Abstract: Lustering plate (1) formed from a foam body (2), endowed with a securing surface (21) to be secured to the rotary plate of a lustering machine and having an active surface (22) wetted with the lustering liquid and coming into contact with the surface to be lustered. The lustering plate (1) incorporates a reservoir of lustering liquid (3) incorporated into the foam body (2). The reservoir (3) has a dispensing valve (4) in the axial position dispensing onto the active surface (22). The valve (4) has a valve seat (41) closed by a blocking device (43) returned to the closed position and endowed with a control device (44) opening the valve (4) by impelled pressing of the foam body (2) via its active surface (22) against the surface to be lustered.

Abstract: Auxiliary handle installed on the casing (11) of a drill (1) having a drilling axis (Xo), incorporating an electronic acceleration meter (231), with axes (XoYoZo) defining a reference point; one (Xo) of the axes being the drilling axis; the other axis (Yo) being that of the handle (2); and a reference surface (SR, SR1-SR3, 3, 4) associated with the reference point of the acceleration meter (231) to register the relative position between the surface to be drilled (S) and the drill (1), and calculate the set position of the drilling axis (Xo), and a display (25) to show the set position of the handle (2) calculated from the set position of the drilling axis (Xo) to execute the drilling.
