Title: Not very durable.
Product review: Product shipped quickly and arrived as expected. I used this on sanke keg walls, after just a few uses the bit wore down and was not able to penetrate any longer. I ended up buying a different brand from my local hardware store in a hurry. Once the bit wore out, it also had the effect of hardened the metal I was trying to drill.
Would you say this review depicts the product in a flattering or unflattering light?
