Abstract
A tool for removing a drill core is formed of a tubular tool member (1) having an axially extending receptacle region (A) and an axially extending gripping region (B), wherein the receptacle region (A) extends partially around half of the circular annular circumference. In a first end of the receptacle region (A) spaced from the gripping region (B) two mutually opposed swivel arms (4) are arranged. The swivel arms (4) project into the inside diameter of the tool member (1) and extend in the direction of the gripping region (G) and are elastic in the radial direction. These swivel arms (4) serve in axially securing a drill core received in the receptacle region (A) of the tool member (1).
