The values given take into consideration the basic manufacturing tolerances as standard. These are Diameters up to Dc 6 mm 0.004 mm 0 more than Dc 6 mm 0.005 mm 0 The specified fits on the white background can be manufactured with 1/100 reamers, since they correspond to the manufacturing tolerances for reamers in accordance with DIN 1420. The lower tolerance field dimension for reamers in accordance with DIN 1420 has been reduced by 25 % for the fields with the green background. The result of this is that the usage period of the reamers is reduced in relation to the hole tolerance. The additional values in the green fields can be used in special cases.
