Gws 120968 Square End Mill 5/8 in 5 Flute Solid Carbide

Product Description

The GWS 120968 is a solid carbide square end mill designed for high-performance material removal in professional machining environments. With a 5/8 inch cutting diameter, 5 flutes, and a 2-1/4 inch length of cut, this tool delivers aggressive chip evacuation and a superior surface finish in a single operation. The variable 38-degree helix angle reduces chatter and cutting forces, making it well-suited for finishing and semi-finishing passes on ferrous and non-ferrous materials. The nACRo coating provides enhanced heat resistance and wear protection for extended tool life in demanding cutting conditions. This end mill is installed and operated by machinists in job shop, manufacturing, and tool-and-die environments.

The 120968 is applicable to CNC milling centers and manual mills handling materials that benefit from a high-flute-count finishing tool with variable helix geometry. The 5-inch overall length and 5/8 inch shank diameter allow mounting in standard collet chucks and end mill holders. Right-hand cutting and right-hand flute direction are consistent with conventional CNC spindle rotation. The Series 1035 designation identifies this as part of a specific GWS tooling family intended for precision milling applications where surface quality and dimensional accuracy are priorities.

Key Features

• 5/8 inch cutting diameter with a matching 5/8 inch shank for rigid, concentric seating in standard holders
• 5-flute geometry increases feed rates and improves finish quality compared to standard 4-flute designs
• Variable helix angle reduces harmonic vibration and chatter during full-length cuts
• nACRo coating provides elevated heat resistance and extended wear life on hard and abrasive materials
• Submicron-grade solid carbide substrate delivers consistent edge retention and dimensional stability
• Single-end, right-hand upcut design for direct compatibility with standard CNC spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with standard 5/8 inch collet chucks, end mill holders, and shrink-fit tooling systems used in CNC vertical and horizontal milling centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and locked before mounting or removing the end mill. Seat the shank to the minimum recommended insertion depth as specified by the holder manufacturer to maximize rigidity and prevent tool pullout. Verify runout at the tool tip with a dial indicator before initiating a cut.
