This adapter allows you to use 2" and 3" roloc sanding pads on your proxxon mini grinder. These fine grit sanding pads are inexpensive and highly effective for sharpening bits. The heavier grit pads make this an amazing tool you will wonder how you ever got along without, for ice, wood, or metal.
This is a newer low profile than the earlier model which enables you to reach in tighter spaces when carving on ice, wood, or metal and better control when sharpening your bits. A refining dream tool.
