Review on 10Pcs Concrete Carbide Plastic Mgtgbao Bits by Lynn Cole

If anyone uses drill bits for anything let me just say you would be determined not to buy this set, these are the best drill bits I have ever bought and used. Wood and Steel I used one of these bits and can't even tell if it was used. Will definitely be ordering more as I bought 2 orders of different sizes, of course I want any size they make.
