I have only used the small bit but I can say it was worth the $. I always had trouble getting a good centered hole. Not anymore!
A woodworkers must have

I have had many troubles in the past trying to get the screw hole drilled in the center of my hinges. Not anymore. These things work great. I saw other reviews about broken bit trouble but I have yet to have a problem with mine. Sure the collar may stick a little when wood gets wedged inside it but that is understandable. I will definitely be using these on all of my hardware projects where a centered hole is needed.
Great product at a great price....

Great product at a great price. If you need pilot holes dead center then you need this. It just makes hinge installation so accurate and so much less stressful and your projects much, much better.
