Universal Compatibility Description

This bilateral self-stop carbon brush set fits all wood & metal cutting power tools whose motor brush slot matches 6×14×17mm internal dimension.

Self-Stop Working Principle

Two safety limiting contacts are installed on both sides of each carbon brush. When graphite wears down to the threshold position, the circuit disconnects automatically, avoiding direct friction between copper wire and motor rotor to extend motor service life.

Installation Operation Steps

1. Completely disconnect power before opening motor housing cover.
2. Take out worn old brushes and clean internal carbon dust.
3. Install new bilateral self-stop brushes without squeezing copper wire.
4. Reassemble shell and test cutting machine normal operation.
