I'm posting this here because I think the technology would work great on
There is no massive chip build-up issue with wood and the hole size could
theoretically be increased by quite a bit with the HP and thrust ratings we
are capable of.
If someone had a high volume, larger hole process to perform over and over
again in an automated fashion, this could be a great option.
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 when drilling metals
given the different diameter holes that can be drilled, etc. See the
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.
Will try to answer any legitimate questions asked and of course would
welcome ideas on the chip build-up issue in metal. I presume it would be
even worse in plastics, etc.

Two suggestions for chip buildup - 1) high velocity vacuum. That is,
a vacuum system with a nozzle near the cutting head that is capable of
drawing the chips in at a high velocity. This gets them away from the
immediate area around the cutter: A more conventional chip/dust
collection system could be used downstream. 2) well, if you can't
suck, blow. Blow chilled air onto the cutter. Chilled air will also
help keep cutter heads cool and make them last longer, and may reduce
resin build-up. If you have compressed air (and I bet you do), you
can attach a Ranque-Hilsch vortex tube to a compressed air line
(see:http://en.wikipedia.org/wiki/Vortex_tube). Here's a company that
sells them - http://nexflowair.com/vortex_tubes_and_spot_cooling.php -
google for more venders.
The Vortex coolers do a good job. So does a high velicity air blast or
vacuum. However, the steel chips are simply too heavy for most of these to
work well. Wood, no problem at all I'm thinking but we will run a test to
How about putting the depth control rod closer to the drill bit? You can see
the spirals that get close to it breaking off. If not the depth control,
then something else in the path of the chips to break them into smaller
