It features a 0.250-inch mill diameter, a 0.750-inch length of cut, and a 2.500-inch overall length with a matching 0.250-inch straight cylindrical shank. The 45-degree high helix angle promotes efficient chip evacuation, which is critical when cutting soft, gummy materials like aluminum. The bright\/uncoated finish is standard for non-ferrous work where coatings can cause material adhesion. This is a single-end, center-cutting tool suited for both roughing and finishing passes. It belongs to SECO Series AB245 and ships as a single unit.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where tight tolerances and clean surface finishes are required on aluminum, brass, copper, and similar non-ferrous workpiece materials. The ball nose geometry makes it well suited for 3D contouring, profiling, and slotting operations. Standard length designation means it fits most collet and end mill holder setups without requiring extended-reach toolholding. Machinists and tool and die professionals working with non-ferrous components will find this tool appropriate for production and prototype work alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003e45-degree high helix angle promotes fast chip evacuation in aluminum and non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003eBall nose geometry supports 3D contouring, ramp entry, and radius profiling\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish is optimized for non-ferrous materials where coating adhesion is a concern\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute configuration for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement or new-install ball end mill for machining setups that require a 0.250-inch diameter tool in aluminum and non-ferrous applications.

Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting; maximum TIR for this tool is 0.0005 inches.\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: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1250 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AB245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17003633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559792410930,"sku":"17003633","price":71.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fd9c40c42f107c6de51baaad473be80_fd140ca4-0364-4f46-ad39-4d33f8461b69.jpg?v=1786441210","url":"https:\/\/voomisupply.com\/products\/seco-17003633-ball-end-mill-1-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
