The Enz Mini Roto-Drill 1/4" is shorter than standard Root Cutting nozzles, so it can easily negotiate traps and bends. This nozzle has a rotating jet for improved cutting performance. Application The Enz Mini Roto-Drill 1/4" is highly effective for clearing blocked pipes, tree roots and debris in complex and difficult drain configurations due to its short length. It can be used to clean out blockages after traditional Mustang Penetrating and Invading Nozzles have begun the job. Please indicate your jetter pressure and flow in the 'Order Notes' section of the Shopping Cart.
