Spiralcool backing pads
Spiralcool's slotted hub draws cool air behind the disc. Spiral ribs provide contact points forming channels for air flow, extending disc life 30% to 50%. These backing pads are ruggedly built, lightweight, and stay in balance. Rigid type backing pads are used for straight flat work. Medium or flexible backing pads are used for contours. Other general recommendations: Rigid for 16-24 grit discs, Medium for 36-60 grit discs, and Flexible for 80-120 grit discs. Disc nuts are not included with these pads. Order center nut separately from the accessories listed below. Center nuts are available for different abrasive disc diameters.
