Cleveland Golf Cobalt End Mill 1/4 Inch

The Cleveland Golf HGC-4C is a cobalt square end mill built for general-purpose milling. Its 1/4-inch cutting diameter and four-flute design deliver smooth finishing passes. The 3/8-inch shank fits standard tool holders, and the 30-degree helix promotes stable chip evacuation. Bright uncoated finish keeps the edge sharp for non-ferrous and light steel work.

Best for finishing passes in softer metals

Machinists running finishing operations on aluminium, brass or mild steel will appreciate the four-flute geometry and zero corner radius. The single-end layout and 5/8-inch length of cut limit reach in deep cavities. Shops needing roughing profiles, coated tool life or extended reach should evaluate other tool styles.

Fits 3/8-inch holders and frees up tool changes

The 3/8-inch shank secures directly in common collets or end-mill holders without adapters. A 2-7/16-inch overall length clears most machine envelopes while keeping overhang short. Right-hand cutting direction matches standard spindle rotation, so the tool drops into existing CNC or manual setups with no reprogramming.

Questions about this item

What shank size must my tool holder accept for this 1/4 in. end mill?

The shank diameter is 3/8 in., so your collet or holder must grip that size.

Will the 30-degree helix angle work with the older manual mill I still use?

Yes, the 30-degree helix is a general-purpose geometry that cuts smoothly on both manual and CNC machines.

How can I confirm the cutter is running true after I install it?

Check that the bright uncoated flutes show even wear and the .000 corner radius leaves a flat-bottomed finish.
