ABSTRACT:
An external reamer has a cutting head (11) having two claws (15, 16) projecting parallel to the axis from a base (12). On one claw (15) is fastened a cutter plate (28), whose axially parallel cutting edge (32) is directed radially inwards in order accordingly to machine a cylindrical outer side of a workpiece. On the other claw(16) a guide strip (45) is detachably fastened by means of at east one clamp screw (57), so that its guide surface (48) lies, diametrically opposite the cutting edge, against the outer side of the workpiece and stabilizes the machining operation. This guide strip (45) is preferably capable of fine adjustment in the radial direction by means of a pressure screw (63). The detachability of the guidestrip (45) has the advantage that the surface of the guide face (48) can be produced without problems separately from the cutting head (11) and with any desired shape. In the same way a plurality of similar guide strips distributed around the circumference may also be provided.
