HammerHead Active Head^® Mole piercing tools are specially designed to perform in adverse ground conditions. The reciprocating head design features a double-strike system that utilizes the initial impact force to increase production in difficult soils such as cobble, hard clay and hardpan. Active Head piercing tools are available in 2” (50 mm), 2 1/2” (65 mm) and 3” (75 mm) models.

Replaceable Head
The specially designed head / body retaining system and replaceable wear rings on the bit shaft and head promote longer life and sustained performance levels.

Heavier Striker and Wear Rings
HammerHead uses a much heavier striker than competitive models, that provides overall increased impact force and production. The one-piece striker contains a set of wear rings that eliminates metal-to-metal contact, providing a sustaining level of performance.

Power Port^®
This patented quarter-turn reverse feature pneumatically locks the tool into forward or reverse gear, preventing accidental direction change during the bore. The valve whip is designed to be flexible, preventing tool binding if a bore collapse occurs.

Clamped Rear Anvil
The patented rear anvil is a hallmark of the HammerHead piercing tool design. This feature provides up to 200 percent more clamp load than competitive models and offers fast and easy field maintenance capable of being performed on the tailgate of your truck.
