Gws 125654 Corner Radius End Mill 5/16 in 3 Flutes

Product Description

The GWS 125654 is a solid carbide corner radius end mill designed for precision milling in non-ferrous metal applications. It features a 5/16-inch (0.3125-inch) mill diameter with a 0.05-inch corner radius, which reduces edge chipping and extends tool life compared to sharp-corner geometry. The 3-flute, right-hand spiral configuration with a high helix angle promotes efficient chip evacuation and smooth cutting action. At 3 inches overall length with a 1-1/8-inch length of cut, this single-end, centercutting tool handles both plunge and peripheral milling. It is installed by machinists and CNC operators working in job shops, aerospace, and general manufacturing environments.

This end mill is suited for roughing operations in non-ferrous metals such as aluminum, brass, copper, and similar materials. The coarse pitch and high helix style make it effective for high-material-removal-rate applications where chip load and evacuation are priorities. The bright/uncoated finish is well-matched to non-ferrous workpiece materials where coating adhesion is less of a concern. The 5/16-inch straight cylindrical shank with h6 tolerance fits standard end mill toolholders used on vertical machining centers and manual knee mills.

Key Features

• 0.05-inch corner radius reduces stress concentration and extends tool life in roughing passes
• 3-flute solid carbide construction with submicron carbide grade for rigidity and wear resistance
• Centercutting geometry allows direct plunge entry without a pilot hole
• High helix, right-hand spiral flute promotes chip evacuation in non-ferrous materials
• Bright/uncoated finish optimized for aluminum and other non-ferrous metals
• 5/16-inch straight cylindrical shank (h6 tolerance) fits standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders accepting a 5/16-inch straight cylindrical shank. Intended for non-ferrous metal workpiece materials per the manufacturer primary material designation.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a safe, locked-out state. Secure the shank to the specified toolholder collet or set-screw holder before starting the spindle. Verify runout with a dial indicator after clamping, as excessive runout shortens tool life and degrades surface finish. Do not exceed the toolholder manufacturer recommended clamping torque for this shank diameter.
