The Mini Buffs feature all cotton construction & are used in tight radius areas often found in intake manifolds, motorcycle side cases, etc. Usually used with White Rouge (13001) or Tripoli (13135) but can also be used with other compounds. Use the Mini Buff on your drill or die grinder with either the 1/8" shank mandrel (13063) or the 1/4" shank mandrel (13054). We recommend the use o a dust mask like our Buff Shop Dust Mask (13000), Goggles (43090) and Gloves (31010) to protect from the dust & heat of buffing.
