The set includes tapered countersink drill bits (#4, #6, #8, #10, #12) that produce an 82° finish, plus self-centering drill bits (#6, #8, #10) for positioning holes for hinges and other hardware. When you need repeatable depth, the included depth stop rings help you stay consistent across multiple holes.
With 1/4″ hex shanks, these bits are made to fit common impact drivers and drills, and the magnetic extension bit holder helps with reach and quick bit changes. Everything stores neatly in the included case for grab-and-go convenience.
