I had yet another failure of angle drill used for sanding. It made 2 Neiko brand that failed in the last 3 months, both being about 3+ years old so not that much a surprise. It seems that all the drills fail with the rear motor bearing failure or the plastic supporting the bearing overheating and bearing wearing out support. I suspect it is a bearing failure. I had a Milwaukee in the past that failed in same manner along with a couple more red and one blue cheapy. Length of service from all seems to be about same 3 years of seldom use with 2 or 3" sanding disks. Maybe the different manufacturers do not get any reports on the types of failure (all same basically) so that they can correct the design problem, or possibly it is a planned failure point to sell more drills. Have others had similar failures?
