The BLACK+DECKER BEHS01K-QS is a drill that you can use for 3 different types of jobs: drilling, hammer drilling, and chiseling. This makes the 650W combi hammer the right tool for the devoted DIYer who plans on doing more than just drill holes. The impact force of 1.4 joules is enough for light demolition work, such as breaking down a tile wall or a plaster wall. You attach drills heads or chisels in the SDS-Plus chuck. This type of drill head prevents your drill from coming loose during heavy work. Finally, in addition to a case, the BEHS01K-QS also comes with a side handle. You can adjust this to the angle in which you're working for a good posture. Or, take it off completely if you don't need it.
