Spiralcool  7″ Rubber Backing Pad: 7 1/16″ dia., 5/8-11 threaded hub.
Made in U.S.A.

Custom Tire Cutting starts with a 8″ Spiralcool rubber backing pad, then we machine the pad to 7 1/16″ dia. so the pad will properly fit our 7″ sanding disc.

(Retaining nut and spanner wrench does not come with 7″ rubber backing pad.  They must be ordered separately.)
