Gws 121652 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The GWS 121652 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal applications. It features a 3/8-inch diameter, a 1-inch length of cut, and a 0.03-inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to a sharp-corner geometry. With 3 right-hand helical flutes and a high helix style, this end mill promotes efficient chip evacuation at aggressive material removal rates. It is a single-end, centercutting tool, meaning it can plunge directly into the workpiece. The submicron carbide grade provides the hardness and wear resistance needed for consistent performance in non-ferrous metals.

This end mill is suited for machining non-ferrous metals including aluminum, copper, and brass alloys. The coarse pitch and roughing material removal type make it appropriate for high-stock-removal passes rather than finishing cuts. Its straight-cylindrical shank with h6 tolerance is compatible with standard end mill holders. Machinists and tooling specialists working in CNC milling environments will find this tool appropriate for both production and job-shop applications requiring reliable corner geometry control.

Key Features

• Solid submicron carbide construction for hardness and wear resistance in non-ferrous metal cutting
• 0.03-inch corner radius reduces edge chipping and extends tool life versus sharp-corner end mills
• 3 right-hand helical flutes with high helix style promote efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Coarse pitch, roughing geometry optimized for high material removal rates
• Uncoated bright finish; no coating thickness to account for in tight-tolerance setups

Compatibility

Designed for use with standard end mill holders accepting a 3/8-inch straight-cylindrical shank with h6 tolerance. Primary workpiece material is non-ferrous metal.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify the shank is fully seated and the collet or set-screw holder is torqued per the holder manufacturer specifications before initiating a cut. Inspect the cutting edges for chipping before each use, as carbide tools can fracture if run with pre-existing edge damage.
