Concerning bit diameters

Note that all bits are bigger on diameter than the given measurements in the catalogue. Cross bits:Can be max 1 mm larger due to manufacturing tolerances.

Button bits:Are max 3,0 mm larger for some designs in order to make up for fast initial wear on the diameter. The minimum diameter is 1,5 mm above given measurement.

Keep in mind that a bit always gives a bigger hole than the stated bit diameter.
