Milling cutters  used for road surface  preparation see the most severe conditions of any tool in any application.

The barrels that support these tools and that the tool  are mounted to require a long changeover time. Usually there are from 170 to 200 cutters on one barrel,  in many cases all cutters may have to be changed daily and in almost all cases never last more than 3 days.
The process developed by TTS extends the life by 2.5 to 3 times saving significant monies.
