Excellent price for a 'rough & tough' borer
Excellent price for a 'rough & tough' borer. It digs in and makes holes easy. Stays sharp even after encountering nails.

Best on the market, cant go wrong with these.
Its a greenlee nail eater.. best auger bit they make. nuff said. I bought this one to replace one that had been used almost daily for 2 years without sharpening. Theyre awesome, and you can hit nails with them and the bit will survive, but they last a lot longer if you avoid the nails

Great product.
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 !

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.

Beautiful tool. The price was stupendous
Beautiful tool. The price was stupendous, though it went up a lot after I bought the last one. Made In USA quality for less than Chinese price. Now I hope I won't break my arm when this grabs and the torque on my drill goes to work. Actually cut so well and didn't grab at all like I though it might, wonderful product.
