Differences Between Uncoated and Coated Carbide Inserts

Coating technology is one of the biggest factors affecting carbide-tool performance. Many buyers are confused whether they should select coated or uncoated carbide inserts.

Uncoated carbide inserts: Best suited for low-speed machining, non-ferrous metals, titanium alloys and some hard-to-cut materials. Good toughness, lower cost.

Coated carbide inserts (AlTiN, TiN, TiCN): The thin coating layer works as a thermal-barrier. It allows much-higher cutting-speed, reduces friction and extends tool-life, ideal for mass-production steel machining.

Coated tools usually cost slightly more, but they deliver far better efficiency in high-speed continuous-cutting work.
