Vermeer Hole Hammer Pneumatic Piercing Tool

Hole Hammer pneumatic piercing tool features a moving-head design that provides full striking force of the piston to the head of the tool, pulverizing stones into the surrounding soil.

The residual energy generated is used to help the tool body travel through the compacted bore path. This results in more accuracy in tough soil conditions and reduced tool deflection, Vermeer says. The tool also incorporates a mechanical reset for the head assembly, helping ensure each blow delivered compacts soil in front of the tool to increase production and accuracy. The Vermeer Hole Hammer piercing tool is available in 2-, 2.5- and 3-inch sizes.
