One size will do most. This self-centering bit is just right for most interior door hinges. A centered hole is important to getting the hinge to seat properly and that is what this tool is for.
Hey, I am good, and never mkae mistuckes, but it is better to have help than make a mess of the job. I have more than 10 doors to do and do not want to need to patch an offset screw hole.
There is also a 3 size kit, but this will do my job.

I have been using this bit for years. I always keep one in every tool box I have. It is the best way to center a drillbit when redrilling henges. Always perfect!

As a female with limited carpentry experience, I found this centering drill bit very helpful in installing new cabinet doors. Since the doors are inset and have butt hinges, accuracy was very important. This special tool kept the bit from bouncing and getting the hole off center. You have to be careful not to drill the hole deeper than the length of the screw, but otherwise, this bit, which is sheathed in a cylinder that fits precisely into the hinge holes, takes a lot of stress out of the job.

When I received the unit, the drill bit was sharpened way off center. I resharpened it. Easy to disassemble and work on. After that, it drilled 1500 holes in oak without issue and can drill amny more. It would be better to sharpen it correctly at the factory, so I gave it a lower quality rating.

Must have if you are centering holes for hinges, door locks and strikes. Please put these back in the store.
