Gws 120955 Square End Mill 3/16 in 5 Flute Solid Carbide

Product Description

The GWS 120955 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. It features a 3/16 inch cutting diameter with a 5/8 inch length of cut, five flutes, and a variable 38-degree helix angle that reduces chatter and improves chip evacuation. The nACRo coating provides enhanced wear resistance and thermal stability, extending tool life in high-speed cutting conditions. At 2 inches overall length with a 3/16 inch shank diameter, this tool is suited for CNC machining centers and manual mills where tight tolerances and surface finish quality are priorities.

This end mill is built for milling ferrous and non-ferrous metals, hardened steels, and other challenging materials where submicron carbide grade tooling is required. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. The upcut flute geometry pulls chips away from the workpiece, reducing re-cutting and heat buildup. It is a single-end tool intended for production and toolroom environments operated by machinists and CNC programmers.

Key Features

• 5 flutes with variable helix angle for reduced vibration and improved surface finish
• nACRo coating for extended wear resistance in high-temperature cutting environments
• Submicron solid carbide construction for rigidity and long tool life
• Upcut flute geometry promotes efficient chip evacuation
• Right-hand cut and right-hand flute direction for standard CNC mill compatibility
• Square shank, single-end design for direct collet or end mill holder mounting

Compatibility

Designed as a standard shank square end mill compatible with collet chucks, end mill holders, and tool holders accepting a 3/16 inch shank diameter on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before tightening to the holder manufacturer torque specification. Verify runout with a dial indicator before beginning a cut.
