Reaming tools \ Technical introduction – reaming

The basics of reaming

reaming is part of the precision machining process or fi nishing process. holes are mainly reamed in case of
special requirements around surface quality, roundness, cylindricity and diameter tolerance.
set the hole with a particular allowance, see allowance table, then create the desired fi t with the reamer.

Note: if not necessary, do not countersink hole due to the negative impact on the service life of the reamer.
