Backing Pads

PTA Spiral Cool packing pads for resin fibre discs have heavy duty rubber construction and a spiral design for superior cooling, resulting in longer disc life.

For an economical alternative, try our new polypropylene backing pads. These pads are lighter than the rubber alternative and can be used at higher RPMs.

All backing pads come complete with 5/8-11 centre nut.
