For my mini bench grinder that I rescued from trash, it needed a new pentiometer and new hardware. This fits like a glove, very solid robustly made. Works beautifully. Sized correctly. Very pleased.

Very prompt shipping, excellent sturdy construction, fits securely on my electric motors shaft, and overall is a very good buy for the price. I can now use the motor for a much needed portable drywasher project. Very highly recommend.

Not the size I was thinking they were. I hope this item will fit my small 3" bench grinder if not then I will be returning and getting a refund

Unfortunately for me the 8 mm hole in both of the shaft extenders is slightly oversized so when the set screws are tightened on my 8 mm shaft, the shaft extender is pushed slightly off axis (no longer centered on the 8 mm shaft) from the 8 mm shaft which results in runout and excessive vibration.
