Cleveland Golf HSS Double-End Mill

This Cleveland Golf end mill is a general-purpose square-end cutter made from high-speed steel. It suits machinists and fabricators who need a bright, uncoated tool for finishing passes in a range of ferrous and non-ferrous materials.

Practical limits of a 30-degree helix

The 30-degree helix angle provides a conventional balance between chip evacuation and edge strength for standard milling operations. A fixed right-hand cutting direction and zero corner radius mean the tool cannot produce radius profiles or climb-mill effectively in left-hand setups.

Double-end design with 5/8-inch shank

The cutter carries identical square ends on both sides of a 5/8-inch diameter shank, effectively providing two fresh cutting edges per holder changeover. This geometry only fits tooling that accepts a 5/8-inch shank and the stated overall length.

Questions about this item

Should I choose the double-end or single-end version of this 5/8 inch HSS end mill?

This tool is a double-end square end mill, giving you two cutting ends on one 5 inch shank. When one end wears, you flip the tool and continue machining without changing holders.

What does the 30 degree helix angle mean for chip evacuation in steel?

A 30 degree helix provides a balanced cutting action for general-purpose finishing. It lifts chips steadily from the 1-1/8 inch flute length without excessive vibration in a standard milling setup.

How does the bright uncoated finish affect tool life when milling mild steel?

The bright (uncoated) high-speed steel surface works well for finishing passes in softer materials. It avoids coating buildup on the 0.000 inch corner radius, keeping edges sharp for clean square-bottom cuts.
