This drill bit does not meet expectations for Industrial and Scientific drilling applications. Through trial and error, I found that the bit quickly became dull and unreliable. While inexpensive, this product may cost more in the long run due to its poor durability.
The first thing I tried was not to drill 24 gauge aluminum. Just twisted. So I tried the rest. Of the 10, 2 were sharp, 2 were completely dark, and the rest were almost dark. waste of money.
The first drill I tried was nice and sharp and the drill is perfect. The other nine have to wait because drill #1 is still sharp. I chose this size because it is a universal size that fits most lead diameters.
