💡 What triggers premature wear on carbon motor brushes in workshop sanders?

Regular friction against the commutator slowly erodes the graphite tips, especially when you push the tool hard through dense lumber. A handy rebuild using factory-spec parts stops voltage drops dead in their tracks and keeps the dust extraction pulling strong.

• Monitor the copper cord insulation for cracking after several months of heavy use
• Clean the commutator grooves thoroughly before seating new springs and holders
• Run a quick test cycle to confirm even spark reduction before reassembling
