Makita carbon brushes are an important service component in many corded and brushed power tools. Over time, carbon brushes naturally wear down through contact with the motor's commutator. When they become worn, replacing them can often restore the performance of your Makita tool without the need to replace the entire machine.
If you're looking for Makita carbon brushes, the most important thing is finding the correct brush for your particular tool. Makita uses many different carbon brush types, so brushes that look similar may not necessarily be interchangeable.
Carbon brushes are small components found inside the motors of many brushed electric power tools. They transfer electrical current to the rotating part of the motor, known as the armature.
Because the brushes are constantly in contact with the rotating commutator, they gradually wear down during normal use.
Once the brushes become excessively worn, the tool may begin to show symptoms such as:
Replacing worn Makita carbon brushes can be a relatively straightforward repair on many tools.
Carbon brushes are a wear item, so eventually they will need to be replaced.
One of the easiest ways to check them is to inspect the brushes according to the manufacturer's service instructions. If they have become very short, damaged or are no longer making proper contact with the commutator, replacement may be necessary.
However, a tool that isn't working does not automatically mean the carbon brushes are faulty. Problems with the switch, power supply, armature, field coil or other components can produce similar symptoms.
If you're replacing brushes and the tool continues to have problems, further investigation may be required.
The easiest way to find the correct Makita carbon brushes is to identify your tool's model number and then check the relevant parts diagram.
Makita carbon brushes are commonly identified by a CB number, such as:
The CB number identifies the brush type, while the longer Makita part number is the number used to identify the specific replacement part.
For example, CB-440 corresponds to Makita part number 194427-5 and is used across a number of Makita cordless tools, including the DDF456, DDF458, DDF482, DHP458 and DHP482.

Not all Makita cordless tools use replaceable carbon brushes. Many newer Makita machines use brushless motors, while older brushed cordless tools use replaceable brushes.
Some popular replacement brushes for brushed cordless models include CB-430, CB-440, CB-441, CB-442 and CB-448.
For example, CB-440 / Makita 194427-5 is listed for models including the DDF456, DDF458, DDF482, DHP458 and DHP482.
If you're unsure whether your cordless tool has replaceable carbon brushes, check its parts diagram before ordering.
Angle grinders are among the Makita tools where carbon brushes are commonly replaced as part of normal maintenance.
Popular brush types include:
Always check the exact model before ordering, as similar-looking grinders can use different brushes.
Many older and current brushed Makita drills and hammer drills use replaceable carbon brushes.
Some commonly encountered brush types include CB-64, CB-85, CB-325, CB-419 and CB-440, depending on the particular model.
For example, CB-419 / 191962-4 is listed for models including the HP2050, HR1830 and HR2020, while CB-440 / 194427-5 is used on cordless models including the DDF458 and DHP482.
This is a common source of confusion when searching for Makita carbon brushes.
The CB number identifies the carbon brush type, while the longer number is the Makita part number.
For example:
CB-440 → Makita part number 194427-5
When searching online, either number can help you locate the brush, but searching by the complete Makita part number is generally the safest way to identify the exact replacement.
Carbon brushes are normally supplied and fitted as a pair because a motor has two brush positions.
If one brush is significantly worn, it is generally sensible to inspect and replace the pair rather than continuing to use one heavily worn brush alongside a newer one.
Always follow the appropriate Makita service instructions for your specific tool.
The exact procedure varies between Makita models, but on many machines the brushes can be accessed through brush caps or by removing part of the tool housing.
Before carrying out any work:
If you are not confident working on electrical power tools, use a suitably qualified repair professional.
Finding the correct Makita carbon brushes doesn't have to be difficult. Start with the model number of your tool and check the relevant Makita parts diagram.
Once you've identified the brush type and Makita part number, you can search for the correct replacement with confidence.
Whether you need carbon brushes for a Makita drill, grinder, saw, sander, planer or cordless power tool, replacing worn brushes can be a cost-effective way of extending the life of your machine.
