Gws 312374 Square End Mill 3/4 in 5 Flute Solid Carbide

Product Description

The GWS 312374 is a 5-flute, solid carbide square end mill designed for high-performance milling operations in demanding shop environments. Built from submicron-grade carbide and finished with an AlCrO-MAX coating, it delivers strong heat and wear resistance in ferrous and non-ferrous materials. The 3/4-inch diameter cutter features a 1-inch length of cut, a 38-degree helix angle, and right-hand cutting and flute direction. It measures 6 inches overall and accepts a 3/4-inch square shank. This tool is installed and operated by machinists and tool-and-die professionals working on CNC and manual milling equipment.

The 312374 is suited for slotting, profiling, and peripheral milling in production and job-shop settings. The extended-reach geometry and upcut flute configuration make it effective for deeper cavity work and efficient chip evacuation. The 5-flute count supports higher feed rates compared to standard 4-flute designs, making it a practical choice for finishing and semi-finishing passes in steel, stainless, and similar hard materials. This is a single-end tool from GWS Series 2213.

Key Features

• Submicron solid carbide construction for rigidity and edge retention
• AlCrO-MAX coating provides high-temperature and wear resistance
• 5 flutes with right-hand upcut geometry for efficient chip evacuation
• 38-degree helix angle reduces cutting forces and improves surface finish
• Center-cutting capable - allows plunge entry
• Extended-reach design supports deeper cavity and profiling work

Compatibility

Designed as a standard-shank replacement end mill for CNC machining centers and manual mills accepting a 3/4-inch square shank collet or end mill holder. Part of GWS Series 2213.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the set screw or collet nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm feed and speed parameters match the workpiece material and coating requirements.
