Gws 310154 Square End Mill 5/16 in 4 Flute Solid Carbide

Product Description

The GWS 310154 is a solid carbide square end mill engineered for demanding metal removal applications in professional machining environments. Measuring 5/16 inches in diameter with a 7/16-inch length of cut and a 2-inch overall length, this single-end tool delivers precise, repeatable performance in CNC and manual milling operations. The 4-flute geometry and 38-degree helix angle promote efficient chip evacuation and reduce cutting forces. An AlCrO-MAX coating adds heat and wear resistance, extending tool life in ferrous and non-ferrous materials. Machinists and tooling technicians working in production shops or job shops will find this tool suited for finishing and semi-finishing passes.

This end mill fits standard 5/16-inch collets and tool holders, making it compatible with a wide range of vertical and horizontal milling machines. The square shank and right-hand cutting direction make it a straightforward drop-in for right-hand spindle setups. Typical applications include slotting, profiling, and peripheral milling in materials where thermal stability and edge retention are critical. The Series 2100 designation places it within GWS's submicron carbide grade lineup, targeted at shops running higher-speed, tighter-tolerance work.

Key Features

• 4-flute, right-hand upcut geometry for efficient chip flow and smooth finish
• 38-degree helix angle reduces cutting pressure and vibration
• AlCrO-MAX coating provides oxidation and wear resistance at elevated temperatures
• Submicron carbide grade for improved toughness and edge retention
• Single-end design; 2-inch overall length suits standard reach applications

Compatibility

Designed as an OEM-style replacement or direct substitute for 5/16-inch square end mills in standard collet-based milling setups. No specific model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Use the appropriate collet or end mill holder torqued to the machine manufacturer's specification. Inspect the tool shank and collet bore for debris or damage before seating the tool.
