Cleveland Cobalt Double-End Mill

The Cleveland Cobalt double-end mill is a general-purpose rotary cutter for milling machines. Its bright uncoated cobalt body suits metalworking shops and maintenance departments that need a replaceable tool for finishing passes in steel and similar alloys.

Finishing capacity with 1-5/8 in. cut length

The 1-5/8 inch length of cut provides reach for pocketing and profiling work on medium-depth features. Shorter flute length limits deep-cavity milling, so the tool runs out of engagement before the shank contacts the workpiece in taller parts.

30-degree helix for finishing cuts

A 30-degree helix angle and zero corner radius produce a smooth surface finish on right-hand rotation passes. The fixed geometry prevents use on roughing operations or materials that demand a variable-helix or chip-breaker design.

Questions about this item

Will the 3/4 in. shank fit the collet I already use on my mill?

The shank diameter is 3/4 in., so it matches standard 3/4 in. collets and holders.

How can I confirm the 30 degree helix is cutting cleanly after install?

Listen for a steady sound and check for consistent, uncoated chips with no chatter marks on the workpiece.

Does the double-end design ship with a protective sleeve or just the bare tool?

The tool arrives as a single bright-finish double-end mill; no sleeve, holder or coating is included.
