Mounted on sturdy steel shanks, these felt buffing bob assortments really get into the tight spots. Great for putting the final touches on intricate pieces where larger buffs simply will not reach. All are made of long-lasting hard felt and will work well with any of the buffing compounds. Great for cleaning out residue left from buffing. A perfect accessory for the Foredom Craft Kit. The smaller 1/8in. shank sets are ideal for trim pieces and the 1/4in. shank set is great for engine component buffing. Max 15,000 rpm.
