating roughing passes.\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 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\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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 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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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 \/ -0.000350 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: AADF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 12.4 x 1.2 x 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: 3876374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753893626162,"sku":"3876374","price":137.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddac2ff3863c4559f465164f80fc9100_93276aa9-c6b1-4020-b6c9-7818725f5a6a.jpg?v=1788941866","url":"https:\/\/voomisupply.com\/products\/kennametal-3876374-corner-radius-end-mill-3-8-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
