Review on Enhance Efficiency with Drill America Qualtech High Speed Conventional Cutting Tools! by Rene Putman

I ordered 12 drills of 3.05mm and received three 3.05mm drills; six, 3.50mm; and three 3.15 mm drill bits. Worse, most drill bits of any size marked are at least 0.001 inch (sometimes 0.0025 inch) smaller than the listed size. Of the twelve drills, I only got one 3.05mm drill that was the right size. All of them were in an envelope marked 3.05mm. Obviously the quality of the packaging is poor, but the bigger problem is that most of them are too small. These are low quality drill bits and I recommend you avoid this brand of drill bit altogether.
