ISCAR Bore MB50 Quick Change Holder

The ISO30 shank is inserted into the spindle and held in place via the drawbar. Once the shank has been inserted into the spindle it remains there and and all tooling (end mill holders, collet holder, facing cutters, etc) can be inserted into the shank and secured by tightening one screw. The extreme accuracy and rigidity in milling and boring operations is maintained by the ITS cylindrical-conical coupling and radial-expanding pin. MB50 refers to the type of connection between the shank and toolholder. ***Only for mills with ISO30 spindle taper***
