The drill itself is fairly easy to set up and use. For some of the larger diameter drill bits, I had to pre-drill the smaller drill bits to allow the larger drill bits to go through the wood. Otherwise it will be difficult to get enough momentum to start a hole. There are two sets of bits in the box: a larger diameter set, closer to what I'm used to from my drill press, and a smaller set, some of which are as thin as needles. The smaller ones are brittle and I have half a click the first time I use them. In addition, if you're not careful enough, it's easy to accidentally unscrew the drill while you're using it, since it's easy to grab the end near the drill when the drill is spinning. what my urgent need was.
