poor durability- don't waste your money

I got three holes chamfered with this bit before it stopped working well. this is not acceptable durability and I won't buy it again. we were only chamfering 1/8th inch mild steel. very frustrating that we finished the job with a larger drill bit. I I bought this bit thinking it would speed up our process! wrong!

Glad I bought it.

Paid for itself pretty quickly. Only issue I had was getting it delivered from Lowes. Should have been delivered Saturday, didn't get here unit the next week which delayed my project.
