[RE-wrenches] Nuance ground racking

[Jason Szumlanski]

These work well for smaller conduit but when you get into 1-1/4" and
greater trade sizes, especially when you need to get a fitting into the
wall, I think you need to go to core bits. I don't think they make spiral
bits that big with SDS shanks, but I could be mistaken.
