Multi-edged machining tool for post-machining of bores

Multi-edged machining tool for post-machining or precision machining of bores, for machining deep bores, a plurality of axially separated bores of the same dimensions and quality, or bores for accommodating bearing bushings for a camshaft, the tool comprising:

• at least one cutting edge set having a predefined nominal diameter and cutting edges distributed essentially uniformly over the circumference;
• and
• a guide body arrangement offset axially thereto, the guide body arrangement an integral component of an essentially cylindrical guide body which consists of solid carbide and forms at least n helical guide ribs which are at a uniform circumferential distance from each other, which extend through a centring or wrap angle which is greater than 360°/n, where n≧2, and to which a nominal diameter is assigned, the nominal diameter being essentially smaller by twice the size of a lubrication gap which forms during use of the tool than the nominal diameter of the cutting edge set which is adjacent in the feed direction.
