Gws 125982 Corner Radius End Mill 3/4 in 3 Flute Carbide

Product Description

The GWS 125982 is a solid carbide corner radius end mill engineered for material removal in non-ferrous metal applications. It features a 3/4-inch mill diameter, a 2-1/2-inch length of cut, and a 0.06-inch corner radius that reduces stress concentration at the cutting edge and extends tool life in roughing operations. The three-flute, right-hand spiral design promotes efficient chip evacuation while maintaining rigidity in the cut. At 5 inches overall length and with a straight cylindrical shank, this tool mounts directly into standard end mill toolholders. It is used by machinists and tool-and-die professionals running CNC mills and manual knee mills.

This end mill is suited for roughing passes on non-ferrous metals including aluminum, brass, and copper alloys. The coarse pitch flute geometry and high helix style support aggressive stock removal while the uncoated bright finish is appropriate for materials where coating adhesion can cause built-up edge. The long-length configuration provides extended reach into deeper cavities or stepped features without requiring a specialty extended-reach holder. The submicron carbide grade offers consistent edge integrity across high-cycle production runs.

Key Features

• Solid carbide submicron grade construction for consistent edge retention in roughing operations
• 0.06-inch corner radius reduces edge chipping and stress at the tool tip
• Three-flute right-hand spiral with coarse pitch promotes efficient chip evacuation
• High helix style supports aggressive material removal on non-ferrous metals
• Straight cylindrical shank with h6 tolerance fits standard end mill toolholders
• Uncoated bright finish suited for non-ferrous metals where coating buildup is a concern

Compatibility

Designed for use with standard end mill toolholders. Intended for machining non-ferrous metals. Shank diameter tolerance is h6, compatible with collet chucks and hydraulic holders sized for 3/4-inch shanks.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Confirm correct tool offset and runout with a dial indicator before engaging the cut. Always observe machine guarding requirements and appropriate feeds and speeds for the workpiece material.
