The redesigned Combo Drill Bucket features a heavy-duty hinge, large radial vent, patent-pending cam-actuated plunger rod, and fully isolated actuator that’s not exposed to drilling spoils. Double cutting bottoms are available with interchangeable rock and dirt heads with auto-close actions. Designed for use with Kelly boxes from 4 in. to 200 mm, it can be built for special drilling needs. Pengo. 800-599-0211.
