    Nothing seems to dull it.

I also wrote a review on Greenlee's shorter auger and I'll just repeat some of it here. This bit is tough. I know it's designed to chew through steel nails but I pushed it much harder than that, and it survived. I used it to drill out a wooden 4X4 post embedded in concrete. As I drilled, I repeatedly hit the sides and tip of the bit into the concrete. The surprise came when I examined the bit after this abuse only to find .....nothing. The bit was as sharp as new. No damage whatsoever. Even the screw tip was unscathed. Now I'm not saying it should be used in place of a true concrete bit. That would be silly. But if you need a rough-tough auger, then Greenlee is the way to go.

    Great product.
  

*by S***M on Reviewed in the United States on July 1, 2020*

I have used Greenlee  Electrical products for over 50 years and never ever had a bad product from them. They are a bit more money than some brands and worth every cent of it !
