Gws 312025 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The GWS 312025 is a 5-flute, single-end, solid carbide square end mill designed for precision milling in demanding machining environments. Built from submicron-grade carbide and finished with an AlCrO-MAX coating, this tool handles high-temperature cutting applications where tool life and edge retention are critical. The mill features a 1/8 inch diameter, a 0.1562 inch length of cut, and a 2 inch overall length. A 38-degree right-hand helix and right-hand cutting direction promote efficient chip evacuation and reduce heat buildup at the cutting edge. Centercutting capability allows for plunge entry, broadening its application range. Installed by machinists and tooling professionals in CNC and manual milling setups.

This end mill is suited for finish milling, slotting, and profiling operations on hardened steels, stainless alloys, and high-temperature materials where conventional coatings fall short. The extended reach geometry makes it practical for milling deeper features without tool interference. Series 2213 construction targets high-precision work in job shop, aerospace, and die-mold machining environments. The 1/8 inch shank diameter is compatible with standard collet systems and end mill holders commonly found in vertical machining centers and CNC routers.

Key Features

• 5-flute design increases feed rates and improves surface finish compared to standard 4-flute tools
• AlCrO-MAX coating provides oxidation resistance and extended tool life in high-heat cutting conditions
• Submicron-grade solid carbide substrate delivers edge sharpness and wear resistance
• 38-degree right-hand helix promotes smooth chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge milling without a pre-drilled entry point
• Extended reach configuration accommodates deeper feature milling with reduced tool deflection risk

Compatibility

Designed for use with standard 1/8 inch collets and end mill holders in CNC vertical machining centers, CNC routers, and manual knee mills equipped to accept square-shank tooling.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before production cutting, as excessive runout accelerates wear on small-diameter carbide tools.
