<p>The tool has connecting piece (2) that connects the tool with mold along direction of action of connecting piece connected to mandrel (4). A cover (6) covers the mandrel located in casing (7) made of reversibly deformable material under pressure. The mandrel is located between connection piece and cover, and a cavity (8) is located around the mandrel. Geometry of cavity is set such that casing is bulged locally under action of pressure along direction of action in cavity so that blind hole is formed in mixture (1) in bulged state. An independent claim is included for a method for creating blind hole in flowable and hardenable mixture.</p> |
