There are all different kinds of wood drill bits depending on the application. Here are some of the most common ones:
Brad point drill bit– A characteristic feature of brad point drill bits is their thin point in the middle of the tip, which is used for centring. Wood drill bits are usually made of a chrome vanadium alloy.
Auger bit– For drilling deep holes. The centring tip of the drill bit is additionally equipped with a fine auger thread. The wood chips can be removed well from the drilled hole by means of a large flute.
Forstner drill bit– For producing holes with large diameters, e.g. like those required for fitting hinges in furniture.
Nailbit– Gimlet with very thin tip for pre-drilling small holes for nails in wood.
