DUO-S Impact Drill Bit

DUO-S carbide-tipped bits for a percussion drill in brick, block and limestone. The Vario lines are the long-reach ones, for going right through a wall.

• Check before ordering: these are for a percussion drill, not an SDS hammer — SDS bits have a different shank and will not fit a keyless chuck. In hard Maltese stone let the bit cut at its own pace; leaning on it burns the carbide off.
