Review on Superior Electric SEWA20 Adjustable Lock Nut by Jeremiah Vishwasrao

Lost the original key for my rotary sander. This worked great to replace the drive for my next job. . and it was the cheapest option. Plan to use it many times in the future. A downside might be the thumbscrew, which doesn't seem to grip the clamps to lock the jaws, so it can slip under torque. but the tool somehow worked without dangerous slipping. we'll definitely see how long that lasts!
