A nozzle is used to remove by means of suction dust and chips resulting from a drilling machine (13) in an industrial plant. The nozzle (20) has two opposite end portions (21, 22) communicating with one other: a first tubular portion (22) for connection to a suction tube (18), and a second tubular portion (21) with an intake opening (27). An outer flange (24) extends transversely from an intermediate position between the first tubular portion (22) and the second tubular portion (21). The intake opening (27) is directed in a lateral direction, parallel to the transverse direction of the flange (24). A magnetic element (25) is incorporated in the flange. The nozzle can be applied to a drilling template (10) having a plurality of cylindrical through-openings (11) in which respective bushings (12) made of ferromagnetic material are fixed. When the second tubular portion (21) is inserted through a cylindrical bushing (12), the magnetic element (25) acts on the bushing, opposing axial and rotational movements of the nozzle with respect to the template.
