ABSTRACT:
The disclosed cutting-tool comprises a stepped-diameter arbor with bearings supporting rotatably thereon a holder carrying the cup-shaped cutting bit. In accordance with the invention, the holder is made up of a hollow shaft and a sleeve encompassing this shaft. The sleeve is journalled adjacent to the cutting bit in one of the bearings located about the stepped-diameter arbor, said arbor having a central bore. The other bearing is accommodated within the central-bore and supports the hollow shaft likewise accommodated in the central bore of the arbor. Owing to the disclosed structure of the holder and its interconnection with the stepped-diameter arbor, sufficient rigidity of the cutting-tool, matched by its compact size is ensured.
