ABSTRACT:

In a gear case of a housing, there are provided a clutch switching groove which engages with a connecting projection of a clutch switching lever, a slit which guides a guide body having a stepped pin which penetrates an impact switching groove to engage with an auxiliary ring, and a percussion switching groove which engages with a connecting projection of a percussion switching lever. In addition, a switching case is externally provided, so that combination of sliding positions of each switching member can be changed. As the switching case can be operated by a switching button, any of all operation modes, which are, a drill mode, an impact mode, a percussion drill mode, and a clutch mode can be selected with the switching button only.
