Abstract

A dust suction device for detachable attachment to a hand-held drilling machine includes a housing, a telescoping suction pipe coupled to the housing, an electric motor positioned in the housing, a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, a dust collection container coupled to the housing and positioned upstream of the suction fan, and a support frame. The support frame includes a first portion coupled to the housing, a second portion coupled to a neck of the drilling machine, and an auxiliary handle extending from one of the first and second portions of the support frame. The support frame supports the drilling machine in a side-by-side relationship with the dust suction device.
