The photos from Revain's list show a QUALITY pilot drill set with QUALITY laser engraving to clearly identify the pilot drill size. What you get is a cheap set of center drill bits with markings that you CANNOT read clearly. In some cases the smaller center drills have NO marking at all. In addition, the center drill case is too small to store the center drills. Sharp precision center drills rattled in the container during shipping. There is NO way to separate the center drills from each other in the container. The photos CLEARLY show that the center drill bit set you received does NOT match what is shown in the Revain photos.
