Gws 315173 Square End Mill 1/2 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 315173 is a single-end square end mill designed for precision milling operations in metal and alloy workpieces. Built from submicron-grade solid carbide, it delivers the hardness and wear resistance required for demanding cuts. The tool carries a ZrN (zirconium nitride) coating that reduces friction and extends tool life in high-speed applications. With a 0.5-inch mill diameter, a 1.25-inch length of cut, and a 37-degree helix angle, it is engineered for right-hand cutting with an upcut flute geometry. Machinists and tool-and-die professionals working on CNC mills and manual milling machines will find this a direct-fit workhorse end mill.

This end mill is suited for ferrous and non-ferrous machining applications in job shop, production, and maintenance environments. The 3-flute configuration balances chip evacuation with surface finish quality, making it a practical choice for slotting, profiling, and peripheral milling. The centercutting capability allows plunge entry without a pre-drilled pilot. It is a single-end tool, so it is replaced when worn rather than flipped. Typical applications include steel, aluminum, and hard plastics on CNC machining centers and knee mills.

Key Features

• Submicron-grade solid carbide construction for hardness and thermal stability
• ZrN coating reduces friction and improves wear resistance in high-speed cuts
• 37-degree right-hand helix with upcut flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry
• 3-flute configuration balances material removal rate with surface finish quality
• Series 2031 single-end configuration with 0.5-inch shank for standard collet or end mill holder fitment

Compatibility

Designed for use in standard 0.5-inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills. Verify spindle taper and holder bore before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before seating or removing the tool. Use a properly sized collet or end mill holder torqued to the toolholder manufacturer's specification to prevent pullout under load. Inspect the tool shank and cutting edges for damage before each use, and replace the tool at the first sign of chipping or excessive wear.
