The quality of punching, forming and cutting tools can be significantly improved by machining them using a drag rolling process. A defined edge rounding gives an increased service life for cutting tools such as carbide drills, taps, turning inserts, smaller reamers, etc.

Drag tumbler is also used to polish tools both before and after coating. During coating, so-called “droplets” are formed. A quick polishing process after coating cutting tools gives a smoother surface finish and removes drips, which results in less friction and reduced tool wear.

Even tool holders can be advantageously polished in order to obtain a product with a more attractive appearance and to minimize the risk of corrosion.
