Metal disc used to clean the internal Buffer pad wheel. Use after every 15 repairs. Fits the VMI 3550 Buffer model only. The buffing wheel fills up with dust and dirt as it operates and this can cause shortening of life. To rectify this we recommend the use of this cleaner disc regularly (after every 15 repairs).
