Gws 310205 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The GWS 310205 is a solid carbide corner radius end mill engineered for high-performance material removal and finishing in demanding machining environments. The tool measures 3/8 inch in diameter with a 1/2 inch length of cut, a 0.01 inch corner radius, and a 2 inch overall length. The 3/8 inch straight-cylindrical shank meets h6 tolerance for precise toolholder fitment. Built from submicron-grade solid carbide, the 310205 delivers the rigidity and edge retention required for cutting steel, stainless steel, superalloys, and titanium. It is installed and operated by CNC machinists and tool-and-die professionals in production shop environments.

This end mill is suited for both roughing and finishing operations in vertical and horizontal machining centers. Its 4-flute, variable-helix, variable-index geometry reduces chatter and harmonic vibration during aggressive cuts. The centercutting design allows plunge entry, expanding operational flexibility. Primary target workpiece materials are steel, stainless steel, superalloys, and titanium, with secondary application in cast iron. The short length type and rigid carbide substrate make it well suited for tight-tolerance work where deflection control is critical.

Key Features

• Solid submicron-grade carbide construction for superior hardness and edge retention
• 0.01 inch corner radius reduces stress concentration and extends workpiece edge life
• Variable helix and variable index geometry dampens vibration during cuts
• Centercutting design enables direct plunge milling without a pre-drilled entry hole
• Right-hand flute direction and right-hand cutting for standard spindle operation
• Shank diameter tolerance h6 ensures consistent seating in standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders accepting a 3/8 inch straight-cylindrical shank. Suitable for machining steel, stainless steel, superalloys, titanium, and cast iron on CNC vertical or horizontal machining centers.

Installation Notes

Install and remove end mills only with the spindle fully stopped and machine power isolated per shop lockout/tagout procedures. Seat the shank fully into the toolholder and torque the retention fastener to the toolholder manufacturer specification before operating. Inspect the cutting edges and corner radius for chips or wear before each use. Coolant-through is not supported on this tool, so ensure adequate external coolant or air-blast delivery is directed at the cutting zone.
