Gws 310346 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The GWS 310346 is a solid carbide corner radius end mill built for high-performance metal removal and finishing in demanding machining environments. It features a 1/2 inch diameter cutting edge with a 0.06 inch corner radius, a 2 inch length of cut, and a 4 inch overall length. The 4-flute, single-end configuration with a variable helix and variable index design reduces harmonic vibration during heavy cuts, making it effective for both roughing and finishing operations. The submicron carbide grade provides the edge strength and wear resistance required when cutting difficult alloys.

This end mill is suited for milling operations on steel, stainless steel, superalloys, titanium, and cast iron in CNC machining centers and manual mills. The centercutting geometry allows plunge entry, and the right-hand flute direction with right-hand cutting rotation matches standard spindle setups. It fits standard end mill holders with a 1/2 inch straight-cylindrical shank held to h6 tolerance. Typical applications include profiling, slotting, and contour milling where corner integrity and surface finish both matter.

Key Features

• Solid carbide submicron grade construction for strength in hard and abrasive materials
• 0.06 inch corner radius reduces stress concentration and extends tool life at part corners
• Variable helix and variable index design dampens vibration during aggressive cuts
• Centercutting capability allows direct plunge entry without pre-drilling
• 4 flutes with helical flute geometry for efficient chip evacuation
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use with standard end mill holders accepting a 1/2 inch straight-cylindrical shank. Primary workpiece materials are steel, stainless steel, superalloys, and titanium. Secondary workpiece material is cast iron.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling and end mill holder systems. Ensure the spindle is fully stopped and locked before inserting or removing the tool. Seat the shank fully into the holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, particularly when working with superalloys or titanium where tool deflection tolerance is low.
