DTH Hammers

The CRI hammer series uses a uniquely engineered air cycle to improve hammer performance and durability, even with water injection. The valveless 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.

A valveless air cycle provides consistent drilling performance and reliability foot after foot and year after year.
