摘要： A hollow drilling tool is made up of an axially extending tubular carrier part, a cutting body at one end of the carrier part, and guide elements located in the axial direction of the carrier part between the cutting body and the carrier part. The radially outer surface of each guide element is in alignment in the axial direction of the carrier part with the radially outer surface of the cutting body. The guide elements guide the hollow drilling tool in a borehole formed by the cutting body.

摘要： Fastening elements, such as bolts, studs or nails, are inserted into a hard receiving material, such as concrete or rock, first, by drilling a blind borehole into the receiving material. The diameter of the borehole is formed so that it is greater than the diameter of the leading end of the fastening element. A setting device containing the fastening element is then aligned with the blind borehole and the fastening element is driven into the receiving material. The fastening element enters the receiving material at the base of the blind borehole. The length of the fastening element inserted into the receiving material is at least half the axial length of the borehole and may have a length considerably greater than the axial length of the borehole.

摘要： A hollow crown drill has a set of cutting members (2, 3, 4) positioned on the leading or cutting end of an annular axially extending carrier member (1). The radial width of the cutting faces (2a, 3a, 4a) of the cutting members (2, 3, 4) increases opposite to the rotational direction (D) of the carrier member (1). In addition, the cutting members (3, 4) in the set disposed counter to the rotational direction (D) are offset in the direction parallel to the axis of the carrier member relative to the cutting member of the set leading in the rotational direction. This dimensional feature relates to the increase in the size of the cutting faces (2a, 3a, 4a). With the cutting faces (2a, 3a, 4a) dimensioned as above, each of the cutting members penetrates deep into the material being drilled, so that if the usual contact pressure forces are applied abrasive wear resulting in premature failure of the hollow crown drill does not occur.
摘要翻译：空心冠钻具有一组位于环形轴向延伸的承载构件（1）的前端或切割端上的切割构件（2,3,4）。切割构件（2,3,4）的切割面（2a，3a，4a）的径向宽度与载体构件（1）的旋转方向（D）相反地增加。另外，与旋转方向（D）相对设置的组中的切割构件（3,4）相对于沿旋转方向引导的组件的切割构件在平行于承载构件的轴线的方向上偏移。该尺寸特征涉及切割面（2a，3a，4a）的尺寸的增加。由于上述切割面（2a，3a，4a）的尺寸如上所述，每个切割构件深入到被钻孔材料中，因此如果通常的接触压力被施加磨损磨损导致中空冠钻的过早失效不发生

摘要： A manually guided motorized hand tool used for drilling and/or percussive drilling includes a housing with a mass movably mounted about the drilling axis for movement relative to the housing. A switch is mounted on the housing and is operable by the mass when it moves a certain angular distance relative to the housing. When operated, the switch cuts off the power supply to the hand tool.
摘要翻译：用于钻孔和/或冲击钻孔的手动引导的电动手动工具包括具有围绕钻孔轴线可移动地安装的用于相对于壳体移动的质量的壳体。开关安装在壳体上，并且当其相对于壳体移动一定角度距离时可由质量块操作。操作时，开关切断手动工具的电源。
