Review title: Didn't do what it was supposed to
Product review: I had a simple small job for this bit. To dill about 2mm of a hole with a small amount of the screw left in it. Most of the screw had been drilled out with a smaller bit I already owned from Home Depot. The tip of the bit ground away and didn't make the slightest bit of progress. Worthless. Less than one star really.
