Cleveland Golf HG-4C Square End Mill

The Cleveland Golf HG-4C is a general-purpose square end mill made from high-speed steel. It is designed for machinists and fabricators who need a reliable tool for finishing operations in a range of materials.

Bright finish 1-1/4 inch shank and four flutes

The tool features a bright uncoated finish, a 1-1/4 inch shank diameter and four flutes with a 30-degree helix angle. Its single-end design and right-hand cutting direction fit standard milling holders, while the 2-inch length of cut provides reach for deeper slots or profiles.

Replaces worn uncoated HSS finishing cutters

This end mill upgrades from dull or damaged high-speed steel finishing tools with a 0.000 inch corner radius. The jump is worthwhile when a sharp, square-corner profile is needed for final-pass accuracy on manual or CNC mills.

Questions about this item

How does the 30-degree helix angle affect chip evacuation during deep slotting?

The 30-degree helix provides a balance between chip removal and edge strength, helping clear chips from the 2-inch length of cut without excessive vibration.

Does the bright uncoated finish cause the tool to run hotter in steel than a coated version would?

The uncoated high-speed steel surface generates more friction and heat in steel, so flood coolant or reduced speeds are recommended for extended cuts.

What tool holder is required for the 1-1/4-inch straight shank?

A standard 1-1/4-inch end-mill holder, collet chuck, or Weldon-style holder with a matching bore is needed to secure the shank.
