Will do the job. I really only needed a 30mm bit but I bought this set. Unfortunately they are pretty dull compared to most bits I own. It took a lot more pressure than I wanted to get through the base 1/2" MDF. It would have been nice but after 14 holes I was a little tired. Also my drill bit was overheating by this point. My normal 1 1 /8 bit was much faster.
