An application tool, in particular a chisel or a drill bit, is disclosed. The application tool has a tool head. The application tool further has a shank region in which a main body is arranged, wherein the main body has a first hardness. The application tool further has a coating that has a second hardness greater than the first hardness. The coating includes a hard metal, which comprises a hard material and a metal matrix. Advantageously, the durability of the application tool can be increased as a result.

Chisel and method for producing a chisel

A drilling tool, in particular a rock drilling tool, for a portable machine tool, includes an axis of rotation, at least one spiral path, and at least one wear surface transition. The at least one spiral path is coiled about the axis of rotation along the axis of rotation and includes at least one wear surface having at least one bandwidth. There is a change in the at least one bandwidth of the at least one wear surface at a position of the at least one wear surface transition.

Drilling tool

A drill bit includes a tool body having a main body in the form of a cylinder. A chip removing structure is provided on the main body. The tool body has a distal end provided with a clamping slot and a cutter inlaid in the clamping slot. The cutter has at least two blade portions arranged circumferentially on the distal end of the tool body and extending radially relative to the tool body. Each of the blade portions has a front side along the drill bit's rotating direction and a back side against the rotating direction. The clamping slot covers the back side of one blade portion by an area larger than that used to cover the front side of the same blade portion.
