Fixed and Slip Renewable Drill Bushes
These two features are incorporated on one bush, which is used in conjunction with liner bushes, and is held in place by a lock screw, tenon or stop pin. The bush is a slide fit in its corresponding liner.
The removable fixed feature of the bush is normally used in high production work, where the bush can be easily and quickly replaced with a minimum loss of production.
The removable slip feature of the bush is used when more than one operation is carried out; the bush is instantly removable after each operation.
