The small set contains six pieces - (O.D.) 2”, 3.5”, 5”, 6.5”, 8”, 9.5” and 11”.

Use these perfect circles to begin making rings for everything from kick panels and door speaker depth reducers to woofer rings for popular woofer sizes. Make the rings larger or smaller using our rabbet bit or oversize bearing sets to increase or decrease the size of the template you make to EXACTLY the size you need! If you wish, you can use only a section of the ring to create a large radius or half circle. With this new added range of sizes, you can create just about any circular based shape.
