For best results cut the wood a bit oversize and sand along template with a steady even pressure. Caution: Maximum safe speed is 2500 rpm. Do not use in router or shaper. Do not touch while spinning. Built-in template guide. A pilot bearing rolls along the workpiece and will not allow you to oversand. 3/8" shank size
