You are probably correct. I have non-removable tips, and had to use a 12" bit.. so my angle was very shallow and so my holes are further back then I think they should be. But, looking at the cutaway picture, it looks like any hole into the middle chamber should work...

After driving it today... there is a difference. Not much of one, but there is a difference. I think I need a bigger drill! :-)

I was having a tough time getting the angle with my fixed tip 98 and a 6" long bit. I stopped before I caused any damage.

Any fixed tip guys have recommendations or pics of how they did it?
