Dont waste your money at an new expensive drill!
I have fu**ed up about 6 drills or more in the last years. Believe me, they wont run much time. And about 2500upm is enough. Buy a cheap (used) drill at ebay or so.
I have also killed a new die grinder from a big company in less than a half year.
So i would recommend a cheap drill or you spend big money on a professionell flexible shaft machine. I did it, and i dont regret my decission till now...
