Quickly remove flat spots, high bars, grooves, ridges, high mica, and other commutator and slip ring defects. Regular maintenance of commutators and slip rings with Martindale Commstones is so easy it enables you to eliminate the above defects in their early stages. With Commstones, it is not necessary to take a machine out of service to resurface its commutator, thus production time is saved and time-consuming major overhauls can be prevented.
