bristle brushes are usually made for a flex shaft. they are very
small circular brushes for polishing in really small places )or on
small pieces that would be too damaging on the buffer) I find that
they are good to get into hard to reach areas or one little spot that
needs a little further polishing. they (like buffs) come in
different textures (hard, medium and soft ) for a variety of uses!
(I always keep some on hand for a variety of reasons!)
