Abstract

A machine, e.g. a drilling or milling machine having a rotatable tool (6) feedable into the work, is provided with hold-down means (11) movable into clamping engagement with the top of a workpiece or stack of work-pieces and formed with an aperture (16) for the passage of the tool. The hold-down means may be a tubular element 11 co-axially surrounding a drill spindle 1 and formed with a piston 19 for movement under fluid pressure axially of the spindle to engage and clamp a work- piece stack 9 whilst the spindle with a drill 6 is fed into the work through a replaceable bush 16 of the tubular element. <IMAGE>
