  • TiN coating extends tool life by reducing wear

Product identity

The Cleveland C39012 is a 2-flute high-speed steel ball nose end mill with a TiN coating for general milling tasks. It suits machinists and maintenance teams needing a reliable single-end cutter for profiling and contouring work.

Installation notes

The tool installs in any standard collet or chuck that accepts a .25 in shank and requires no coolant-through setup. Runout or vibration usually points to holder wear or incorrect speed and feed selection rather than the cutter itself.

Sustained load behaviour

The TiN coating reduces friction and heat buildup during extended cuts, helping the flutes stay sharp longer than uncoated HSS. Continuous heavy profiling will still wear the edges faster than carbide, so plan tool changes for long production runs.

Questions about this item

How can I confirm the Cleveland C39012 end mill is cutting correctly after setup?

Check for smooth, chatter-free cuts and a consistent surface finish on the workpiece; the TiN coating should show even wear without premature edge breakdown.

What comes with the Cleveland C39012 ball nose end mill and what must I supply separately?

The box contains the single 2-flute HSS ball nose end mill with TiN coating; you must provide a compatible tool holder, workpiece material, and cutting fluid if required.

Which version of the Cleveland C39012 should I choose for my milling diameter needs?

This model is offered in a .25 in milling diameter with a 2-flute HSS ball nose design and TiN coating; select it when that specific diameter and flute count match your application.
