Gws 314531 Square End Mill 3/16 in 3 Flute Solid Carbide

Product Description

The GWS 314531 is a solid carbide square end mill designed for high-precision milling operations in metal, composites, and engineering plastics. With a 3/16-inch cutting diameter and a 3/4-inch length of cut, this single-end tool handles slotting, profiling, and peripheral milling in tight geometries. The 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from submicron carbide grade material, the 314531 delivers consistent edge integrity and extended tool life compared to standard carbide grades. The bright, uncoated finish suits a wide range of work materials where coating interaction is a concern. Machinists and tool-and-die professionals will recognize this as a dependable production-grade option for precision work.

This end mill is suited for use in CNC machining centers, knee mills, and manual milling machines where a 3/16-inch shank is required. The 2-1/2-inch overall length keeps the tool compact for improved rigidity in close-tolerance cuts. Right-hand cut and right-hand flute direction are standard for conventional and climb milling setups. The upcut flute geometry and centercutting capability allow plunge entry, making it versatile across a range of milling strategies including ramping and helical interpolation. It fits standard ER collets and end mill holders that accept a 3/16-inch shank.

Key Features

• 3/16-inch cutting diameter with matching 3/16-inch shank for direct collet clamping
• 3/4-inch length of cut accommodates moderate-depth slotting and profiling passes
• 37-degree helix angle for efficient chip evacuation and reduced cutting forces
• Submicron solid carbide grade for superior edge retention and wear resistance
• Centercutting design allows direct plunge entry without pre-drilling
• Bright, uncoated finish compatible with a broad range of work materials and cutting fluids
• Right-hand cut and right-hand flute direction for standard milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC and manual milling applications requiring a 3/16-inch shank diameter end mill. Fits standard ER-11 and ER-16 collet systems as well as end mill holders sized for 3/16-inch shanks.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the end mill. Secure the shank to the recommended collet engagement depth per the tool holder manufacturer guidelines. Verify runout with a dial indicator before beginning production cuts to protect edge life and part accuracy.
