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 demolition hammers are the heaviest of these. SDS-Max shanks measure 18mm and have 3 open grooves and locking segments.
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. This means the chuck doesn't need to be moved as much and the drill can provide more power with less effort from the user.
If you want to know more about an SDS breaker or any other power tools please feel free to contact us. We have an excellent team of power tool experts who are happy to help you.
At Kelvin Power Tools we supply road breakers as well as these SDS breakers. The SDS versions are suitable for light demolition jobs but if you have a more substantial demolition task, a concrete breaker might be the better choice. You can have a look at our range of heavy breakers.
