In many cases spot-facing operations present considerable difficulties, it is most useful therefore to have available versatile and efficient tools which carry out such operations in an easy and speedy manner. With this in mind Polledri have introduced in the back-spotfacing cutters of Groups 30 and 40 a very important innovation, that is a Rolling Pilot which is fitted to the tool and permits also forward spotfacing operations, consequently the cutter and arbor can be used for operations in back-spotfacing and can also be used for forward spotfacing operations.
