Milwaukee Carbon Brush Assembly - 230V
Model Number: 22-18-0590
The Milwaukee 22-18-0590 is a genuine OEM Carbon Brush Assembly for 230V Milwaukee tools, the motor brush that maintains electrical contact with the commutator inside a corded, brushed-motor tool. As the motor's armature spins, the carbon brush rides against the commutator and transfers electrical current into the rotating armature, which is what makes the motor turn. The assembly includes the carbon brush along with its lead wire and the spring that keeps the brush pressed against the commutator with consistent contact pressure. This brush is specified for 230-volt tools, the voltage used in international and export markets, and the voltage rating matters: a brush is matched to the motor it serves, so a 230V brush differs from the 120V version, and it is important to confirm your tool is a 230V model before ordering this part. Carbon brushes are the single most common wear item on a corded power tool: they gradually wear down as they ride against the commutator, and as they reach the end of their usable length the tool begins to lose power, spark or arc at the motor, run intermittently, and eventually stop running altogether. Replacing worn brushes with the correct genuine Milwaukee OEM assembly restores full motor power and smooth operation, and doing it before the brushes wear completely away also protects the commutator from damage.
Please note that brushes are used in pairs. A brushed motor has two brushes, one on each side of the commutator, and this assembly is sold individually as a single brush, so most tools require a quantity of two for a complete brush service. It is best practice to replace both brushes at the same time, since they wear together, so that the motor has two fresh, evenly matched brushes. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, and because carbon brushes are specific to the motor and voltage they serve, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct brush for your 230V tool. Do not order by appearance, since brushes that look similar differ in size, lead configuration, spring, and voltage rating. After installing new brushes, run the tool briefly under no load to let the brushes seat to the commutator for best contact and performance.
