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： In an explosive charge-driven fastening element setting gun having a casing and a muzzle tube axially displaceably mounted in the casing, a damping housing is arranged to receive explosive gases passing laterally out of the gun. The damping housing surrounds the gun and is formed of two parts, one fitting into the other in a telescoping manner. One part is attached to the muzzle tube and the other part is fixed to the casing. Packing is secured to one of the parts and extends into contact with the other part in the region where the parts are telescopically fitted together.
