Cleveland Golf End Mill HSS TiCN 3/16 4 FL SGL Sq End

General-purpose finishing end mill

This Cleveland Golf square end mill is made from high-speed steel with a TiCN coating for general-purpose finishing work. The fractional-inch cutter has a 3/16-inch milling diameter, four flutes, and a single-end design. It suits machinists and fabricators who need a standard right-hand cutting tool for light production or maintenance milling.

Cutting geometry and material limits

The 30-degree helix angle and zero corner radius produce a sharp square profile for finishing passes in steel, cast iron, and non-ferrous metals. High-speed steel substrate limits cutting speeds compared with carbide, so the tool works best on manual or lower-rpm machines where toughness outweighs maximum feed rates. TiCN finish adds wear resistance but does not change the base material constraints.

Straightforward holder fitment

A 3/8-inch shank fits common collets and end-mill holders without adapters. Overall length of 2-3/8 inches and 1/2-inch length of cut keep overhang short for rigidity. The main installation issue is excessive run-out from worn collets, which accelerates flank wear on the HSS flutes. Verify holder condition before use.
