Gws 314930 Corner Radius End Mill 5/8 in 3 Flute Carbide

Product Description

The GWS 314930 is a solid carbide corner radius end mill designed for precision milling of non-ferrous metals. It features a 5/8 inch cutting diameter, a 0.0900 inch corner radius, and three right-hand spiral flutes with a 37-degree high helix angle. The NF1 coating is applied to improve performance on aluminum and other non-ferrous workpiece materials. At 3.5 inches overall length with a 1.625 inch length of cut, this is a single-end, centercutting tool suited for slotting, profiling, and roughing operations. It is installed by machinists and CNC operators using standard end mill toolholders.

The GWS 314930 is intended for use on non-ferrous metals such as aluminum, brass, and copper in milling applications. The coarse pitch and high helix geometry promote efficient chip evacuation in these materials. The centercutting capability allows plunge entry when the operation requires it. This tool fits standard straight-cylindrical end mill toolholders with h6 shank tolerance and is used in vertical machining centers, CNC mills, and manual knee mills running appropriate feeds and speeds for the workpiece material.

Key Features

• Solid submicron carbide construction for rigidity and edge retention in non-ferrous applications
• 0.0900 inch corner radius reduces stress concentration at the cutting edge and improves surface finish at part corners
• NF1 coating optimized for non-ferrous metal cutting
• 37-degree high helix angle promotes aggressive chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute spiral; coarse pitch for roughing material removal
• Series 2030 single-end configuration with straight-cylindrical shank at h6 tolerance

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece material is non-ferrous metal. Shank diameter is 5/8 inch with h6 tolerance for accurate fitment in collet chucks, set-screw holders, and hydraulic toolholders accepting that shank size.

Installation Notes

Installation is performed by a machinist or CNC operator. The machine spindle must be fully stopped and the toolholder secured in the spindle before inserting or removing the end mill. Confirm shank engagement depth meets toolholder manufacturer minimums before tightening. Verify runout with a dial indicator after tool installation to ensure concentricity within acceptable limits for the operation.
