I like that the drill bits are straight, not tapered. The tip does not burn like other tapered drill bits I have tried. I like that there are extra drill bits included. I like that the counter sink is sharp and is in contact with the drill bit no matter what you adjust the depth at. The other tapered drill bits have more cutting edges for the countersink part, but when you adjust for a shallow hole, the countersink surface does not make contact with the drill bit, causing a bunch up of wood chip...
