Gws 101013 Square End Mill 5/8 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 101013 is a solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. It features a 5/8 inch diameter, a 2-1/2 inch length of cut, and three right-hand flutes ground from submicron-grade carbide. A 37-degree helix angle promotes aggressive chip evacuation and reduces built-up edge. The ZrN (zirconium nitride) coating adds surface hardness and lubricity, extending tool life in high-speed aluminum applications. This end mill is a single-end, center-cutting tool suitable for plunging, slotting, profiling, and peripheral milling operations. It is installed and operated by machinists and CNC tooling professionals.

The 101013 is built for milling aluminum, composites, and other non-ferrous materials where chip packing and heat buildup are primary concerns. The Alumigator Series 1025 designation identifies it as a geometry optimized for aluminum finishing and roughing. With a 5 inch overall length and a 5/8 inch shank diameter, it fits standard ER and side-lock tool holders common in vertical machining centers and CNC routers. The upcut flute geometry pulls chips upward and out of the cut, keeping the work zone clear during deep-pocket and slotting operations.

Key Features

• 5/8 inch diameter with 2-1/2 inch length of cut for deep-pocket capability
• 3-flute, right-hand upcut geometry optimized for aluminum chip evacuation
• 37-degree helix angle reduces cutting forces and minimizes heat buildup
• ZrN coating increases surface hardness and extends tool life in non-ferrous applications
• Submicron-grade solid carbide blank for rigidity and edge retention
• Center-cutting design allows direct plunge entry without a pre-drilled hole

Compatibility

Part of the GWS Alumigator Series 1025, designed for aluminum and non-ferrous milling applications. Fits any tool holder accepting a 5/8 inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify tool holder runout with a dial indicator before operation, as excessive runout accelerates edge wear on carbide tooling. Follow the machine manufacturer and cutting tool manufacturer feed-and-speed recommendations for the specific workpiece material.
