ABSTRACT:
A single-blade reamer is guided in a hole by means of at least one guide fillet. The guide fillet is provided with a coating of cubical boron nitride (CBN) in the region of its guide surface facing the wall of the hole. The guide fillet thus withstands heavier loads, so that the reamer is suitable in particular for the economical machining of hardened steel alloys.
