These 3" diameter Buffing Balls are made from non-woven material and impregnated with abrasive. They are great for working inside and outside of bowls and are available in four grits: 180 (Green), 320 (Maroon), 600 (Grey) and White (Non-Abrasive). The White is used for polishing to a gloss sheen and applying wax. The shaft is held in a 1/4" or larger drill chuck.
Each buff is made up of 10 wavy edged layers of non-woven material held together on a 3-1/2" shaft. Overall length is 5". When worn from use, the buff material can be flipped over to double the life and when worn out, replaced with new material.
