NOT WORTH A PRICE! I rarely write reviews but I had to warn people about these cheap tools. I only bought this one as there aren't many options for this size. The drill cuts horribly with a hand drill. The punch jumped and broke my wrist, ripping a hole instead of cutting through. The last hole was far from the right size. The chisel grabbed, bounced and flew out of the hole, repeatedly damaging/going through the wood around the hole. I tried it on a drill press but after a cut in oak the drill was dull, fried, smoked and still hanging and dangling and didn't cut smoothly. Back to hole saw and chisel. I will not buy any more products from this company.
