A motor driven hand power tool has a saw including a saw blade, a separating tool formed as a saw blade movable about a tilting axis extending parallel to a cutting line of sight and fixable in each turning position relative to a workpiece which is subdivided by a cutting joint into a product-side and a refuse-side with product and refuse-side cutting edges, a base plate over which the saw blade is positioned. The saw blade is arranged so that the tilting axis extends at a distance under a lower side of the base plate, and the distance is dimensioned so that the tilting axis in a working position of the power tool is located under an upper surface of the workpiece in an interior of the workpiece.

Hand power tool with turnable base plate

Device on portable machine tools

A hand held power tool, particularly a hammer drill has a housing, a drive shaft, a rotatable tool holder, a safety coupling provided between the drive shaft and the tool holder, and a switching member supported with a bearing axis extending substantially parallel to the drive shaft and freely movable about the bearing axis in a plane extending substantially perpendicularly to the drive shaft. The switching member during a rearward rotation of the housing about an axis of the tool holder engages in the safety coupling and releasing the safety coupling.
