With a 0.25-inch cutting diameter and 1.25-inch length of cut, this tool delivers tight tolerances and consistent results in ferrous and non-ferrous materials. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Featuring a bright, uncoated finish and Material Grade K600 carbide substrate, it is suited for high-speed cutting in shops where tool life and dimensional accuracy are priorities. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is built for single-end use in CNC machining centers, vertical mills, and manual knee mills. Its 0.25-inch shank diameter fits standard collet and end mill holder systems. The right-hand cut, right-hand spiral flute geometry makes it compatible with conventional and climb milling passes. The AADF series designation indicates this is a general-purpose geometry suited for slotting, profiling, and peripheral milling in a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with K600 material grade for wear resistance and rigidity\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip flow and reduced vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for non-ferrous and general-purpose applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral geometry\u003c\/li\u003e\n\u003cli\u003eAADF series with no chipbreaker and no variable helix for predictable cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for 0.25-inch collet chucks and end mill holders used in CNC and manual milling machines.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Use a properly sized collet or shrink-fit holder to maintain the shank diameter tolerance of +0.00000 to -0.00035 inches. Verify runout with a dial indicator before beginning a production run 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: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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: K600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Single\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\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 3658893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732560347442,"sku":"3658893","price":133.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e57af4413a442bfbbc36083ed0af7c8.jpg?v=1788744454","url":"https:\/\/voomisupply.com\/products\/kennametal-3658893-square-end-mill-0-25in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
