<p>The tool consists of a carrier body (1) and a cutting body (2). The cutting body has expansion gaps (2a) parallel to the tool axis (Z), so formed that webs (2b) of material remain in them. The cutting body forms part of a unit, made in one with the carrier body. In operation, the expansion gaps in the cutting body act as individually functioning units, there may be at least two webs along a measured length of the cutting body parallel to the tool axis. The thickness of the web, measured perpendicular to the tool axis, should be 0.1-0.5 of the thickness of the cutting body measured perpendicular to the tool axis.</p> |
