Abstract (en)

[origin: EP0392201A2] 1. For anchoring anchor bolts, impact tools which can be clamped, inter alia, in drill hammers and impact drilling machines are known. 2. To prevent the impact tool from falling off on lowering the drilling machine and to improve the fixing of the impact tool to the expanding sleeve, an impact tool having a tubular adaptor part on the inside of which a drilling-head receptacle is situated is proposed, the adaptor part being partially covered by a sleeve, through which the drill is guided into the adaptor part. <IMAGE>
