Diamond Resin Bonded Flexwheel

This product consists of a hard plastic hub with a layer of foam between the hub and belt (made from industrial waterproof cloth backing) that was originally designed for the lapidary industry (gemstones) but has been found to be an excellent solution for aggressive grinding and fine polishing of thermal spray coatings such as HVOF, tungsten carbide and other hard materials. Our Flexwheel performs aggressively with a slight drape to eliminate scratching and flat spots.

Our Flexwheels are available in (2) sizes 1.5 x 6 & 2 x 8 Inch that includes a 1” telescopic bushing. Bushing is available for purchase at a cost of $1.40 each with a minimum order of $50.
