Gws 310787 Corner Radius End Mill 1/4 in 4 Flute Carbide

Product Description

The GWS 310787 is a solid carbide corner radius end mill engineered for demanding material removal in steel, stainless steel, superalloys, and titanium. It features a 1/4 inch mill diameter, a 0.02 inch corner radius, and 4 helical flutes in a right-hand cutting direction with a variable helix and variable index geometry. The short flute length of 3/8 inch (0.143 inch cut length) combined with a 1-1/8 inch reach length and 4 inch overall length makes it well suited for both roughing and finishing passes. Manufactured from submicron-grade carbide, this single-end centercutting tool is built for precision and rigidity in production machining environments.

This end mill is designed for use in CNC machining centers and milling applications where high-performance material removal in ferrous and exotic alloys is required. Typical applications include profiling, slotting, and contour milling in steel, stainless steel, superalloys, titanium, and cast iron workpieces. The 1/4 inch straight cylindrical shank with h6 tolerance mounts directly into standard end mill holders. The extended reach design allows access to deeper features without sacrificing rigidity.

Key Features

• Solid submicron carbide construction for hardness and wear resistance in demanding alloys
• Variable helix and variable index geometry reduces chatter and improves surface finish
• 0.02 inch corner radius protects the cutting edge and extends tool life in interrupted cuts
• Centercutting design allows direct plunge entry into workpiece material
• Extended reach of 1-1/8 inch provides access to deeper features and pockets
• Right-hand flute direction and right-hand cutting for use with standard CNC spindle rotation

Compatibility

Compatible with standard end mill holders accepting a 1/4 inch straight cylindrical shank with h6 shank diameter tolerance. Suitable for use in CNC machining centers performing roughing and finishing operations on steel, stainless steel, superalloys, titanium, and cast iron workpieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the end mill holder and torque the retention mechanism per the holder manufacturer specifications. Confirm runout with a dial indicator before committing to a production cut, particularly given the small diameter of this tool.
