Grinders can have a brushed or brushless motor, and the primary difference lies in the mechanism through which the motor powers the tool. Brushed drills use carbon brushes to power the motor mechanically. On the other hand, brushless grinders do not have brushes and use an electronic circuit board with magnets to spin the rotor.
