Common motor
This type of motor is used in many battery operated tools such as drills, etc. I needed it to power a lead screw on a custom cutting machine that I made. The motor has been working flawlessly.

Not big enough motor
This motor was not a replacement motor for Dewalt drill.It was way under sized and do not even have teeth or gears on a shaft

Not sure if this is going to work.
Item received was not new it appears used. Terminal points have pre-soldered wires snipped off. The packaging was torn open.

Not as described
The D motor shaft turned to rounding the flat edge thus does not hold the gear solid and spins with any resistance. Guess only option is to try J B Weld to fill in the open spaces, otherwise Amazon has a sale coming up on the 7th

Good motor for wide range of projects
Updated review, after a small issue with my order, i was contacted by the seller and they kindly took care of the issue providing a new item... customer service was quick and considerate... would definitely do business with again!

I've needed this motor
What I like about this it was very easy to install. I wish I had found it sooner this drill has been sitting here for the last nine months needing a repair. I'm so glad that I finally found it and it was very easy for me to install. If you don't have mechanical skill you might want to have a friend try it for you but it was so easy to use on one of my Craftsman or Firestorm drills because I think the names are combined together. I wish I had taken a photo before I installed it but I'll take a picture of my drill

B&D Matrix 20v motor replacement
Bought this to replace a motor in a black and decker Matrix drill I burnt out. Works great, direct fit.

Arrived broken and poorly packaged from manufacturer
The motor casing is broken and the electrical terminals appear to have been used suggesting that the motor isn’t new as advertised and it arrived poorly packaged by the manufacturer

Really good motor. Used it to convert a 7.2 volt lincoln grease gun to use a 18 volt milwaukee battery. Exactly as described and strong performance. I reccomend.

I bought two of these motors to put in my sons ride on atv for an 18v upgrade. They work very well with lots of torque and great speed!
