Gws 101028 Square End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The GWS 101028 is a single-end, square-profile solid carbide end mill designed for high-performance milling operations. It features a 5/16 inch (0.3125 inch) mill diameter, a 7/16 inch (0.4375 inch) length of cut, and a 37-degree helix angle. The submicron carbide grade and bright/uncoated finish make this tool well-suited for aluminum and non-ferrous materials where edge sharpness and chip evacuation are critical. Machinists and tooling technicians use this end mill in CNC machining centers and manual mills where precision slotting, profiling, and contouring are required.

This end mill is part of the GWS Alumigator Series 1026, a line engineered for aluminum and soft metal cutting applications. The 3-flute geometry supports efficient chip clearance in aluminum without chip packing. With an extended reach design, a 2-1/8 inch reach length, and a 4 inch overall length, it handles deeper cavities and stepped features that standard-reach tools cannot access. It is appropriate for both production shop and job shop environments running aluminum, brass, copper, and similar non-ferrous workpiece materials.

Key Features

• Solid carbide construction in submicron grade for improved wear resistance and edge retention
• 37-degree right-hand helix with upcut flute geometry promotes chip evacuation in non-ferrous materials
• 3-flute design balances chip clearance and cutting performance in aluminum and soft metals
• Extended reach with 2-1/8 inch reach length for deep cavity and step milling
• Bright/uncoated finish maintains sharp cutting edges for aluminum applications where coatings can cause built-up edge
• Center-cutting capable, allowing direct plunge entry into workpiece material

Compatibility

Designed for use in standard CNC or manual milling machines accepting a 5/16 inch straight shank. Part of the GWS Alumigator Series 1026 tooling line intended for aluminum and non-ferrous milling applications.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle fully stopped. A properly sized collet or end mill holder with the correct 5/16 inch bore is required to ensure concentricity and prevent runout. Follow the machine tool manufacturer's recommended clamping torque for the holder type in use. Confirm cutting direction is set to right-hand rotation before operation.
