Brush Seaters: These stones are used to contour carbon brushes to the shape of the commutator. This reduces sparking and increases motor efficiency. For brush seating, select a stone that has a width equal to or slightly larger than the brushes that are to be seated. For commutator cleaning, select a stone that is about 3/4 the width of the commutator bar and a thickness that easily fits between the brush riggings. For slip rings, select a stone that is about 1/2" wider than the ring.

Grades & Applications :

ES: Extra Soft - For slip rings - Sizes bigger than 0.500 x 1.000"
FH: Fine Hard - Small motors: Vacuum cleaners, fan motors, automibile generators, etc.
MS: Medium Soft - General purpose large motors - Sizes bigger than 0.250 x 0.750"
MH: Medium Hard - Similar application as MS grade but slightly harder
