My wife uses a a card cutting machine (craft robo) which works well for THIN card, sadly however the blade diameter is too small for my i/8" collet chuck.

Dremel and others make a very small 3 jaw chuck that might hold .5mm you might be able to hold the chuck in your collet with an adaptor. Just a thought. ..Clive

Thanks Clive. You have slightly mis-understood what I meant. I use PCB type end mill cutters which all have 1/8" shanks. The 0.5mm cutters have a very short length of cutting flutes so the broken ones leave quite a long length of 1/8" solid carbide shank to regrind as a dragknife with a decent offset to get the knife to follow. from what I read into the comment from Jazz, this may well work, but would benefit from using a modified G code.

Yep Geoff if you watch the video carefully you can see the machine Jiggle at the corners doing very fine moves so the blade orientates to the direction to cut.
It almost looks like Tangential knife because blade spins before moving in direction of cut but the rotation comes from the machine movements not the spindle and the blade is just held in an Offset holder which spins in bearings held in outer assmebly that's held in spindle collet.

Without this extra code to orientate the blade it can tear or pull sharp corners.!!
