🔧 Bosch HE1 Hole Enlarger Set Review

We bought a house and wanted to replace an unknown brand of door handles with Schlage which required enlarging the hole through which the handle assembly fits. It's pretty hard to do, and if you mess it up, you'll ruin your door. So you use a hole enlarger to keep the center of the hole right where it should be. It worked like a charm to enlarge the doorknob hole.

I just received this item so have not used it yet. As is usual with this type of tool, buy it "after" you really need it. All I can say when I put it in is that it's solidly made. The concept is simple so I'm sure it will work as advertised. What I really like is that 2 saws with rails of the same diameter can be mounted on it at the same time. This applies to both larger and smaller sizes. Of course, you can also use saws of different sizes. It also has a good mount to fit snugly on the saws…

This worked well to widen some old door handle holes. The main problem wasn't apparent until I tried to take the thing apart. Since the hole saws screw into the base, you'll need to remove the inside first. However, since every time one of the saws makes a cut, it tightens more and more, unscrewing it will not be difficult. In my case, a maximum of 1/8" of the internal saw is exposed, meaning it's impossible to snag. Add to that two rows of sharp teeth and this thing seems impossible to remove.
