SINCE 1848

The combination system

The design of this system is based on BRAUN wall saw tracks.
The BBZ2 is the two-column version of the modular system for large bores. Furthermore, vertical wall saw cuts can also be performed. An assembly without dowels is possible, as the frame can be supported against the ceiling. Due to the extension possibilities of the modular system, a multitude of drilling tasks can be covered with the BBZ2.
Various feed drives, from manual to hydraulic, are available for this combination system. Drill bits up to a diameter of 1000 mm can be used with the BBZ2.
Set consisting of:
2x base plate for doweling
1x connector
1x connecting plate
2x support
* trapezoidal thread design upon request
