Our boring heads are designed with insert pockets and cartridges that are integral with the body of the head to provide maximum rigidity and accuracy. Two offset center lock screws apply maximum tightening force between the boring head and the toolholder. PinzBOHR is a flexible boring system for holes ranging from 0.315″ up to 19.685″. The system includes all necessary extensions and reducers, rough heads, finish heads and even includes face mill arbors and end mill holder options.
