Worn brushes are often the cause of a poorly running motor
• Replacing brushes can fix an intermittent motor
• New brushes can restore a motor’s electric braking

Carbon motor brushes are one of the most commonly replaced power tool components.
Because carbon brushes are wear items, meaning that through friction and use they will gradually wear away, they will eventually require replacement.
Worn brushes are common causes of intermittent motor function, reduced electric braking, and reduced motor power.
A worn out brush will often be worn down near the wire lead and may be cracked, pitted, or burned.

When replacing carbon brushes, be sure to also inspect your armature for burns, cracks, or other damage which indicates a larger motor problem.

It is a genuine OEM replacement part and is sold individually. This Ball Bearing is sealed on both sides. Ball bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.
