Hammers
The CRI hammer series uses a uniquely engineered air cycle to improve hammer performance and durability, even with water injection. The valve-less design features specially configured porting to allow efficient water injection through the hammer cycle. That means a more durable hammer that drills fast wet or dry.
We also offer Hammer Parts and Repair/Reconditioning.
