Brush Seater, 8 in X 3 in X 2 in, Grade Mh, Martindale Electric, Mfr#: BRSRX20MH

Our Brush Seaters come in 5 grades: ES EX tra Soft, FH Fine Hard, MS Medium Soft-our most popular, FS Fine Soft, and MH Medium Hard. Brush Seaters are used to easily and accurately seat commutator and slip ring brushes of any material. To use the Brush Seater, hold close to the brush so that Brush Seater material will be carried under the brush. At the same time, press on the brush to increase pressure. For best results, use a stone with a width equal to or greater than the width of the brush. For cleaning commutator pick a stone about 3/4 the length of the commutator bar and as thick as will neatly fit between the brushing rigs.
