Deep Hole, Short Bit
October 7th, 2008How?
Surprise me tomorrow morning with some information. How do you drill a 10″ deep hole in concrete with a coring bit that is 4″ long? Seems like long bits are hard to find.
I was thinking there must be some kind of bit extender, and that every time the bit bottoms out, you could knock the core out with a chisely shaped sort of a thing.
But maybe it’s impossible.
