Milwaukee® 22-18-0680 Replacement Carbon Brush Assembly, Use with 5223 Serial 584D 5 in Straight Grinder

Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks or other damage which can indicate larger motor problems.
