Description

The A108 is a unique Dormer drill specifically designed for stainless steels. In order to adequately machine these materials, sharp tools are needed to limit the development of heat during drilling. That is why the A108 has a very positive, sharp geometry and a special chip groove, to quickly remove the tough chips from the hole. This drill is certainly the first choice when used in hand drills and other unstable conditions.
