Gws 311640 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The GWS 311640 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. It features a 1/2 inch diameter cutting head with a 0.03 inch corner radius, 5 flutes, and a 1-1/4 inch length of cut. The variable helix and variable index geometry reduce harmonic chatter during aggressive cuts, making this tool effective for both roughing and finishing operations. It carries an AlCr-based FX3 coating suited for hard material applications. Machinists and tooling professionals working in production shops or job shops will find this end mill appropriate for CNC milling centers using standard end mill holders.

This end mill is intended for use on steel, stainless steel, superalloys, titanium, and cast iron workpieces. The centercutting design allows plunge entry, adding flexibility for slotting and pocket milling operations. The straight cylindrical shank with h6 tolerance provides consistent, repeatable tool holding in standard end mill holders. It is suited to both light finishing passes and heavier material removal cycles where tool life and edge stability matter.

Key Features

• 1/2 inch cutting diameter with 0.03 inch corner radius for edge strength and reduced chipping
• 5 flutes with variable helix and variable index for chatter reduction
• FX3 AlCr coating rated for steel, stainless steel, superalloys, titanium, and cast iron
• Centercutting design supports plunge milling and full slot operations
• Solid carbide submicron grade substrate for hardness and wear resistance
• Right-hand cut and right-hand flute direction; single end configuration

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, stainless steel, superalloys, and titanium; secondary workpiece material is cast iron. Series 2205.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and locked out per facility safety procedures. Ensure the shank is fully seated and properly torqued in the end mill holder before operation. Verify spindle speed and feed rate settings are appropriate for the workpiece material and depth of cut before engaging the tool. Do not exceed the tool manufacturer's recommended operating parameters for this diameter and coating.
