Gws 310621 Square End Mill 1-1/4 in 4 Flute Solid Carbide

Product Description

The GWS 310621 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built from submicron-grade carbide and coated with AlCrO-MAX for extended tool life, this single-end mill features a 1-1/4 inch cutting diameter with a 1-1/2 inch length of cut. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Four right-hand flutes with an upcut flute direction make it suitable for a wide range of metalcutting and finishing operations. Machinists and tool-and-die professionals are the primary installers and operators of this tooling.

This end mill is suited for use in CNC machining centers and manual knee mills where aggressive material removal or finish passes are required. The 1-1/4 inch square shank seats directly into standard ER or side-lock toolholders at that bore size. The standard length designation and 4-1/2 inch overall length make it a practical choice for general-purpose pocketing, slotting, and peripheral milling operations in ferrous and non-ferrous metals. The AlCrO-MAX coating provides oxidation resistance at elevated cutting temperatures, extending tool life between regrinds.

Key Features

• Submicron solid carbide substrate for high hardness and wear resistance
• AlCrO-MAX coating provides oxidation resistance and extended tool life at elevated temperatures
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Four right-hand, upcut flutes for general-purpose milling and finishing
• Centercutting design allows plunge entry into the workpiece
• 1-1/4 inch square shank compatible with standard toolholders at that bore diameter

Compatibility

Designed for use with standard toolholders accepting a 1-1/4 inch square shank, including ER collet chucks and side-lock holders commonly used in CNC machining centers and manual mills.

Installation Notes

This tooling should be installed and operated by qualified machinists familiar with speeds, feeds, and depth-of-cut parameters appropriate for the workpiece material. Ensure the machine spindle is fully stopped and the machine is in a safe state before installing or removing the end mill. Use a torque wrench and the appropriate tool when tightening collet nuts or set screws to avoid shank damage. Inspect the cutting edges and shank for chips or runout before each use.
