Abstract
A mineral cutter pick and its pick box are secured together through a spigot and socket connection. Opposed end faces of the pick and holding device that surround the connection have laterally oppositely inclined surfaces at opposite sides of a central plane of the pick extending in the direction of cutting movement. These complementary inclined faces improve the load distribution between the pick and its locking device in use and can also be arranged to restrict the entry of foreign matter into the spigot and socket connection.
