Cobalt Square End Mill 1/2

The Cleveland Cobalt square end mill is a general-purpose milling cutter for ferrous and non-ferrous metals. It has a 1/2 inch cutting diameter with four flutes and a single-end design. The tool uses a bright uncoated finish and a 30-degree helix angle for finishing operations. Right-hand cutting direction suits conventional milling setups.

Verify Shank And Machine Compatibility

Confirm your holder accepts a 1/2 inch straight shank before ordering. The overall length is 3-1/4 inches with a 1-1/4 inch length of cut, so check spindle clearance and work envelope. Ensure the machine runs the correct speed range for cobalt tooling in your material. No coating means coolant or lubricant choice is critical.

Suited For General Finishing Passes

This cutter suits shops doing finishing work in steel, stainless steel or high-temperature alloys where cobalt resists heat. It is not for roughing passes that need chip-breaker geometry or coated tools for higher feeds. Buyers needing corner-radius profiles or ball-nose contours should select a different end-mill style.

Questions about this item

Does the Cleveland Cobalt end mill come with any holders or tooling accessories in the box?

The product is supplied as a single square end mill only; collets, holders, or other tooling accessories must be purchased separately.

When would I choose the 4-flute cobalt version over a 2-flute or coated alternative?

Choose the 4-flute cobalt tool for finishing passes in steel or stainless where the 30-degree helix and uncoated bright finish provide smooth chip evacuation and edge retention.

What surface finish can I expect from the 30-degree helix and bright finish on this mill?

The 30-degree helix and uncoated bright finish are designed for finishing operations, producing a smooth surface on the workpiece with minimal built-up edge.
