A brush is a critical current-carrying contact inside the electric motor, pressing against the rotating commutator to transfer electrical power to the armature windings. In floor grinders like the PG450 and HTC450, consistent brush contact is essential for maintaining full motor torque across heavy grinding loads. As the brush wears down over time, contact becomes inconsistent — leading to arcing, reduced power output, excessive heat, and ultimately motor damage if the worn component is not replaced promptly.
