What is the difference between a Flap Brush and a Combi-Wheel ?
A Flap Brush is a wheel made exclusively from non-woven heavy duty Valgro-Fynex material (flaps) and is used for finishing applications. As the name denotes, a Combi-Wheel is a combination of alternating flaps of Valgro-Fynex and Coated Abrasive material creating a “firmer” wheel that provides a higher rate of cut.
