Gws 315039 Square End Mill 3/4 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 315039 is a solid carbide square end mill designed for high-performance milling in a range of metalworking and machining applications. Built to Series 2030 standards, it features a 3/4 inch mill diameter, a 4 inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation. The ZrN (zirconium nitride) coating reduces friction and extends tool life in demanding cutting environments. With three flutes, a right-hand cutting direction, and a right-hand flute direction, this end mill is suited for profiling, slotting, and peripheral milling operations performed by machinists and tool-and-die professionals.

This end mill is intended for use in CNC machining centers and manual milling machines where a single-end, center-cutting tool is required. The 3/4 inch shank diameter fits standard collets and tool holders in that size range. The 7 inch overall length provides extended reach for deeper setups without sacrificing rigidity due to the submicron carbide grade used in its construction. It is well suited for ferrous and non-ferrous material removal where a ZrN-coated tool offers an advantage over uncoated carbide.

Key Features

• Solid carbide submicron grade construction for wear resistance and rigidity
• ZrN coating reduces friction and extends tool life in production cutting
• 37-degree helix angle promotes efficient chip evacuation during slotting and profiling
• Center-cutting design allows plunge entry as well as peripheral milling
• Right-hand cut and right-hand flute direction for standard CNC and manual spindle operation
• Single-end configuration with 3 flutes for balanced chip load per tooth

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual milling machines accepting a 3/4 inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or tool holder to the minimum recommended grip depth to prevent pullout under cutting loads. Verify runout with a dial indicator before beginning a production cut.
