UTENSILE COMBINATO PER FORARE E PER FRESARE |
摘要 |
A combined boring and milling tool has at least three triangularly shaped turnable cutter blades. The effective cutting edge of the first turnable cutter blade extends as bit (or drilling cutting edge) from the periphery of the shank at least to its axis. A second turnable cutter blade is offset 180 DEG peripherally from the first and its effective cutting edge extends as cutting edge on the periphery of the shank parallel to the shank axis. A third turnable cutter blade is offset axially from the first so that its effective cutting edge extends as a cutting edge parallel to the shank axis. The two effective cutting edges of the second and third turnable cutter blades lie on the same flight circle and their working ranges overlap axially. The first and third turnable cutter blades have a common chip space. |
