I bought this set a few months ago and wanted to use it a bit before reviewing it. After two months I can't recommend this set to anyone. The 1/2" "-Drill is not centered and wobbles a lot when rotating. The rest isn't very sharp, but it's an inexpensive set so it doesn't matter. Just yesterday I had my first chance to use an 1/8" bit and I barely touched the top of the tree before the bit broke right where the shank meets the start of the groove. I drilled perpendicular to the workpiece, there were no knots or hidden metal or anything, just transparent softwood. Overall not impressed.
