Brush head Dedra model 13 carbon brush 7x11x18 mm

Carbon brush Dedra model 13, dimensions 7 x 11 x 18 mm, is a replaceable electrical contact part intended for use in electric motors and power tools that accept this size and geometry. The component restores reliable commutation between rotating armature segments and the stationary brush holder, helping to maintain consistent current transfer and reduce electrical arcing when installed correctly in compatible devices.

Advantages

This Dedra brush head is made from carbon material formulated for electrical contact and wear resistance appropriate to small to medium power tools. Its compact rectangular dimensions enable straightforward replacement in applications designed for 7 x 11 x 18 mm brushes. Using a properly fitted carbon brush supports stable motor operation, limits excessive sparking at the commutator, and contributes to predictable maintenance intervals.

Suitable for

• Electric motors in handheld power tools compatible with 7 x 11 x 18 mm carbon brushes
• Repair and maintenance of drills, grinders, saws and similar appliances using replaceable brush heads
• Restoring commutation performance where worn brushes cause sparking or intermittent contact

Key specifications

• Material: carbon (conductive brush material suitable for commutation)
• Shape: rectangular block with chamfered contact face for commutator engagement
• Dimensions: 7 x 11 x 18 mm (width × thickness × length)
• Typical application: replaceable brush head for motors and power tools
• Mounting: designed for holders that accept standard rectangular carbon brushes of this size

How to use

Before replacing the brush, disconnect the appliance from power and, if applicable, remove the battery. Access the brush holder by removing the cover or end cap according to the tool manufacturer’s instructions. Extract the worn brush and inspect the holder and commutator for damage or heavy deposits; clean with an appropriate, non-abrasive method if necessary. Insert the Dedra model 13 carbon brush into the holder with the contact face aligned to the commutator, ensuring secure seating and correct spring tension where present. Reassemble the housing and test the tool under light load to confirm stable operation and reduced sparking.

Usage recommendations

Replace both brushes in a motor pair simultaneously when possible to ensure even wear and consistent performance. Regularly inspect brushes and commutator surfaces and follow the tool manufacturer’s maintenance intervals to prolong motor life.
