Brainard Killman BK-81

The BK-81 high rotary drive rig bores hollow stem augers to depths of 250 ft. with over 20,000 ft. lbs. of torque, soil conditions permitting.

This rig is equipped to perform mud rotary drilling and advance casing as drilling conditions warrant. With its additional clearance, the BK-81 can access most difficult sites, generally without the assistance of winches and bulldozers. This ability provides more choices and options at a difficult access project site.
