Gets the job done
Drilled through thick steel without much trouble. I did use cutting oil and went slowly. Perfect for my needs and a good price compared to brands like Milwaukee.

Does what its supposed to do.
Cuts through sheet metal with ease. I have used Irwin and I have used Klein unibits. The Irwin bits stay sharper longer.
