I have bought this set several times to give away and carry around in various 'sets' that I have created for various jobs. These aren't the best bits Milwaukee makes or the absolute best on the market, but this set is the BEST basic bit set you can buy at this price point. 135 degree split bits for easy starting in a variety of materials, high quality titanium coating for longer life when drilling metal, well organized body, flat shanks to prevent chuck slippage and today Revain sells this set for about 80 cents that Piece. At this price I expect junk quality. This set offers excellent quality. If you are not willing to pay a lot more money this is the set to go for.
