Carbon Brushes 5x5x8 mm Dremel 300 395 595 3000 6000 – Carbon Brushes 90930

Is your Dremel or rotary tool running intermittently, losing power, sparking, or simply refusing to start? In the vast majority of cases, the motor brushes are worn. These 5x5x8 mm spring carbon brushes are sold in pairs, exactly as they are replaced, and can get a tool back in service for just a few euros instead of buying a new one.

Contents

Depending on the quantity chosen: 2, 4, 6, 8 or 10 5x5x8 mm spring carbon brushes.

Maintenance

Check the brushes every 50 to 100 hours of use. A brush worn to less than a third of its original length should be replaced. While the tool is disassembled, use dry compressed air to blow out the commutator and remove graphite residue.

Precautions

Always disconnect the tool before working on it. Always replace both brushes together, never just one: brushes with different wear levels cause imbalance and premature commutator wear. This is why they are sold in pairs.
