The Arch•Master is the ideal silo and bin cleaning solution for material that tends to “arch” or “bridge” across the whole vessel.

This tough, portable, miniaturized rock drill was designed to create flow channels (up to 150’ or 45m deep) in arched or bridged material. In some cases, this may be all that is required. In other instances, the Junior 360º™ may be required.

Perfect for DIY cleanout projects involving bridged materials, the Arch•Master is the optimum choice for a fast and safe return to full material flow.
