Abstract (en)
For use in mineral cutting the invention provides a point attack pick (20) which can be used in a forward attack pick box (18) alternatively to a forward attack pick (2). The point attack pick is made in two parts comprising an adaptor part (22) and a cutter part (32). The adaptor part fits the pick box and has a socket (30) in its forward end. The point attack cutter part has a shank which is received rotatably in the socket. The radial projection distance of the heads of the alternative picks in the pick box is substantially the same. The two forms of pick can thus be exchanged easily to suit changes in cutting conditions without adjusting the settings of the cutting machine. <IMAGE> <IMAGE>
