See-Thru™ Backpads in 4”, which you need to use your abrasives on the JoolTool - ideally, get one for each abrasive you'll be using.
Combined with 3M abrasives, they allow you to sharpen, grind or polish with a crisp and clear view of the work piece.
The top of the backpad disc has a moulded fin-like structure which directs airflow onto the workpiece, keeping it cool. The underneath is a perfectly trued, flat surface onto which you attach your 3M See-Thru abrasives.
If you're using fine abrasive film you will get an even better result and your abrasives will last longer if you add a Bumpon cushion between your abrasive and the backpad.
To install on the JoolTool™ system, simply twist onto the spindle. NO mounting hardware needed!
Available as singles or pack of 3.
