These wheels are normal flap wheels that have been impregnated with a special mixture of resins that weld the single flaps to each other.
This particular process allows for a more compact wheel, which increases efficiency and improves the tightness of the machined profile. The impregnation does not affect the general characteristics of the flap wheels, therefore they keep their properties of flexibility and elasticity.
The wheels are available in different densities to satisfy every working needs.

These wheels are used on all types of woods, MDF, veneers and various kind of paints.
The impregnated flap wheels are useful in many applications for buffing of UV and Acrylic (Water Base) paints when the thickness of paint is more consistent, and it's necessary to apply a more efficient and aggressive cutting.
