This optional and shorter 45-3/4" long inner square drive shaft is non-conductive and different from our standard inner square drive shaft that comes on Series SRH, TXH and LXH motors. It was developed by our engineers for equine dentists and other users with similar applications. The S-10805-NC has a plastic motor connector in place of our standard metal components. This shaft can be used to replace broken or worn shafts on these motors:
M.SRH, M.SRMH, M.SRBH 
M.TXH, M.TXMH, M.TXBH
M.LXH, M.LXMH M.LXBH
Use with outer sheath S-10802-NC sold separately.
Replacement shafts require a VERY light coating of Foredom grease before use. Be sure to unplug your motor before doing any maintenance and never operate your Foredom without the outer sheath attached. We suggest that you view our maintenance videos featured on our homepage before installing this item.
