Mounted on sturdy steel shanks, these felt buffing bob assortments really get into the tight spots. Great for putting the final touches on inticate 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 (#13028 and #13005). The small 1/8" shank sets are ideal for trim and the 1/4" shank set is great for engine component buffing. Max. 15,000 rpm.
