General-Purpose HSS End Mill

The Cleveland Golf square end mill is made from high-speed steel for general-purpose finishing operations. It suits machinists and maintenance workshops that need a reliable cutter for slotting, profiling and light material removal in ferrous and non-ferrous metals.

Bright Uncoated 30-Degree Helix Tool

The bright uncoated finish and 30-degree helix angle limit performance in abrasive or high-temperature alloys where coated carbide tools would last longer. The .000 corner radius leaves a sharp corner that can chip in interrupted cuts, and the two-flute design restricts chip evacuation in deep slots or heavy roughing passes.

Straightforward 3/8-Inch Shank Mounting

The 3/8-inch straight shank fits standard end-mill holders and collets without adapters, and the 2-1/2-inch overall length clears most machine envelopes. The most common error is running the 9/16-inch length of cut beyond the flute length, which causes deflection and poor surface finish, while excessive feed rates on the uncoated flutes accelerate wear.

Questions about this item

Should I choose the 5/16 inch diameter or a different size for finishing work?

Select the 5/16 inch diameter when your design calls for that exact slot width; the 9/16 inch length of cut and 3/8 inch shank fit standard holders for finishing passes.

What does the 30 degree helix angle mean once the cutter is in the machine?

The 30 degree helix gives a moderate shear angle that evacuates chips smoothly while keeping vibration low during finishing cuts in steel or aluminium.

How does the bright uncoated finish affect tool life and cutting speed limits?

Without a coating the high-speed steel edge runs cooler in shallow finishing passes but wears faster if pushed to aggressive speeds or used in abrasive alloys.
