Seco 10023134 Corner Radius End Mill 1/4 in 3 Flute Carbide

Product Description

The SECO 10023134 is a solid carbide corner radius end mill designed for precision milling in non-ferrous metal applications. It features a 1/4-inch cutting diameter with a 0.0600-inch corner radius, a 3-flute geometry, and a 45-degree high helix for efficient chip evacuation. The tool is finished with an ANF PVD coating to extend tool life and reduce built-up edge in aluminum and other non-ferrous materials. At 4 inches overall length with a 3/4-inch length of cut and 1-1/2-inch reach, this is a long-reach configuration suited to deeper cavity work. Centercutting geometry allows plunge entry. It belongs to SECO's AN345R series, which targets both roughing and finishing operations in a single tool.

This end mill is appropriate for CNC machining centers and manual mills running non-ferrous workpiece materials including aluminum, copper, brass, and similar alloys. The extended reach and long overall length make it well-suited for mold work, aerospace components, and deep-pocket profiling where standard-length tools cannot reach. The 1/4-inch straight cylindrical shank fits standard collet toolholders. The coarse pitch and high helix angle support aggressive material removal while maintaining surface finish quality in finishing passes.

Key Features

• 0.0600-inch corner radius reduces stress concentration and extends tool and workpiece life
• ANF PVD coating optimized for non-ferrous metal cutting, reduces adhesion and built-up edge
• 3-flute, right-hand spiral geometry with high 45-degree helix for fast chip evacuation
• Extended reach design with 1-1/2-inch reach length for deep-pocket and cavity milling
• Centercutting — capable of direct plunge entry without a pre-drilled hole
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds
• Single-end, straight cylindrical shank for use with standard collet-style toolholders

Compatibility

Designed for use with standard collet-style toolholders accepting a 1/4-inch straight cylindrical shank. Part of the SECO AN345R series, configured for non-ferrous metal machining in roughing and finishing applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the toolholder collet bore is clean and free of chips before seating the shank to maintain runout within the specified TIR maximum of 0.0005 inches. Verify proper stick-out and reach clearance before running a program, particularly in deep-pocket applications where the neck diameter of 0.2400 inches provides relief but limits lateral load capacity. Follow the machine tool manufacturer's guidelines for speeds, feeds, and clamping torque for the toolholder in use.
