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.
Device for machining an outer side, coaxial to a geometric longitudinal axis, of a workpiece, comprising a cutting head which can be fitted axially over the outer side of the workpiece, a cutter plate which can be attached to the cutting head and whose cutting edge extends parallel to and at a first predeterminable radial distance from the geometrical longitudinal axis, and comprising at least one guide surface which is arranged on the cutting head and which can be slidingly applied against a portion of the outer side of the workpiece, characterized in that the guide surface (48) is formed on a guide strip (45), further comprising means to detachably attach the guide strip to the cutting head (11).
