The innovative laser converted rolls feature the same Cyclonic spiral hole-design found on the Multi-Air Cyclonic disc range which optimizes dust extraction while reducing surface imperfections. Another benefit of the new hole-design is that it does not need to be lined up with the holes on the vacuum file boards or vacuum hand blocks to achieve optimal performance so changeover is fast and easy. In addition the rolls are perforated every 2-3/4" to allow it to be torn easily to fit multiple file board lengths.
