Built to the AADE series specification, it features a 0.25-inch mill diameter, a 0.375-inch length of cut, and a three-flute spiral configuration with a 37-degree helix angle. The right-hand cut, right-hand flute geometry promotes efficient chip evacuation. The bright uncoated finish is standard for this micrograin carbide grade, designated K600. Centercutting capability allows direct plunge entry into workpiece material. Licensed machinists and CNC programmers typically specify this tool for ferrous and non-ferrous finishing passes where tight tolerances are required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills handling light-to-medium milling work. The 0.25-inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit tooling. The 2-inch overall length keeps the tool compact for rigidity in shallow-pocket and contour milling applications. Its single-end design means the tool is replaced rather than reversed when the cutting edge is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, material grade K600 micrograin for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design with 37-degree helix angle for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunging without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous materials and applications where coating buildup is a concern\u003c\/li\u003e\n\u003cli\u003eShank diameter tolerance of +0.00000\/-0.00035 inches and mill diameter tolerance of +0.000\/-0.002 inches for consistent fit in precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for AADE-series 0.25-inch square end mill applications using standard 0.25-inch shank toolholders including ER collet chucks and end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Verify collet or chuck runout is within acceptable tolerance before beginning a cut, as excessive runout will accelerate edge wear and degrade surface finish. Follow the toolholder manufacturer torque specifications when tightening set screws or collet nuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 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\u003eLength of Cut\u003c\/strong\u003e: 0.375 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000\/-0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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 Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K600 Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADE\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\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: 3658815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730375246130,"sku":"3658815","price":90.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8715698b9a80a37fa0e905bd455970c.jpg?v=1788716323","url":"https:\/\/voomisupply.com\/products\/kennametal-3658815-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
