Gws 101011 Square End Mill 0.5 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 101011 is a 3-flute, solid carbide square end mill designed for high-performance milling applications, particularly in aluminum and non-ferrous materials. It features a 0.5 inch mill diameter, a 2.25 inch length of cut, and a 4 inch overall length with a 0.5 inch shank diameter. The 37-degree helix angle and ZrN (zirconium nitride) coating reduce built-up edge and improve chip evacuation in aluminum alloys. Built from submicron carbide grade, this end mill delivers consistent tool life in demanding production environments. It is a single-end, right-hand cut, right-hand flute tool with upcut flute geometry. Licensed machinists and CNC operators are the primary users.

The GWS 101011 belongs to the 1025 Alumigator series, which is engineered specifically for aluminum and soft non-ferrous alloys. It is well suited for high-speed machining in both production shops and job shops running CNC machining centers or manual mills. The centercutting capability allows plunge entry without a pre-drilled pilot hole, supporting full 3-axis toolpath strategies. Typical applications include profiling, slotting, and ramping in aluminum workpieces where chip packing and material adhesion are primary concerns.

Key Features

• 0.5 inch diameter with 2.25 inch length of cut for deep-reach aluminum milling
• 3-flute geometry optimizes chip clearance in aluminum and soft non-ferrous materials
• 37-degree helix angle promotes smooth cutting action and reduces chatter
• ZrN coating resists aluminum adhesion and extends tool life between regrinds
• Submicron solid carbide construction provides hardness and edge retention
• Centercutting design enables direct plunge entry without pilot drilling

Compatibility

Part of the GWS 1025 Alumigator series, designed for milling aluminum and non-ferrous alloys. Compatible with standard 0.5 inch collets, ER collet chucks, and end mill holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and power locked out. Ensure the shank is clean and the holder is torqued to the toolholder manufacturer's specification before use. Verify runout with a dial indicator after seating; excessive runout will accelerate edge wear and reduce surface finish quality. Consult the machine tool and toolholder manufacturer guidelines for appropriate clamping length and overhang recommendations.
