Cleveland Golf 1/2 in 4-Flute Square End Mill HSS

Cleveland Golf 1/2 in HSS End Mill

This square end mill is a high-speed steel cutting tool designed for general-purpose milling operations. It features a 1/2 inch cutting diameter and a matching 1/2 inch shank with a Weldon flat for secure toolholder retention. The bright, uncoated finish is suitable for a variety of ferrous and non-ferrous materials. It serves machinists and maintenance workshops requiring a standard single-end profile.

Installation uses a standard Weldon flat shank

The 1/2 inch shank with Weldon flat locks into compatible end mill holders using a set screw, providing a rigid, non-slip connection for heavy cuts. Ensure the holder bore matches the shank diameter exactly and that the set screw engages the flat cleanly to prevent pull-out. The 3 1/4 inch overall length fits many standard toolholders, but verify machine spindle clearance before mounting. A common issue is insufficient set screw torque, which allows the tool to shift under load and damage the workpiece or holder.

Suited for general milling in steel and aluminium

This tool suits machinists performing slotting, profiling, or facing cuts where a square corner is required. The four-flute design offers good surface finish and chip evacuation in moderate production runs. It is less suitable for high-volume production where coated carbide tooling would extend tool life significantly. Buyers needing extended reach, corner radii, or ball-nose profiles for contouring should look at alternative geometries.
