SuperNova2 Cole Jaws are large, flat aluminum plates. Rubber bumpers serve as padded jaws for positive, non-marring holding of nearly finished turnings. They hold objects too large for any other chuck, and they're especially useful for reverse chucking bowls. Each set comes with 8 rubber bumpers sufficient for almost any need. Mini Cole Jaws are designed especially to work on mini lathes with swing as little as 10".

External Gripping Capacity: 10"
