Diablo 1-1/8 in. Dia. x 2-3/8 in. L Bi-Metal Hole Saw 1 pc.

from Andrew12

I only needed to make a few cuts and on the first hole half the teeth broke off and the pilot bit snapped

from Cosbon

I bought a 1.75” and a 2” as well as the arbor kit. Both hole saws are missing at least 6 teeth. The drill bit that came with the kit bent. And then I snapped a second bit off inside the arbor making it useless. Not a single hole sawed. They saws literally scratched the surface and that's it.

I bought a set of these for installing locks (I am a locksmith) and I like the design, it is robust and allows quick changes of the saw with the same mandrel which greatly appeals to me because it means I can eliminate some weight in my toolbag. One 2,1/8" saw and a 1" saw, one mandrel. Less stuf...

I have never so happy with a hole saw before no more looking around for all the parts to put it together or the chuck to get the pilot bit out just snap and drill. When looking for cutting tools there is no need to look at any other tools.
