Hand sanding is tough labor, something that most woodworking and woodturning projects require, but everyone seeks to avoid. New Wave Scuff & Buff Balls are a great alternative. The patented wavy edge design insures consistent finishing quality, and the continuous exposure of new grit means the uniformity of the Scuff Ball does not change. The material allows highly efficient airflow, resists clogging, and leaves the Scuff Ball easy to clean by water or compressed air.
