Self-centering drill bits ensure that pilot holes are drilled straight and perfectly centered, so screws sit flush with the surface instead of at an angle.

The most common use for this type of drill bit is for installing hinges, door handles, drawer slides or wherever accurate pilot hole placement is crucial.

The drill bit has a spring-loaded metal sleeve covering it. This sleeve retracts and automatically centres the drill bit when pressure is applied.

Self-centering drill bits simplify the process of drilling pilot holes and eliminate the risk of off-centre holes.
