    摘要： According to the invention, a drilling tool includes: a driving source; a transmission drive unit for transmitting a rotation force of the driving source; and a dust collector for collecting dust produced from a workpiece drilled by the end tool and blowing air against the workpiece, wherein a filtering means for filtering the air mixed with the collected dust and a centrifugal fan for taking in the filtered air and sending out the filtered air in a circumferential direction are provided, the centrifugal fan is disposed in a housing formed with an airflow sending port for sending a part of the air taken in to the dust collector and a discharge port for discharging a rest of the air to an outside, and a distance from the airflow sending port to the discharge port in a forward direction in a direction of rotation of the centrifugal fan is longer than the distance from the airflow sending port to the discharge port.

    摘要： An air chamber is formed in a cylinder between a piston and a striking member. The cylinder is formed with at least one through-hole for providing fluid communication between the air chamber and an outside of the cylinder. A switching mechanism switches operation modes between a first operation mode and a second operation mode. In the first operation mode, the at least one through-hole is closed when the working tool is moved toward the another end and, when the at least one through-hole is closed, reciprocating motion of the piston generates pressure changes in the air chamber, allowing the striking member to transmit a striking force to a working tool. In the second operation mode, the at least one through-hole is constantly open, prohibiting the striking member from transmitting a striking force to the working tool.

    摘要： A switching mechanism switches on and off transmission of a striking force to a working tool, and switches on and off transmission of a rotational force to the working tool, thereby switching operation modes among at least a rotation and strike mode, a strike only mode, and a neutral mode. A rotation locking mechanism engages a cylinder during the strike only mode, thereby locking rotation of the cylinder. During the neutral mode, the transmission of the striking force, the transmission of the rotational force, and the locking of rotation of the cylinder are all turned off.
