Gws 312575 Square End Mill 3/8 in 7 Flute Solid Carbide

Product Description

The GWS 312575 is a 7-flute, solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. It features a 3/8 inch cutting diameter, a 1/2 inch length of cut, and a 2 inch overall length. The AlCrO-MAX coating provides enhanced heat and oxidation resistance, making it well suited for dry or near-dry machining at elevated surface speeds. The 38-degree helix angle promotes efficient chip evacuation while reducing cutting forces. This tool is built on a submicron carbide substrate, delivering the edge retention and rigidity needed in production environments.

The GWS 312575 is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling operations. Its 7-flute geometry makes it particularly effective in finishing and semi-finishing passes where higher feed rates and improved surface finish are priorities. The right-hand cutting and right-hand flute direction suit standard spindle configurations. It is a single-end tool with a square shank and is commonly installed in collet chucks or end mill holders by machinists and CNC operators working in job shops, toolrooms, and production facilities.

Key Features

• 7-flute design supports higher feed rates and improved surface finish in finishing passes
• AlCrO-MAX coating provides oxidation and heat resistance for elevated-speed cutting
• 38-degree helix angle promotes efficient chip evacuation and reduces radial cutting forces
• Submicron solid carbide substrate delivers superior edge retention and rigidity
• Center-cutting capable for plunge entry operations
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed as a standard 3/8 inch shank square end mill compatible with collet chucks, shrink-fit holders, and end mill holders accepting 3/8 inch round shanks in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The tool shank must be fully seated to the recommended engagement depth in the holder before tightening to prevent pullout under cutting loads. Inspect the collet or holder for wear or runout before mounting. Ensure the machine spindle is fully stopped and the control is in a safe state before tool changes.
