Gws 311432 Square End Mill 1/4 in 5 Flute Solid Carbide

Product Description

The GWS 311432 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from submicron-grade carbide and coated with AlCrO-MAX, it is engineered to handle tough ferrous and non-ferrous materials at elevated speeds and feeds. The 1/4 inch diameter cutter features a 3/4 inch length of cut and a 38-degree helix angle, which helps evacuate chips efficiently and reduce chatter. At 2.5 inches overall length with a 1/4 inch shank, this is a compact, rigid tool suited for CNC machining centers and manual knee mills alike. Machinists and toolroom operators are the primary users.

This end mill is well-suited for finish milling, slotting, and profiling operations in ferrous alloys, stainless steels, and hardened materials where standard coatings fall short. The single-end, right-hand cut and right-hand flute configuration make it a drop-in fit for standard spindle toolholders. The Series 2205 designation places it within a product line built for general to high-performance milling at standard lengths. It is appropriate for both production shop floors and job shop environments where tool life and surface finish consistency are critical priorities.

Key Features

• AlCrO-MAX coating provides oxidation resistance and extended tool life in high-heat applications
• 5-flute design increases feed rate capability compared to 4-flute equivalents at the same diameter
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Submicron solid carbide substrate delivers rigidity and edge retention
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute orientation compatible with standard CNC spindle toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/4 inch collet chucks, end mill holders, and hydraulic toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the holder and torque the retention hardware to the toolholder specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear and degrades surface finish.
