A device for sucking up material removed by the bit of a portable drill is made in the form of a casing provided with means for securing it to the drill and having at least one portion constituting a handle to enable it to be gripped in one hand by the operator. The device comprises a suction head fitted slidingly on the casing to enable it to be kept close to the point of penetration into the surface of a body to be drilled by the bit fitted on the drill. Disposed inside the casing of the device are a fan with intake connected to said head through a connecting duct and with outlet blowing into a container, supported by the casing, for collecting the aspirated material, an electric motor to actuate the fan, electric batteries to supply power to the motor through an operating switch. The casing of the drill alternatively comprises an electric socket designed to receive a corresponding plug mounted on the vacuum device so as to supply power to the fan motor by taking it from the power supply of the drill.

Abstract

A device for sucking up material removed by the bit of a portable drill is made in the form of a casing provided with means for securing it to the drill and having at least one portion constituting a handle to enable it to be gripped in one hand by the operator. The device comprises a suction head fitted slidingly on the casing to enable it to be kept close to the point of penetration into the surface of a body to be drilled by the bit fitted on the drill. Disposed inside the casing of the device are a fan with intake connected to said head through a connecting duct and with outlet blowing into a container, supported by the casing, for collecting the aspirated material, an electric motor to actuate the fan, electric batteries to supply power to the motor through an operating switch. The casing of the drill alternatively comprises an electric socket designed to receive a corresponding plug mounted on the vacuum device so as to supply power to the fan motor by taking it from the power supply of the drill.
