This air-filled sanding drum has extraordinary features that set it apart from any other sander.
The flexible rubber drum contains an inflatable air chamber which conforms to the work surface and disperses the heat away from the sandpaper. Air circulation inside the drum maintains the sleeve surface at an ideal temperature without overheating.
The result is perfect contact between the sandpaper sleeve and the work surface, with no heat build-up or gummy residue left permanently in the sandpaper.
Even when sanding against the grain, Sand Boss eliminates burn marks on hard or soft wood surfaces. Because the abrasive never overheats, sandpaper life is prolonged tremendously and the sleeve surface can be easily restored with a rubber cleaning block.
Inflate with bicycle pump or air compressor to firmness while not exceeding the PSI recommended on the tool itself.
