Sanding MDF Recommendations
 

For sanding lineal MDF moldings successfully with Bardo Flex Sanding wheels, you will need a sanding setup that consists of board being powerfed underneath a rotating sanding wheel(s) that is(are) lowered onto the board surface. Our customers have enjoyed success using the following Bardo Flex Sanding wheels:

#2 Top Head
* Bardo Flex Woodworking 8 x ? x 3 Sic 280 KW W105 Trt (this is a very dense wheel which makes shaping it harder than the other wheels. Designed for raw MDF sanding)

Bardo Flex Impregnated Flap 8 x 1 x 3 Alox VFN MD C-6 Trt
#2 Side Head

The 280 grit KW wheels also work well for side heads. We would recommend using or testing (1) KW wheel on one side head and (1) Alox VFN C-6 treated wheel on the other side head and compare finishes.
