Gws 311480 Corner Radius End Mill 5/16 in 5 Flute Carbide

Product Description

The GWS 311480 is a solid carbide corner radius end mill designed for high-performance material removal in steel, stainless steel, superalloys, and titanium. It features a 5/16 inch cutting diameter, five flutes, and a 0.01 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The variable helix and variable index geometry minimize chatter and improve surface finish across both roughing and finishing passes. This tool is intended for use by machinists and CNC operators working in production or job-shop environments.

The GWS 311480 is suited for milling applications involving steel, stainless steel, superalloys, titanium, and cast iron. Its short flute length and centercutting capability make it effective for slotting, profiling, and plunge operations on CNC machining centers. The straight cylindrical shank with h6 tolerance ensures consistent runout when seated in standard end mill toolholders. It is classified under Series 2205 and carries a submicron carbide grade substrate optimized for high-hardness workpiece materials.

Key Features

• Solid carbide submicron grade substrate for rigidity and wear resistance in hard materials
• Variable helix and variable index design reduces harmonic vibration during cutting
• 0.01 inch corner radius reduces edge chipping and improves corner strength
• Centercutting geometry allows direct plunge entry into workpiece material
• Five-flute configuration supports higher feed rates compared to standard four-flute tools
• Right-hand cut, right-hand spiral flute direction for use with conventional CNC spindle rotation

Compatibility

Designed for use with standard end mill toolholders accepting a 5/16 inch straight cylindrical shank with h6 tolerance. Primary workpiece materials are steel, stainless steel, superalloys, and titanium; secondary application includes cast iron.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and power is locked out before loading or unloading the tool. Seat the shank fully into the toolholder and torque the retention mechanism according to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a production run, particularly when machining superalloys or titanium where tool deflection is critical.
