<p>The tool (2) has a shell type construction main housing (4) from which a tool spindle (14) projects towards the working tool side end (18) and rotates around operational axis by a motor (12). A gear unit (16) accommodated in main housing transmits a driving torque from motor to the spindle using a ratchet percussion mechanism that has toothed rim fixed respect to housing, and is connected to supporting element which is formed in a circumferentially extending manner at an inner surface of the outer shell of the main housing.</p> |
