Features

Clamped rear anvil

The 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 is the most secure assembly on the market.

Striker wear rings

The one-piece striker contains a set of wear rings that eliminate metal-to-metal contact, providing a sustaining level of performance.

Pushing collets

HammerHead ramming tools are set into taper-locking collets, decreasing set-up and tear-down time. The collets offer a full 6″ (152 mm) of engagement to the steel casing resulting in a secure locking of the tool nose to the casing, eliminating the need for a support cradle and reducing casing flare which helps save time on the job.

Collet lifters

On larger sizes of collets, Hammerhead offers collet lifters to conveniently move, load and unload heavy collets on-site.

Accessories

HammerHead offers a wide variety of pipe-ramming accessories, like lubricating systems, seal kits, balanced collet lifters, pipe pigs and ram collars. All designed to make your next job more efficient.
