Got the job done.

Needed a carbide bit to enlarge an opening on my truck frame. Did it's job. Used it with some cutting fluid. Appears to still have plenty of time. Even if this was a one time use, I'm happy with it's performance. Got the job done on something it would've taken me a very long time to do.

Would buy again

Overall a great bit but the teeth chip very easy, I have used it 4 times and even with the chipped teeth it still cuts better than most new ones do

Good for light clean up work.

I used these to clean up casting issues on an engine block. Work great. I don't use them full time and only need them for a few projects here and there so to me they are worth it.

Excellent Quality

Excellent quality. I purchased two anticipating I'd dull one out before finishing my project, but after nearly two hours of continual use, drained three drill battery packs, it's still just as sharp as when I unboxed it. I just put the second unopened one in my toolbox for future projects. When you stumble across a quality tool you hang onto it!
