Precision Cobalt End Mill

The Cleveland Golf Cobalt End Mill is a single-end, square-profile cutter designed for general-purpose finishing in ferrous and non-ferrous materials. Its two-flute geometry and 30-degree helix suit machinists and fabricators who need reliable chip evacuation on manual or CNC mills.

Thermal and Power Behaviour

As a solid cutting tool it generates heat only at the workpiece interface during milling passes. No electrical power is drawn and no active cooling system is required beyond standard shop flood or mist coolant.

Build Integration

The 3/8-inch shank fits standard ER collets, Weldon flats or end-mill holders without adapters. Bright uncoated finish keeps the tool economical for short-run jobs where frequent tool changes are preferred over premium coatings.

Questions about this item

How do I install the 3/16 in. end mill in a 3/8 in. shank holder, and what step is often missed?

Insert the shank fully into the collet or holder, then tighten evenly. The step often missed is verifying the 30-degree helix engages cleanly before starting the cut.

What maintenance or replacement will the cobalt square end mill need after extended finishing work?

The bright uncoated cobalt flutes will dull gradually; plan to resharpen or replace the tool once edge wear affects the .000 corner radius finish quality.

What limit appears first when running this 2-flute cutter at sustained feed rates in finishing passes?

Heat buildup in the uncoated cobalt body becomes the limiting factor, reducing edge life before deflection or chip evacuation becomes critical.
