Gws 310819 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The GWS 310819 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. It features a 3/8 inch cutting diameter with a 0.02 inch corner radius that reduces edge chipping and extends tool life on hardened and difficult-to-machine materials. The 4-flute, single-end configuration supports both roughing and finishing passes in a single setup. With a 1/2 inch length of cut, a 4 inch overall length, and a straight cylindrical shank with h6 tolerance, this tool is built for rigid setups in standard end mill toolholders. The submicron carbide grade provides the hardness and wear resistance needed when cutting steel, stainless steel, superalloys, and titanium.

This end mill is suited for CNC machining centers and manual mills handling steel, stainless steel, superalloys, titanium, and cast iron. The centercutting geometry allows plunge entry, and the variable helix and variable index design reduce harmonic chatter during aggressive cuts. The extended reach configuration, with a 1.125 inch reach length, gives clearance for deeper pockets and stepped features without requiring a long-reach toolholder. It is intended for professional machinists and toolroom applications where tight tolerances and surface finish matter.

Key Features

• 0.02 inch corner radius reduces stress concentration and chipping at the cutting edge
• Submicron solid carbide grade for cutting steel, stainless steel, superalloys, titanium, and cast iron
• Variable helix and variable index flute geometry reduces chatter during high-load cuts
• Centercutting design allows direct plunge entry into workpiece material
• Extended reach with 1.125 inch reach length for deeper pocket and stepped-feature access
• Straight cylindrical shank with h6 tolerance for precise fit in standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials are steel, stainless steel, superalloys, and titanium. Secondary workpiece material is cast iron.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a fully stopped and locked-out state. Ensure the toolholder bore and shank are clean and free of chips before seating the tool. Torque the retention knob or collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
