SDS-Max Drills

The SDS-Max hammer drill selection from Bosch, Makita, Metabo and DeWalt, all stocked by Kelvin Power Tools. 

SDS stands for "Special Direct System" and describes the bit clamping system in these machines, and SDS-Max hammer drills are the most heavy-duty variety of this system. The 18mm drill bit shanks have 3 open grooves and locking segements rather than locking balls. This allows the drill bit to simply slip in and lock, no tightening needed, and it can be released just as easily. It also allows the bit to move backwards and forwards freely, meaning that the chuck does not need to be moved as much and the drill can provide more power with less effort from the user.

SDS-Max drills are 5kg upwards, dedicated to the purpose of drilling and chipping into concrete, stone and masonry and not intended for drilling into wood or other similar materials. With the use of an SDS-Max chisel attachment you can also perform fairly heavy-duty chiselling tasks with ease.
