I used this product for installing sprinkler systems easy to use great product...

I like them very well

Great valve and good quality

Does not work with Lenox hole saws. Waste of my time

good replacement for some lost parts.

Great mechanism for release and tightening.

Perfect for cutting through metal frames at work.im an comercial electrician and am constantly useing these wholesaws...

Good product for the value. The Milwaukee is much better quality if you will be using frequently but this is almost 1/2 the price.

Worked great out the box. Easy release system make the job quick. Would definitely buy again.
