Claims12
A cutting tool comprising:
- a support having a cylindrical outer surface;
- a series of cavities spaced over said surface in at least one helicoidal row;
- a tool-carrier in each of said cavities, said tool-carrier including, in the upper part thereof and near the outer surface of said support, a cutter;
- a chip-breaker in each of said cavities, said chip-breaker including, in the upper part thereof and near the outer surface of said support, a blade arranged near the cutter in said tool-carrier;
- means for adjusting the position of the cutter in the tool-carrier in said cavity;
- means for adjusting the position of the chip-breaker blade in relation to the tool-carrier cutter;
- and retention means for securing the tool-carrier and the chip-breaker in said cavity, said retention means extending laterally from said cavity, through said support, and being accessible at said outer surface for said securing.
