Gws 315027 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The GWS 315027 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. Built from submicron-grade solid carbide, this single-end tool features a 3/4 inch cutting diameter and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. With 3 flutes and an uncoated bright finish, the 315027 is suited for applications where coating buildup is a concern or where the base carbide substrate is preferred. Machinists and tool-and-die professionals working in job shops, production floors, and maintenance environments rely on this geometry for slotting, profiling, and peripheral milling.

This end mill fits standard 3/4 inch collets and tool holders commonly found on CNC machining centers and manual knee mills. The 3-1/4 inch length of cut allows access to deeper pockets and stepped features without requiring extended-reach tooling. With a 6 inch overall length and right-hand cutting and flute direction, the 315027 is a practical choice for ferrous and non-ferrous material removal where a standard-configuration, high-performance carbide tool is required. The centercutting capability allows it to plunge directly into a workpiece.

Key Features

• 3/4 inch mill diameter with matching 3/4 inch shank diameter for balanced clamping
• Submicron-grade solid carbide construction for wear resistance and edge retention
• 37-degree helix angle promotes chip lift and reduces cutting forces
• 3-1/4 inch length of cut for deep pocket and profile work
• Centercutting design enables direct plunge entry into material
• Bright/uncoated finish - no thermal barrier layer, suitable for applications requiring bare carbide

Compatibility

Designed for use in standard 3/4 inch collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a right-hand, single-end square carbide end mill.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the tool holder - insufficient engagement increases runout and risk of tool pull-out. Verify that the collet or holder is clean and free of chips or debris before clamping.
