Carbon Brushes 316034830 for Metabo W14-125 Angle Grinders & KS66 (00542420) Circular Saw

These are carbon brush accessories with the part number 316034830, specifically designed for the Metabo W14-125 angle grinder and KS66 (00542420) circular saw. They serve as critical consumable components in the motor systems of these two power tools.

Key Information Breakdown:

1. Product Type: Carbon Brushes
   Made by pressing a mixture of high-purity graphite and copper powder, they conduct electrical current to the rotor windings through sliding contact with the motor commutator, driving the motor to rotate. Their self-lubricating properties reduce frictional wear and extend motor lifespan.

2. Compatible Tool Models:

• W14-125 Angle Grinder: A professional-grade 125mm Metabo angle grinder, suitable for heavy-duty tasks such as metal cutting and stone grinding, with a power rating of approximately 1400W.

• KS66 (00542420) Circular Saw: A Metabo 165mm lithium-ion circular saw, used for precise cutting of wood and profiles, belonging to the cordless tool series.

3. Technical Specifications:

• Dimensions: Typically 8×8.5×13.5mm (length × width × height), with details subject to the product manual.

• Current Capacity: Rated current ≥15A, meeting the demands of high-load tools.

• Service Life: Approximately 30–50 hours under normal operating conditions (depending on usage frequency and load intensity).

4. Replacement Indicators:

• When the brush length is worn down to less than 1/3 of its original length (about 5mm).

• When the motor produces abnormal sparking during operation (especially at the moment of power-off).

• When the tool shows significant loss of power or jamming.

Usage Recommendations:

• Replace both brushes simultaneously to ensure balanced conductivity.

• Clean the oxide layer on the commutator surface and use compressed air to remove residual carbon dust.

• It is advisable to use them with Metabo’s original spring components to maintain constant pressure on the carbon brushes.

These carbon brushes are TÜV-certified and comply with the EN60745 safety standard, making them reliable spare parts for maintaining the performance of professional tools.
