Product details
This Commutator Cutter in hard brown is a professional shop tool sold as a 2-pack, each stick measuring 1/4 by 1/2 inch. It resurfaces the commutator on a vacuum motor's armature, cutting away carbon buildup and light scoring from the copper segments.
Over time, carbon from the motor brushes glazes and scores the commutator, which degrades brush contact and robs the motor of power. Dressing the surface with a cutting stick restores clean, even contact so the brushes seat properly and the motor runs at full efficiency, extending its service life.
- Function: abrasive stick for resurfacing motor commutators
- Quantity: 2-pack, 1/4 by 1/2 inch each
- Benefit: restores clean brush contact and full motor power
- Tip: the spare stick keeps a longer servicing session going
Use the cutter to dress the commutator during motor service, then clear the dust before reassembly. It is a shop staple for anyone rebuilding vacuum motors.
