Abstract
Official abstract text for this publication.
A reamer has a shank made of steel and a cutting body made of a harder material, wherein the cutting body forms the outer circumference of the reamer in the region of the workpiece side end and has all the cutting ribs.
First claim
Opening claim text (preview).
1 . A reamer with a workpiece-side and a drive-side axial end, a shank made of steel for mounting in a drive shaft, and circumferentially spaced-apart cutting ribs, wherein a cutting body produced as a separate part and made of a harder material than the shank is provided, which cutting body forms the workpiece-side end of the reamer over the entire outer circumference of the workpiece-side end and which is fastened to the shank. 2 . The reamer as claimed in claim 1 , wherein the cutting body has integrally formed cutting ribs, wherein all the cutting ribs are formed only on the cutting body. 3 . The reamer as claimed in claim 2 , wherein chip grooves on the cutting body merge into chip groove run outs on the outer circumference of the shank. 4 . The reamer as claimed in claim 1 , wherein the shank has an end face which faces the cutting body and on which the cutting body is soldered. 5 . The reamer as claimed in claim 1 , wherein the cutting body forms the workpiece-side end face of the reamer. 6 . The reamer as claimed in claim 1 , further comprising at least one coolant passage extending from the shank to the workpiece-side end face of the reamer and preferably opens at the end face. 7 . The reamer as claimed in claim 1 , wherein the shank has a shoulder, with a larger-diameter section joining the cutting body and a smaller-diameter section to be mounted in the drive shaft. 8 . The reamer as claimed in claim 6 , wherein the at least one coolant passage emanates from an end face formed by the shoulder. 9 . The reamer as claimed in claim 1 , wherein the cutting body has the region with the largest outside diameter of the reamer and possesses a larger outside diameter than the shank. 10 . The reamer as claimed in claim 1 , wherein the cutting body is a sintered body made of cermet, or of carbide. 11 . The reamer as claimed in claim 1 , wherein the cutting body is soldered on the shank.
