Pneumatic piercing tools from HammerHead Trenchless Equipment are designed for creating a compact hole for most underground installations with minimal disruption to landscape, buildings or traffic flow. The newest tools in HammerHead’s pneumatic line are 4- and 5.125-inch models with a Catamount reciprocating or a fixed, non-reciprocating head.

“The benefit of a pneumatic tool is it gives you an opportunity to do trenchless-type installations for a low purchase price,” says Chris Alexander, southeast regional manager of piercing tools for HammerHead.

Available in a variety of sizes and models, the piercing tool can be used in diverse ground conditions and serviced in the field.

“The replaceable head tool was originally designed for softer soil conditions,” he says. “The reciprocating head in the Catamount design is for harder soil conditions.”

The new models feature the Power Port quarter-turn reverse design that pneumatically locks into forward or reverse, preventing accidental direction change during the bore.

“Basically, you can twist the hose a quarter of a turn without disconnecting it from the tool or the oiler,” Alexander says. “After turning the air off, you twist it a quarter turn. That allows you to engage it in either forward or reverse. In addition to ease of use, it allows you to get more compression, so the blunt force is greater at the head of the tool.”

Applications include the installation of sewer, water, gas, electric, fiber, irrigation and cable lines, especially for distances of 50 feet or less in urban areas where launch space is limited.

“An option we offer is the Mole Track system for all of the replaceable head tools,” he says. “It allows you to track depth and location so you always know where it is if you’re close to other utilities.”

The tool also features the Debris Free Tailcone that prevents debris from entering the piercing body for increased production and tool life. Wear rings eliminate metal-to-metal contact for decreased wear and greater sustained level of performance.

Alexander says as budgets become tighter, the piercing tool provides an economical alternative to directional drilling and can be viewed as a complement, depending on the application.

“Where you have a short shot or you’re replacing a two-lane road, piercing tools are a more cost-effective way of doing that,” he says. “When you’re replacing 300 to 400 feet of service, a directional drill is a more appropriate application. It’s getting the right tool for the job.”
