Commutators and slip ring brushes of any material can be easily and accurately seated with Diamond D Brush Seaters.

Features:

• Just hold the Brush Seater on the commutator close to the brush so the Brush Seater material will be carried under the brush
• At the same time, press on the brush to increase pressure
• Many commutator and slip ring troubles are caused by poor contact with the brushes
• These stones help prevent pitting of the brush faces, loosening of brush shunts, and burning of brush holders
