Product Information

Product Number: N257540

Classification: Part

Weight: 0.01 lbs.

Also Known As: Motor Brush

Shipping: Ships Worldwide

Description:

Genuine Dewalt replacement part used on Small Angle Grinder. This brush has a lead wire attached and it is Sold Individually. It is always best to replace both brushes, even if only one is worn.

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.

Grinder not running

Bought brushes from replacement parts at a very fair price. Had grinder running in 10 minutes.

Jim - October 15, 2019 Verified Purchase

Order two!

Not sure why you would only replace one brush or what motor only uses one brush. Need two!! They fit great easy install and worked great.

Guest - September 9, 2019 Verified Purchase

Great parts at a good price!

ordered a quantity of brushes, should've ordered what you had in stock first then ordered more. Would've gotten a few earlier but not a big deal. I never had to return anything!
