RS-550VC DC 18V Motor Replacement for Bosch DeWALT MAKITA HITACHI HILTI RYOBI DEKO Cordless Drill Screwdriver 18V Motor Tool Part

Successfully used to replace the motor in a black and Decker matrix drill. Will update if there are longevity issues, but the motor appears to work normally. I did have to hammer the little connector gear on to the shaft, which wasn't ideal, but I didn't want to risk heating it to shrink it on, as it had to be done with a plastic piece right next to it.
