Cobalt Square End Mill

The Cleveland Golf Cobalt Square End Mill is a single-end fractional-inch cutter designed for general-purpose finishing. Its cobalt substrate and TiCN coating provide wear resistance across a range of materials.

Suited for finishing operations

Machinists performing right-hand finishing cuts with a 30-degree helix will find this four-flute tool appropriate. It is not for roughing passes, left-hand cutting requirements, or applications needing a corner radius or ball-nose profile.

1/8 inch diameter with 3/8 inch cut length

The 1/8 inch milling diameter and 3/8 inch length of cut handle shallow finishing passes in slots or pockets. Overall length of 2-5/16 inches limits reach in deep cavities, and the .000 corner radius leaves a sharp internal corner.

Questions about this item

What size collet or holder do I need for the 3/8 in. shank on this end mill?

Use a 3/8 in. collet or tool holder that matches the shank diameter exactly.

Will the 30-degree helix angle cause chatter when I run this tool in my older manual mill?

The 30-degree helix is a general-purpose geometry; it runs smoothly on both manual and CNC machines if feed and speed are set for cobalt.

How can I confirm the TiCN coating is intact after the first few cuts?

Inspect the flutes — the coating should show a uniform gold-grey colour with no bare cobalt visible at the cutting edges.
