Hi All - in recently bought a box of assorted auger bits. Among them were a few big uns - 24/16, 32/16 and 40/16. They are all square tanged. The 40/16 was made by Greenlee - I'll have to double check on the others and get a few photos.
Googling about, I was not able to find other examples of bits this large. Are they unusual, or am I just looking in all the wrong places?
