Key Features

High Performance

Automatic shut off offers blank firing protection by stopping the piston when there is no material under the tool to help extend the life of the hammer.

The internal buffering system helps reduce machine vibration and increase noise suppression.

The standard silencing feature allows you to use a Performance hammer on job sites in noise-sensitive areas like neighborhoods or near hospitals where noise is regulated.

Increase Productivity

Manually adjust the piston speed by choosing between high piston speed or maximum power to help increase efficiency and production on the job site.

The oil-fired operating cycle helps provide full power during every blow and less waste heat.

Critical hydraulic components are shielded from damage inside the housing, helping decrease downtime on the job site.

Easy to Maintain

Standard on-board autolube provides continuous greasing as the hammer runs, eliminating the need for manual greasing.

The slip-fit and 90-degree rotatable lower bushing allows for easy replacement in the field, helping reduce service time and extend service life.

The oil-fired design eliminates the need to check gas charge.

Quick and easy access to maintenance areas helps make hammer maintenance simple.

Boost Efficiency and Productivity with Integrated Technologies

Track your entire fleet of attachments and machines from one source. Hammers with asset tracking can be viewed within VisionLink®.
