U135 Mining Coal and Rock Pick, JZA80/38 Series Roadheader Pick. This pick is produced by Shandong Aide Industrial Co., Ltd. and serves as a cutting tool on roadheaders for directly breaking rock and coal. It is mainly used for drilling in coal mines and soft rock, as well as for cutting in tunnels, trenches, and open-pit mines. It is typically used together with the U135 pick holder and installed on the matching roadheader cutting head (boom head).
