SDS stands for "Special Direct System", which describes the bit clamping system that is used on these concrete breakers. SDS-Max is the most heavy-duty SDS classification, with SDS-Max demolition hammers being the heaviest tool within this category. SDS-Max shanks are 18mm long, and have 3 open grooves and locking segments.
This shank and chuck design makes accessory changing quick and easy, as you simply push the bit in and it locks in place. It also allows the bit to move backwards and forwards freely, which means that the chuck doesn't need to be moved as much and the hammer can provide more power with less effort from the user.
These SDS concrete breakers are suitable for light demolition jobs. If you are conducting more substantial demolition tasks, then our range of heavy road breakers might be a better choice.
