Makita CB-55 Crimped Wire Carbon Brush Set

Key specs and features include high-quality carbon brushes for efficient power transfer, durable construction to withstand wear, easy installation for quick downtime reduction, compatibility with a wide range of Makita tools, precision engineering for higher conductivity and reduced friction, compact packaging for easy storage, and a cost-effective replacement that supports safe, reliable operation.

The CB-55 set is designed for use with a broad range of Makita tools that use crimped wire carbon brushes. It provides a precise fit and optimal performance by matching the brush size and contact geometry required by Makita motors. For exact compatibility with your model, confirm the brush type and size specified in your tool’s manual.

Power off and unplug the tool, open the motor housing, remove the old brushes and springs, inspect the springs for wear, install the new CB-55 brushes ensuring correct orientation, reassemble the housing, and test the tool for smooth operation. Handle brushes gently to avoid breaking delicate contact surfaces.

You should notice more consistent power delivery, smoother motor operation, and reduced signal loss as the contact between the brushes and commutator improves. This can translate into restored tool performance and longer motor life, especially in demanding or continuous-use scenarios.

Common signs include motor performance drop-off, reduced power or efficiency, unusual sparking at the brush area, or visible wear on the brushes. If the brushes look worn down or the tool exhibits inconsistent function, it’s a good time to replace with CB-55.

Both CB-55 and CB-56 are crimped wire carbon brush sets designed for Makita tools, offering reliable power transfer and easy replacement. The CB-56 may be a model- or tool-specific variant with a different brush size or fitment. For precise compatibility, compare the brush dimensions and the tool models listed for each set.

CB-39 is another Makita carbon brush option, typically offering a different size or fit for specific Makita models. CB-55 targets a different subset of tools. When choosing between them, match the brush size, contact face, and tool compatibility to ensure proper fit and performance.

Ideal for professional trades and DIY projects where Makita tools are used heavily—drilling, grinding, sanding, and cutting applications that rely on reliable motor performance. Replacing worn brushes with CB-55 helps keep tools performing at peak efficiency during heavy use.

Always unplug the tool before service, wear eye protection, and handle brushes carefully to avoid damage. Work in a clean area, avoid forcing components during disassembly, and ensure springs and springs-pockets are reinstalled correctly to prevent short circuits or misalignment.

Yes. Replacing worn carbon brushes with a quality set like CB-55 helps preserve motor life and performance, often reducing the total cost of ownership by delaying expensive motor repairs or tool replacements. It’s designed as a durable, affordable replacement part that delivers good value for Makita tool users.

Avoid installing brushes with incorrect orientation or forcing parts during assembly. Ensure the springs seat properly, verify there’s no debris in the brush pockets, and confirm the electrical contact faces are clean and free of damage before reassembly. Improper orientation or damaged brushes can cause poor contact or motor wear.
