Combined flap wheels with hole represent a set of flaps made of Non-woven and grinding cloth.
   Due to this feature, they are more durable than Non-woven wheels and have a higher polishing capacity.
   After processing surfaces with a combined wheel there are no processing wastes (such as usedup abrasive seeds, fibers and slivers of the processed material). In some operations during polishing wood, marble, brass, tin, silver and leather parts, these wheels yield better results than Non-woven wheels.
   They are successfully used in manufacturing medical instrument in jewelry and art crafts.
