Martindale, COMMX952ECM, 1-1/8" x 1/2" x 5/16" Extra Coarse 36 Grit / Medium 90 Grit Small Motor Combination Stone
Features:
- Handy two-grade stone is excellent for use on fractional horsepower motors.
Applications:
- Extra Coarse - 36 Grit: for use where a great deal of copper is to be removed and a very fast cutting stone is desired for pitted and grooved conditions.
- Medium - 90 Grit: for use where only high mica or a small amount of copper is to be removed.
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.
