QL DTH hammers are used in drilling applications to produce holes in rock and other materials. They work by using a high-pressure air supply to drive a piston that delivers a hammer blow to the drill bit, creating a hole in the material. QL DTH hammers are typically used in industries such as mining, construction, and water well drilling. They are designed to be durable and efficient, and they can be used with a variety of drill bits to suit different drilling applications.
