Gws 311759 Corner Radius End Mill 5/8 in 5 Flute Carbide

Product Description

The GWS 311759 is a solid carbide corner radius end mill engineered for high-performance material removal in ferrous machining applications. It features a 5/8-inch cutting diameter, a 2-1/2-inch length of cut, and a 0.06-inch corner radius that reduces stress concentration at the cutting edge and extends tool life. With 5 flutes and a variable helix design, the 311759 delivers smooth chip evacuation and reduced harmonic vibration during both roughing and finishing passes. It is center-cutting and right-hand cutting with a straight cylindrical shank sized to fit standard end mill holders.

This end mill is designed for use in CNC machining centers and manual mills where tight tolerances and surface finish quality are required across a range of ferrous materials. At 5 inches overall length, it provides extended reach for deeper pocket or contour work without sacrificing rigidity. It is well suited for job shops, toolrooms, and production environments running steel, stainless steel, superalloys, titanium, and cast iron. The FX3 AlCr coating enhances hardness and heat resistance, making it particularly effective in dry or semi-dry cutting conditions.

Key Features

• Solid carbide submicron-grade construction for wear resistance in demanding alloys
• Variable helix and variable index geometry reduces chatter and improves surface finish
• 0.06-inch corner radius reduces edge chipping and stress on the workpiece corner
• 5 flutes with right-hand helical flute direction for efficient chip evacuation
• FX3 AlCr coating rated for steel, stainless steel, superalloys, titanium, and cast iron
• Center-cutting design allows plunge entry directly into the workpiece

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, stainless steel, superalloys, and titanium (ISO material codes P, M, S). Secondary workpiece material is cast iron (ISO code K). Part of the GWS Series 2205 long-length end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the shank. The h6 shank diameter tolerance is specified for precision collet and end mill holder fitment - verify holder bore specification before clamping. Confirm correct runout with a dial indicator before beginning a production cut.
