The electronic speed control maintains constant speed under load, and a variable speed control dial allows the user to match the RPM to the application. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zigzag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation.

If the grinding wheel catches or binds, the coil spring relaxes and disengages the gears from the motor. As the grinding wheel stops, the gears and motor are protected.
