Cleveland Golf HSS End Mill 5/8 Inch

The Cleveland Golf HSS end mill is a general-purpose cutting tool machined from high-speed steel with a bright uncoated finish. It features a 5/8 inch milling diameter and a 5/8 inch shank for direct tool-holder fitment. The single-end square profile carries four right-hand flutes at a 30-degree helix angle for finishing operations. Overall length measures 3-3/4 inches with a 1-5/8 inch length of cut.

Installation and Common Issues

The tool installs by clamping the straight shank into a compatible collet or end-mill holder; no additional hardware is required. Run-out should be checked after tightening to prevent vibration and premature wear. Common problems include chatter if the tool overhang is excessive or if feed rates are mismatched to the material. The uncoated surface demands adequate coolant or lubrication to avoid built-up edge on sticky alloys.

Suitability and Alternatives

This end mill suits machinists finishing slots, pockets and profiles in mild steel, aluminium or plastic where a square corner is required. The fractional-inch dimensions match legacy tooling setups and manual milling machines. Buyers needing longer reach, corner radii, or coated performance for high-temperature alloys should evaluate other geometries. The single-end design limits economy for high-volume production where double-ended tools reduce change-over time.

Questions about this item

How can I verify the 30-degree helix angle is cutting correctly after setup?

Listen for smooth, consistent chip evacuation and check that the finished surface shows even marks without chatter at the recommended feed rate.

What accessories are included with the single-end mill and what must be sourced separately?

The tool itself is supplied alone; a compatible 5/8-inch tool holder, coolant supply and work-holding fixtures must be purchased separately.

Which end-mill configuration suits finishing passes in steel?

The four-flute, square-end, right-hand-cut design with a 30-degree helix and bright finish is intended for finishing operations.
