Abstract
A coolant and lubricant is supplied to the cutter head through the shank of a reamer. For this purpose an axial channel extends through the reamer shank and encloses in its front part a conical screw used for adjusting the cutter head and whose threaded shank has at least one longitudinal slot, so that the coolant and lubricant passes through the threaded shank into a ring channel in the front region of the reamer. The coolant and lubricant flows from said ring channel via outlet channels between the cutters. The outlet channels slope outwards in the direction of the leading edge of the cutters, so that an optimum cooling and lubrication of the latter is obtained.
