Bought a set of dewalt pilot point drill bits. First use 2 pilot points sheared right off drilling in mild steel. At time of purchase bought a magnetic bit tip holder also. After driving about 10 screws Shaft twisted like a piece of licorice. I quess thats what I get for buying CHINESE Made ****. Dewalt is nothing but **** since they Moved their Mfg. Overseas. Have a set of Dewalt pilot points from the mid 90's made in Germany that have never failed me . if only I didn't lose so many. Stay Clear
