How Do I Convert a Three-Jaw Drill Chuck to an SDS Drill?
A Special Direct System (SDS) hammer drill operates as a drill, a chisel, a hammer or as a hammer and drill motion combined. SDS drills are heavier than traditional drills with a deeper chuck and larger bits to accommodate heavy drilling and hammering in projects. An SDS chuck allows the drill bit to retract into the chuck for longer strokes in the hammer drill function. Longer strokes supply extra force to break through concrete, brick and other hard materials.
