Hinge screws go in crooked when the pilot hole is off by a fraction of a millimetre. A self-centering bit fixes that by letting the hinge itself position the drill.
The pair in the photo are chrome, each with a hex shank, a knurled depth ring and a 9/64 inch mark on the barrel. The sleeve slides back as you drill and the point stays aligned with the hole in the hardware.
Hex shanks click into a quick-change chuck on a cordless driver, so you can drill and drive with the same tool. A depth ring then stops the cut before it pokes through a thin door skin.
Two bits in a pack let you keep one on the drill and one in the toolbox. At this size the pack is a small add-on to a bigger order, which helps clear the free-shipping threshold.
