Gws 119338 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The GWS 119338 is a solid carbide corner radius end mill designed for high-performance milling in demanding production environments. Built with a 0.5 inch diameter, a 0.015 inch corner radius, and 4 flutes, this single-end tool handles both roughing and finishing operations in one setup. The submicron carbide grade and right-hand spiral flute geometry deliver clean material removal with consistent edge retention. At 3 inches overall length with a 0.5 inch straight-cylindrical shank and a 0.345 inch length of cut, this end mill fits standard end mill toolholders and suits applications where tight tolerances and surface quality matter. Centercutting capability allows plunge entry without a pre-drilled hole.

This end mill is intended for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is suited to CNC milling operations in job shops and production facilities where a single tool must transition between roughing passes and finish cuts. The short length type and variable index and variable helix geometry reduce chatter and harmonics during aggressive cuts, making it a practical choice for machinists working in difficult-to-machine alloy families. Right-hand cutting direction is standard for conventional CNC machining center setups.

Key Features

• 0.015 inch corner radius reduces stress concentration at the cutting edge and extends tool life in hard materials
• Variable index and variable helix design suppresses chatter during roughing and finishing passes
• Centercutting geometry enables direct plunge entry without a pilot hole
• Submicron solid carbide substrate delivers hardness and wear resistance in ferrous and superalloy cuts
• Right-hand spiral flute with normal pitch optimizes chip evacuation in steel and cast iron
• Straight-cylindrical shank with h6 tolerance fits standard end mill toolholders with minimal runout

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials include steel, cast iron, superalloys, titanium, and hard materials. Secondary workpiece material is stainless steel. UNSPSC code 27112803.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down the spindle and confirm zero-speed before inserting or removing the tool from the holder. Verify holder bore cleanliness and shank seating before torquing the collet or set screw to the toolholder manufacturer specification. Confirm correct cutting direction and spindle rotation match the right-hand flute orientation before starting a program.
