Pneumatic Prop Rib Bolter
Designed on the base of our original portable pneumatic drilling machine.
Advantages: easy operation, stable action, and no anti-torque through prop supporting the body weight. Comparing with the portable pneumatic drilling machine, it has larger torque and power.
Especially used for drilling hole in hard coal tunnel and coal-rock tunnel with strong hardness.
