This is a handy tool combining a 4.2 mm drill with a M5 x 0.8 tap. It has a standard 1/4" hex shank, and works very well in a cordless drill. It can be used to drill and tap holes in materials up to 6 mm thick (aluminium plate, plastic sheet, mild steel), in a single operation. It can also be used to tap MakerSlide and other aluminium profiles, although not very deeply (our spiral taps are better for that).
Please note that this tap does not fit into a tap handle, because it has a hex shank, not a square like normal taps.
