Hi,
I keep seeing sets of these (reduced shank drills) at very reasonable
prices cf taper drills and I wondered if anyone here has any experience
of them in a model engineering context ? One possible drawback that
occurred to me is with a shank of around 12mm an eg 20mm drill is going
to exert quite a large torque and might move in the chuck, is this a
real problem ? I'm also interested to know what use they are actually
intended for (yes I can already guess blacksmithing :-)
Thanks,
David

We have a selection that we use here, we can drill paxolin or wood
with the larger sizes, but the most useful ones are the 9/16" and 5/8"
which can be used on steel with a decent pillar drill.
If the chuck is tightened securely there is no problem unless you are
going mad, in which case the chuck or its mounting will suffer.
