Active Head piercing tools are available in 2” (50 mm), 2 1/2” (65 mm) 3” (75 mm) and 3.5" (89 mm) models.
The specially designed head / body retaining system and replaceable wear rings on the bit shaft and head promote longer life and sustained performance levels.

Original Clamped Rear Anvil
Don't settle for imitations. This original and field tested design provides for fast and easy field maintenance, the hallmark of the entire HammerHead Mole piercing tool line. Provides 200% more clamp load and is the most secure and proven assembly available.
Striker Wear Rings
Wear rings eliminate metal to metal contact decreasing wear and offering a sustained level of performance. Made of a specially designed composite, these rings offer a very low coefficient of friction and have a higher abrasion resistance compared to Teflon® rings used in competitive tools.
Patented Debris Free Tailcone
Designed to eliminate the introduction of debris into the tool body, increasing overall production and tool life.
Patented Power Port® Reverse
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 if a bore collapse occurs.
Optional Screw Reverse
This option offers flexible control of the tool and has a neutral position for easy locating.
