I had some Ryobi and was/am disappointed with them.

MonteCristo is correct with the one size does not fit ; brad point, Forstners, and twist drills are all useful in woodworking. I use my brad point bits the most since they are much easier to locate on the center mark than a twist drill.

My brad point bits are Irwin (very old set) and the sizes are marked as inch but they do not really measure out to inch dimensions and I assume they might be closest metric equivalent.

I have a set of Forstner bits I bought a Costco and I am very happy with them!

Mike is correct about a sharp bit, you will burn wood, possibly damage you project, and open yourself up to possible injury using a dull bit!
