Kelvin Power Tools have a variety of SDS Max demolition hammers on sale, from top brands like Bosch and Metabo. These machines are used for all on site chiselling and light demolition jobs in concrete stone and masonry. You have the choice of lightweight and more heavy-duty models, giving the professional user the maximum choice when it comes to selecting the right tool for the job.
SDS stands for "Special Direct System" and describes the bit clamping system in these machines. SDS-Max is the most heavy-duty of all the SDS classifications, and SDS Max breakers are the heaviest of these. SDS-Max shanks measure 18mm and have 3 open grooves and locking segements. The shank and chuck design makes accessory changing quick and easy, as you only have to push the bit in and it locks in place. The design 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.
