The purpose of this study are determine drilling process of a bucket excavator and observe the result of drilling on a line drilling machine. The research used a drilling line TPX6113 type that the chisel is YG6. Drilling process is carried out with three feeding process, namely 4mm, 2mm and 2 mm that the feeding speeds are 20 rpm and 31.5 rpm. The result is the smoothest process drilling in the high speed
