Milwaukee Carbon Brush and Spring
Model Number: 22-18-0910
The Milwaukee 22-18-0910 is a genuine OEM Carbon Brush and Spring assembly for Milwaukee brushed electric power tools — the factory-correct replacement for the carbon brush wear component that maintains electrical contact between the tool's stationary power circuit and its rotating armature assembly during tool operation. Carbon brushes are the primary consumable wear component in brushed DC electric motor tool designs — they are blocks of compressed carbon compound held in contact with the rotating commutator surface of the armature by a spring, conducting the electrical current that powers the motor's armature windings through the sliding contact interface. As the brush operates in contact with the rotating commutator, the carbon material wears progressively through friction contact, gradually reducing the brush length over the tool's operational service life. When the brush wears to the minimum usable length, the spring can no longer maintain adequate brush-to-commutator contact pressure for reliable current transfer, causing the tool to run intermittently, lose power, or stop running entirely. Replacing worn carbon brushes with correct-specification genuine Milwaukee OEM brushes before they reach complete failure restores full tool performance, prevents armature commutator damage from arcing that occurs with worn brushes, and extends the total service life of the tool at a fraction of the cost of motor assembly replacement.
This listing is for one carbon brush and spring assembly — Milwaukee brushed motor designs use two carbon brushes positioned on opposite sides of the armature commutator. Both brushes accumulate wear at approximately equal rates during normal tool operation, so when one brush reaches minimum service length, the other typically requires replacement simultaneously. Always replace both carbon brushes at the same time, even if only one has visibly worn to minimum length, to maintain balanced current delivery to the armature and prevent single-brush operation that causes accelerated commutator wear. Carbon brush specifications — including brush compound formulation, brush block dimensions, and spring tension — are engineered specifically for each motor design and cannot be substituted between different motor applications. Always verify your tool's exact model number and serial number before ordering replacement brushes, as Milwaukee carbon brush part numbers and specifications vary not only between different model numbers but also between production serial number ranges within the same model when motor design revisions were made during production.
