The benefit of a replaceable strip sanding brush is that the sanding strips are detachable from the hub, allowing worn sanding strips to easily be replaced without having to change the hub itself every time. This not only reduces replacement costs but is also environmentally friendly. Cosma produces a wide range of sanding brush strips that are suitable for many different systems. If required, the corresponding hubs can also be supplied. The advantage of fixed head brushes is that they can accommodate more sanding material and can be used at higher speeds (higher r.p.m.), thereby offering increased capacity and productivity. They are very quick to assemble and there is no investment in expensive hubs.
