Milwaukee 230V Carbon Brush Assembly
Model Number: 22-18-1015
The Milwaukee 22-18-1015 is a genuine OEM 230V Carbon Brush Assembly for the 4270-50 Mag Stand Assembly, the 230V version of the Milwaukee magnetic drill press. A carbon brush is the wear component that conducts electrical current from the tool's stationary wiring to the rotating commutator on the motor armature, which is what keeps the motor turning. Each brush assembly includes the carbon brush with its lead wire and spring attached, and the spring holds the brush in constant contact with the commutator as the brush gradually wears down. Carbon brushes are one of the most commonly replaced power tool parts because they are consumable: through friction and use they wear away over time, and a worn brush is a common cause of reduced motor power, intermittent operation, and weak or inconsistent electric braking.
This is the 230V version of the brush, matched to the 230V 4270-50, so confirm your tool's voltage and catalog number before ordering, since the 120V version of a tool uses a different brush. Brushes are sold individually, and most motors use two brushes, one on each side of the commutator, so it is recommended to order and replace both brushes at the same time so they wear evenly and the motor runs smoothly. A worn brush is typically worn down close to the lead wire and may be cracked, pitted, or burned. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number. A screwdriver and pliers are typically needed to access and replace the brushes.
