We have been using these for years. They aren't perfect but they are the best you can get for the price. And Red Tool Store is the cheapest we found.
Using my M18 impact I cut 1 hole into 2mm thick mild steel. The pilot bit separated from the hole saw and fell out on the first hole. I pre drilled the center of my holes and continued. I got 1 more hole and the set screw stripped out allowing the round saw to rotate around the shank of the tool. I returned for refund. Hopefully this is isolated. Far too light weight for the power of Milwaukees excellent cordless impacts!
This hole saw only lasted about (2) holes before it gave out. The pilot bit would only continue to spin while the hole saw itself did nothing. It has a set screw that is supposed to hold the hole saw in place but doesn’t do anything once it’s loose. It will not tighten and becomes hard to tighten after a few goes. I absolutely love Milwaukee and it’s products but feel that this one needs to be rethought.
