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.
When it is of importance, also consider that the hole is always 1,0–3,0 mm bigger than the bit dimension depending on rock formation
