Pneumatic Crankshaft Polisher.
This air-operated crankshaft polisher features a high-torque output air motor that is designed to handle the toughest jobs in your shop. And because this polisher is air-operated, you won't have to worry about purchasing a replacement motor due to abrasive dust build up on the armature and brushes, a common problem with electrical units. Also cheaper to operate and safer to use than electrical units. Uses abrasive belts from 3/4" to 1-1/4" wide and lengths from 64" to 72".
