I used this drill bit to drill and countersink many of the screws in custom kitchen cabinets. You can tell right away that this is an excellent beat. The workmanship is perfect and the quality is very high. The tapered bit makes a big difference β it allows you to get the strongest "biteβ out of the screw while making screw insertion easier than with a non-tapered bit. You can also easily adjust the depth of the drill. It's perfect for what it was designed for. I would unreservedly recommend it.
