Hammerhead® Moles

Catamount

The revolutionary Catamount line of piercing tools from HammerHead offers the industry a reciprocating head tool that is easy to start, regardless of air pressure level, and is the first pneumatic piercing tool head effective in both hard and soft soil conditions.

HammerHead designed the Catamount so the head is driven by air that resets the head, eliminating the need for mechanical springs, which are a common source of failure in trenchless tool designs. This design allows for a faster and easier start by eliminating the need to overcome recoil found in competitive models. The Catamount design takes full advantage of reciprocating head technology by increasing production rates in all soil types and also reduces tool swim at any operating pressure.

The Catamount design features a one-piece body made of heat-treated alloy steel versus welded or tubular construction. This design allows HammerHead to use a much heavier striker, increasing overall impact force. The one-piece body also provides better durability and tool life.

The Catamount tool line is currently available in 2.5″ to 5.125″ (64mm to 130 mm) diameter tools.
