Gws 310921 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The GWS 310921 is a solid carbide square end mill designed for high-performance metal removal in demanding machining applications. Built from submicron-grade carbide and coated with AlCrO-MAX, it delivers extended tool life in abrasive and high-temperature cutting environments. The 4-flute, right-hand cutting geometry with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes. With a 0.5 inch mill diameter, 5/8 inch length of cut, and 6 inch overall length, this end mill suits a range of slotting, peripheral milling, and profiling operations. It is a single-end, center-cutting tool with an upcut flute configuration, ready for use in CNC machining centers and manual mills.

This end mill is intended for use in professional machine shop environments where consistent tolerances and tool reliability are required. The extended reach design makes it suitable for deeper-pocket applications where standard-length tooling cannot reach. It fits 1/2 inch toolholders including collet chucks, shrink-fit holders, and end mill holders commonly found in production and job shop settings. Machinists working with hardened steels, stainless alloys, and high-temperature alloys will find the AlCrO-MAX coating particularly effective at reducing heat buildup and edge wear.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance
• AlCrO-MAX coating reduces thermal wear in high-speed and dry cutting
• 38-degree right-hand helix with upcut flutes for efficient chip evacuation
• Center-cutting design allows direct plunge entry into workpieces
• Extended reach geometry for deep-pocket and hard-to-reach features
• Single-end configuration with square shank for standard toolholder compatibility

Compatibility

Designed for use with 1/2 inch bore toolholders in CNC machining centers and manual milling machines. Part of the GWS Series 2105 end mill line.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly torqued toolholder and verify runout with a dial indicator before cutting. Follow the toolholder manufacturer specifications for clamping force and engagement length to prevent tool pullout.
