Reviewed in the United States on July 20, 2018

I successfully drilled that hole, and this drill bit did not have any problems.
I have no idea how this compares to other, similar drill bits, but it was one of the cheapest options. Also, I have been buying only Bosch wiper blades for the cars for several years now, and I firmly believe that they are significantly better than others I've used (Anco maybe?). Not that automotive wiper blades are relavent here, but I have some faith in the integrity of Bosch products based on their wiper blades.
I suspect that this drill bit will have years- maybe even decades- of infrequent use. Also, I'm totally prepared if anyone ever asks "hey- do you have a really long drill bit that I can borrow?"
Don't forget to support this as you start into material, these are not precision balanced and will "whip" and bend at high speed if you don't use a guide system.
