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. Peter
