When doing any construction work it is essential to have the right tools.
The first tool to be purchased is an “Hitachi DH38MS 950W SDS-Plus Hammer Drill”.This drill has 2 settings, one for hammer drilling and a hammer only option which can be used with SDS plus masonry chisels.
This is a great tool for breaking up concrete and digging holes in the ground which has a high concentration of stones (like in the kellar at the house in Joehstadt).
