摘要： The invention is a striking mechanism for a handheld power tools in particular electric hammer. A piston is arranged in an axially bidirectionally movable manner in a guide tube. A striker is provided which acts on a striking pin and which is held in a movable manner in the guide tube. A compression space is delimited by the piston and the striker such that an air cushion is enclosed therein. It is proposed that at least one spring element is provided between the striker and the striking pin.

摘要： A drilling tool has a drilling shaft member, a crown drilling member with an annular wall provided with a plurality of cutting edges and detachably mounted on the shaft member, a center drilling member detachably mounted on the shaft member inside the crown drilling member and having a further cutting edge, and elements for limiting a drilling depth of the tool when the center drilling member is mounted on the shaft member. Thereby, the operator of the drilling tool, after drilling a guiding groove in a rock, is forced to remove the center drilling member from the drilling tool and drill further without the center drilling member, which increases the drilling efficiency.

摘要： To apply hard cutting particles, for example of tungsten carbide, on the surface of the cutting edge of a cutting tool, such as a saw blade, a drill, or the like, the cutting edge is partially melted by an energy beam, for example a laser beam, or an electron beam. A laser beam is preferred since, then, the process can be carried out in air, or in a protective gas atmosphere, rather than in a vacuum. The beam partially melts the cutting edge and the granules of the hard metal particles, preferably in a random grain size of between 0.3 to 1.5 mm is permitted to run down, over the partially melted surface, excess being collected for reuse; alternatively, the partially melted surface can be dipped into the granules, and permitted to solidify.
摘要翻译：为了将诸如碳化钨的硬切割颗粒施加在诸如锯片，钻头等的切割工具的切割边缘的表面上，切割边缘被能量束部分地熔化，例如激光束或电子束。激光束是优选的，因为该方法可以在空气中或在保护气体气氛中进行，而不是在真空中进行。梁部分地熔化切割边缘，并且允许在0.3至1.5mm之间的随机晶粒尺寸的硬质金属颗粒的颗粒在部分熔融的表面上向下运行，多余的被收集用于再利用; 或者，部分熔融的表面可以浸入颗粒中并允许固化。

摘要： A chuck for use in a percussion drill or the like has a unit for securing the chuck jaws against unintentional loosening during operation. The securing unit moves from an unlocked position in which a tool can be received by the chuck jaws to a locked position automatically for drilling operations without the use of a key. The securing unit includes a first surface (22) upon which a sliding member (21) is slidable to be received in a recess (26) during the shaking caused by drilling, so that coupling members (15, 19) between a securing sleeve (17) and a clamping sleeve (13) engage with one another.
