Review on 🔩 Amana 55102 Drill Countersink for Furniture by Vincent Burton

If you're building cabinets or bookcases out of melamine board, Rockler's Firmit screws are great, and this fastener makes them easy to drill and install. This bit is for 5mm screws. (There is a similar drill if you are using the larger, longer 7mm screws.) This drill will drill two different diameter holes needed to prevent the panel from splitting, then countersink the head of the screw like desired.
