We stock a small range of SDS-Max concrete breakers from leading trade brands Bosch and Metabo. These demolition hammers have a special drill bit system which greatly improves power and efficiency; making them suitable for stone drilling, chiselling jobs, and breaking heavy-duty concrete and masonry.
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.
