摘要： The cutting plate 12 includes a base body 22 made of a sintered hard metal. On a top side 23 of the base body 22 there are one or multiple intermediate layers 25 that include an adhesion-promoting layer 26. The adhesion-promoting layer 26 is made of a boron-containing nitride of a transition metal of group IV, group V, and group VI, and contains a plurality of small plates 31 oriented at an angle relative to the top side 23. A diamond layer that is grown on the adhesion-promoting layer 26 includes stalk-shaped crystals, oriented vertically relative to the top side 23, having an aspect ratio greater than three.

摘要： A hand-held power tool is disclosed. The tool has a pneumatic striking mechanism. The striking mechanism includes a motor-driven exciter, a guide tube and a striker. A pneumatic spring configured inside the guide tube between the exciter and the striker is circumferentially sealed pressure-tight by an inner surface of the guide tube. The exciter and/or the striker are configured as a piston guided by the inner surface. An inner surface of the guide tube is provided with a plurality of molded depressions.
