Check out this link for a 2" hole being drilled through a 3/4" piece of
steel with the 5160-x series AutoDrill.

We haven't quite solved the chip build-up issue yet given the different
diameter holes that can be drilled, etc. See the problem he

We think that either a stationary bar next to the tool or some type of
peck
cycle will help solve the issue but given the fact that we're two days
into the 2" diameter process, I figure we're doing okay.

Note that the chip issue in the first video is solved by having an
interrupted cut. In other words, the large 2" hole intersected with a
another hole just ever so slightly so that the chip was not continuous.

Would love thoughts from the experts on the chip break issue. Will try to
answer any legitimate questions asked.

What if you had a separate air valve that went between the "cylinder extend"
and exhaust. Then pulse the valve to oscillate the pressure on the feed
cylinder.
