ABSTRACT:
A pneumatic tool comprises a motor element including a body in which a pneumatic motor is housed. The body is connected at one end to a compressed air supply hose together with a device for controlling the entry of compressed air into the motor. At the other end is a head provided with a bayonet coupling and a tool-holder having a tubular member guiding a shaft coupled to the motor. The tool-holder is provided at one end with a complementary bayonet coupling and at the other end with an angular part provided with a member adapted to support a tool. This member is coupled by a kinematic coupling to the shaft. The tubular member guiding the shaft is mounted to pivot relative to the shaft on the complementary bayonet coupling. The tubular member can be locked in any appropriate angular position.
