Abstract
The invention relates to a reamer for machining through-holes, having a base body comprising a clamping region as well as a front-facing machining region with cutting elements, wherein the machining region comprises front-facing chip chambers and regions that are relief-ground on a circular cylindrical lateral surface defining the maximum radial dimension of the reamer in the machining region, which relief-ground regions are spaced apart from the perforated wall in a circular cylindrical through-hole, wherein the chip chambers and adjacent relief-ground regions are separated from one another by lateral surface portions.
