Hand-held grinding machine has coupling device which is partially surrounded by annular or ring-shaped extraction channel portion of suction apparatus to couple transmission shaft with tool receiver

摘要

The machine (100) has a drive motor (104) that is arranged at a proximal end (114) of a tubular rod (110) of a holder unit (102) while a tool head (108) is arranged at a distal end (116). A transmission shaft is connected with motor to transmit torque with a tool receiver (132) of tool head, and partially extended within tubular rod. A suction apparatus (170) is provided with an extraction channel (172) having annular or ring-shaped extraction channel portion. A coupling device is partially surrounded by channel portion to couple transmission shaft with tool receiver.
