Dispositivo de furar para a produção de furos com corte traseiro

摘要

The drilling device has the drive motor (30) of a drilling shaft (34) able to turn on a ball joint (42) so that it can be diverted over an angled surface (74) and be driven in precession motion via a spindle transmission (48,58). The turning unit is connected to a drill bit receiver (36) and can turn about a pivot (41). Either the spindle (58) or its nut (48) can be pushed in the direction of the central longitudinal axis (16) of the drilling device (10). When pushed forward, the turning unit is diverted from the middle position by a diverting mechanism.
