Seco 10023040 Corner Radius End Mill 5/32 in 3 Flute Carbide

Product Description

The SECO 10023040 is a single-end corner radius end mill designed for precision milling of non-ferrous metals. Built from solid carbide, it features a 5/32-inch (0.1562-inch) mill diameter, a 0.0200-inch corner radius, and three right-hand spiral flutes with a high-angle helix. The tool carries an ANF PVD coating that extends cutting life on aluminum, copper, brass, and similar materials. At 2 inches overall length with a 1/2-inch length of cut, this end mill suits both roughing and finishing passes in a standard toolholder setup. It is center-cutting, allowing direct plunge entry without a pre-drilled pilot hole.

The 10023040 is intended for CNC machining centers and manual mills where tight tolerances and clean surface finishes on non-ferrous workpieces are required. Its 3/16-inch straight-cylindrical shank fits standard toolholders commonly used in production and job-shop environments. The coarse pitch combined with the high-helix geometry promotes efficient chip evacuation, reducing heat buildup during high-speed passes on aluminum and other gummy materials. This tool is appropriate for machinists, toolroom technicians, and CNC operators working within aerospace, automotive, and general manufacturing applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous milling
• ANF PVD coating extends tool life and reduces friction on aluminum and non-ferrous alloys
• 0.0200-inch corner radius reduces stress concentration at cutting edges
• Center-cutting design allows direct plunge milling without a pilot hole
• Three right-hand flutes with high-helix geometry for efficient chip evacuation
• Handles both roughing and finishing passes in a single tool

Compatibility

Designed for use with standard straight-cylindrical toolholders. Optimized for non-ferrous metal workpiece materials including aluminum, brass, and copper. Part of the SECO Series A345R end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle at a full stop before tool changes. Seat the straight shank fully into the toolholder collet and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout does not exceed the 0.0005-inch TIR maximum before beginning production cuts. Confirm workpiece material compatibility before applying cutting parameters, as this tool is engineered specifically for non-ferrous applications.
