Abstract: A selectively attachable dust suppressing misting device for use with percussive tools, such as air hammers or jack hammers, includes a frame having a first tube section connected to a fluid source. The misting device includes one or more misting nozzles connected to the first tube section to allow fluid to flow out of the misting device. The misting nozzles are rotatable to allow fluid to be sprayed in a desired direction. The device also includes at least one adjustable clamp for securing the device to various diameters of percussive tools. Preferably, a second clamp is mounted to a housing slidable on the first tube section to allow the second clamp to be moved with respect to the first clamp.
