Imagine being able to power carve anywhere! The New Thumb Micro Motor will allow you to do just that. The battery powered micromotor has variable speed from 3,000 to 30,000 rpm and is incredibly quiet and smooth. The battery takes between 2-3 hours to charge but you get between 5 and 7 hours of carving time out of a single charge. You can also use the Thumb while the battery pack is charging. The Thumb handpiece has plenty of torque to roughout a project and can spin fast enough to do fine detail. The handpiece comes with a 1/8" collet. You can also purchase an 1/8" to 3/32" and a 1/8" to 1/16" reducer (sold separately) so you can also use additional sizes of burrs with the Thumb. Kit includes: Thumb Quick Release Handpiece, Pocket Control Box, A/C Charger, and Handpiece Stand (packaging may vary).
