The Pengo drill bucket is redesigned with a heavy-duty hinge, large radial vent and patent-pending Cam actuated plunger rod. It couples an automatic and manual trip-release for easier use on both European and conventional drill rigs. The double cutting bottoms are available with interchangeable rock and dirt heads that have auto-close actions. The Pengo drill bucket is also designed for use with kelly boxes from 4 inches to 200 millimeters and can be customized for special drilling needs.
