Tool, cutter and button disk |
摘要 |
A tool for mining rock by means of undercutting includes an attachment part which defines a center longitudinal axis, and a holder mounted to the attachment part by bearings for rotation relative thereto about the axis. An outer surface of the holder includes a circumferentially extending first groove. A button disk is mounted on the cutter and includes an inner surface having a circumferentially extending second groove. One of the grooves is superimposed relative to the other groove to define therewith a space. A wire extends within the space to hold the button disk on the cutter.
