A down-the-hole hammer includes a barrel having a longitudinal axis and defining a middle chamber and a bottom chamber, a piston defining a top chamber and slidable within the barrel between the middle chamber and the bottom chamber, a control tube having a distal port, and an air distributor having a first distal port and a second distal port. The control tube is indexable between a plurality of rotational positions to adjust which of the first distal port and the second distal port of the air distributor is aligned with the distal port of the control tube.

A dust cover for a hammer work tool, a hammer work tool, and a method of attaching the same are disclosed. The hammer work tool includes a housing, a power cell enclosed inside the housing, a tool member, and a detachable dust cover. When attached, the dust cover prevents particulate matter from entering the housing. When detached, a housing opening uncovered by the dust cover provides access to the power cell for maintenance and repairs. During installation, a housing rim and a locking tab of the hammer work tool are respectively received by a groove and a locking tab receiver of the dust cover. Advantageously, the dust cover is durable, cost effective, and easily attached and detached without the use of additional tools.

A dust suppression system for a demolition hammer is disclosed. The dust suppression system may have a water hose routed within a power cell of the demolition hammer, and a connector channel internal of the walls of a front head of the demolition hammer. The water hose may be utilized to deliver water from outside of the demolition hammer to a connection valve on a top end of the front head, and the internal connector channel may deliver water from the connection valve to one or more nozzles located at a bottom end of the front head.

A flushing system in a drill bit, which has a body that defines the flushing system, can include an inlet to facilitate supply of pressurized fluids into a bore hole. A cutting surface of the drill bit is provided with a main opening that defines a main passageway in communication with the inlet. A peripheral surface of the drill bit is provided with a secondary opening that defines a secondary passageway in communication with the inlet. The secondary passageway is disposed at an angle from a horizontal reference plane. The horizontal reference plane is defined between the inlet and the origin of the main passageway and is perpendicular to a central longitudinal axis of the body of the drill bit. An origin of the secondary passageway is at a distance from the origin of the main passageway.
