Abstract
The device drills large diameter openings in articles of high rigidity. It improves quality, raises productivity and facilitates the maintenance of the drilling machine. The device consists of a base (5), attached to the drilling machine's body. On the base (5), there is a reducing gear (7), whose outgoing shaft engages an eccentric wheel (8), embraced by a reciprocating yoke (9), jointly connected to a cantilever beam (10). The other terminal of the yoke (9) encompases a rotary roller (11), which - with a cradle (12) - is connected to a lever (13) for manual control over the drilling machine's spindle.<IMAGE>
