## Long description

Replacement carbon brush set Makita CB-419 (two pieces) designed for use in compatible Makita power tools. These carbon brushes restore electrical contact between the stationary and rotating parts of universal and commutator motors, ensuring stable commutation and reducing sparking and power loss when original brushes are worn. The set is intended for routine maintenance and repair of drills, grinders and other rotary motor-driven handheld tools that use replaceable carbon brushes.
Advantages
The two-piece carbon brush set provides a straightforward, cost-effective way to renew motor contact surfaces without replacing the entire motor assembly. Made to match form and function requirements of compatible Makita tools, the brushes help restore reliable motor performance and reduce intermittent operation or overheating caused by degraded brush contact. Installation of new brushes can also contribute to longer overall tool life and more consistent torque under load.
Suitable for
 Routine maintenance of hand-held power tools with commutator motors
 Repair of drills and impact drills with replaceable carbon brushes
 Restoring performance of angle grinders and sanders with worn brushes
 Workshop servicing of rotary-motor equipment that exhibits sparking or power drop
Key specifications
 Contents: 2 carbon brushes (complete set for one motor)
 Brush material: conductive carbon composite suitable for commutator contact
 Typical application: small to medium-sized universal/commutator motors in handheld tools
 Mounting: replacement type with terminal or spring connection compatible with specified tool models
 Function: restores electrical contact for proper commutation, reduces sparking and power loss
How to use
Before replacing brushes, disconnect the tool from the power source or remove the battery. Access the brush holders by removing the appropriate cover or end cap according to the tool’s service instructions. Remove the old worn brushes, noting orientation and connection method, then insert the new brushes from the set into the holders, ensuring correct seating and secure electrical connection. Reassemble the cover and test the tool under no-load conditions to confirm smooth commutation and absence of excessive sparking.
Usage recommendations
Replace both brushes at the same time and inspect the commutator for wear or scoring. If the commutator is heavily worn, have it serviced before prolonged operation. Use the carbon brush set for scheduled maintenance intervals or whenever you observe excessive sparking, reduced power, or intermittent motor operation.
