JoolTool - N-3001 Ninja See-Thru Backpad, 3" Diameter (Pack of 1)

At the core of our innovative sharpening system are our PATENTED NINJA SEE-THRU discs, often referred to as “Backpads”. The combination of straight and curved slots within the disk allow the operator to sharpen, grind or polish with a crisp & clear view of the work piece. Simply hold the object from the bottom of the disk and apply very light pressure, the JOOLTOOL does the rest. The disk consists of 2 faces, each with a particular function. The top has a molded fin structure that directs airflow onto the workpiece, keeping it cool. The bottom is a perfectly trued, flat surface onto which our 3M NINJA ABRASIVES adhere. The backpads are easily mounted onto the JOOLTOOL system by simply twisting on and off the spindle; they are self-threading and do not require any mounting hardware. For best performance, mount each abrasive on its own Backpad
