RMT CD22 is mostly used for light to medium clay digging, mining, and soft tunneling applications. It is also used in exterior wall renovations, breaking hard rock in tunnels or mines. Because of its slim design, it can be used in tight spaces. Despite its low weight, it provides very powerful blows at a relatively low frequency and it can be used vertically, horizontally, or overhead. This Clay Digger has an exhaust port at the top so the whole hammer can be buried almost to the handle. It comes with a screwcap retainer with a round chuck and a sound-reducing muffler.
