Gws 101002 Square End Mill 3/8in 3 Flute Solid Carbide Zrn

Product Description

The GWS 101002 is a solid carbide square end mill engineered for high-performance aluminum and non-ferrous metal milling. It features a 3/8 inch cutting diameter, a 1-1/2 inch length of cut, and three right-hand flutes with a 37-degree helix angle. The ZrN (zirconium nitride) coating reduces built-up edge and heat transfer, extending tool life in aluminum applications. Manufactured from submicron carbide grade material, it delivers the rigidity and edge retention needed for demanding production environments. This is a single-end, center-cutting tool with right-hand cutting direction and an upcut flute geometry.

The 101002 belongs to the GWS Series 1025 Alumigator line, which is purpose-built for milling aluminum alloys, soft metals, and similar non-ferrous materials. It is suited for CNC machining centers and manual mills in job shop, aerospace, and general manufacturing environments. The 3/8 inch shank diameter matches common ER collet and end mill holder sizes, and the 4 inch overall length provides adequate reach for most standard fixturing setups. Machinists and CNC operators working in production shops will find this tool appropriate for slotting, profiling, and pocketing operations in aluminum.

Key Features

• 3 right-hand upcut flutes with 37-degree helix angle optimized for aluminum chip evacuation
• ZrN coating reduces built-up edge and extends tool life in non-ferrous applications
• Submicron solid carbide construction for rigidity and edge retention
• Center-cutting design allows plunge entry as well as peripheral cutting
• Part of the GWS Series 1025 Alumigator line for aluminum-focused applications

Compatibility

Designed for use in the GWS Series 1025 Alumigator line; compatible with standard 3/8 inch ER collets and end mill holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the 3/8 inch shank firmly in a properly sized collet or end mill holder, torqued to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when precision is required.
