Gws 311505 Square End Mill 5/16 in 5 Flute Solid Carbide

Product Description

The GWS 311505 is a solid carbide square end mill engineered for high-performance milling in demanding shop environments. With a 5/16-inch cutting diameter, 1-inch length of cut, and five flutes ground from submicron carbide, this tool delivers clean material removal and extended tool life compared to standard-grade carbide options. The AlCrO-MAX coating reduces heat buildup and resists oxidation at elevated cutting temperatures, making it well suited for ferrous metals, hardened steels, and abrasive alloys. It is a single-end, right-hand cutting, right-hand flute tool with a 38-degree helix angle and upcut flute geometry. Licensed machinists, tool-and-die shops, and CNC operators are the typical end users.

The GWS 311505 is designed for use in CNC machining centers and manual milling machines where tight tolerances and fine surface finishes are required. The 5/16-inch shank diameter matches the cutting diameter, allowing direct installation into standard collets or end mill holders without a reducer. Its 3-inch overall length and standard length designation make it a conventional reach tool appropriate for most profiling, slotting, and side-milling operations. The Series 2205 designation places it within GWS's line of high-performance coated carbide end mills built for production use.

Key Features

• Five-flute geometry increases feed rates and improves surface finish compared to four-flute designs
• AlCrO-MAX coating provides oxidation resistance and hardness retention at high cutting temperatures
• 38-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Submicron carbide grade delivers enhanced toughness and wear resistance
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute, upcut configuration suits standard CNC milling setups

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard 5/16-inch collets or end mill holders. Part of GWS Series 2205 high-performance coated carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or tool holder to the recommended grip length before tightening; insufficient engagement reduces tool life and risks tool pull-out. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Follow the machine manufacturer's guidelines and applicable shop safety procedures when setting cutting parameters.
