SDS-Plus Rotary Hammer Drills

Kelvin Power Tools have a wide range of SDS-Plus drills available from top manufacturers such as Bosch, Metabo Makita and Dewalt. These are the best tools for the heavy duty drilling of holes from 5.0mm to 30.0mm diameter in brick, masonry and concrete.

SDS stands for "Special Direct System" and describes the bit clamping system in these machines, and SDS-Plus is the most common form of this system. The 10mm drill bit shanks have 2 open grooves held by driving wedges, and 2 closed grooves held by 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.

The rotation stop feature available on most SDS-Plus machines means that they are also suitable for light chiselling applications when used with an SDS Plus chisel attachment. Our SDS-Plus hammer drill range contains machines suitable for electricians, joiners and all professional users.
