I bought this item to use with an earth auger although it is designed for an ice auger. I had to modify it to fit by cutting off the area underneath where it attaches to the auger (although this may not be necessary for the ice-versus-earth augers). The steel isn't very thick and is quite soft to the touch, but it worked well for drilling. five 8 inch holes through sandy bottom with some rocks and roots. It showed no significant wear. I'm sure it will work well and last as long as I need it.
