Automatic Driller / Satellite Automatic Driller

Satellite Automatic Driller

Our satellite automatic drillers have shown to be the most reliable auto driller on the market today. They are a state-of-the-art drilling technology that is capable of automatically maintaining the proper weight on a bit. The technology works by sensing the deadline tension and (automatically) correcting the weight on the bit. Our automatic drillers have also proven to reduce driller fatigue.
