The RBU reverse boring bars are available now and will be the new standard from May 1. In addition to the cutting edge position, the shank diameters, the shank design (partly with reinforcement collar) and the lengths have changed for some dimensions. The effective lengths, however, remain unchanged. For d=50, the insert has been replaced by a smaller insert. Otherwise, the previous inserts can still be used.
Also new is the internal coolant supply from diameter 18, so that now all tools except for d=15 ensure reliable cooling of the insert. Suitable inserts in various carbide, HSS and PCD designs can be found below or in the catalog.
