Review on Lenox Tools 1779670 Arbor 4 Inch by Todd Look

Terrible tool. I've read great reviews of this particular adapter but it got me into a huge dilemma when I needed it most. There is a screw that holds the cartridge in place and I didn't realize the screw was missing on arrival. So when drilling with my hole saw, the drill chuck slipped back and the saw blade screwed so hard into the mandrel that it was impossible to remove the hole saw from the mandrel. Very disappointed with this tool. I ended up having to replace the hole saw blade with an unusable mandrel.
