Please observe that all button bits are manufactured over-sized 0,5–1,0 mm, meaning that for example a 36,0 mm bit is at least 36,5 mm as new.This is done because of the fast initial wear on button bits.
It is important to consider that the drilled hole could vary in size due to drilling conditions, drilling practices and ground formation.
