Unfortunately, I got a defective bit (the slot on the bit was not machined correctly), so the tool wouldn't lock in place. This resulted in the tool pulling out of the hammer when trying to remove it from the soil. I plan on getting a replacement, because the tool is great.
One improvement for this particular tool would be to have a longer shank. Since this tool is made to cut through "soft" material (soils), it can quickly bury itself down to the drill. A longer shank would make this less of a problem.
My only advise is to make sure the hammer is set to the slowest speed. Used it the first time with my brand new demo hammer. The speed was set on high. It all happened so fast, and into the clay it went. I ended up having to dig the hammer and clay spade out with a Mattock pick
