davec Posted January 31 Author #31 Posted January 31 The tube segment that need deburring are .5 mm tube (.3 inner diameter) and are 4 mm long. Is there a rotary cone bit small enough? I can see using a rotary tool on the free end before cutting the segment, but any suggestions for holding the short tube to use a rotary bit on the second end once the segment is down to 4 mm? thanks!

wefalck Posted January 31 #32 Posted January 31 Cones go down to near zero (at least, if one has quality ones). I am holding both, the part and the bit in pin-vises respectively. Egilman, king derelict, Canute and 1 other 4 wefalck panta rhei - Everything is in flux
davec Posted February 2 Author #33 Posted February 2 Welfalck- again, many thanks. I have some small rotary cone bits, although I don't know about quality. I just had some surgery , so it will be about a month before I get back to my workshop. Will give it a try then. Looking forward to seeing if seating 30 4 mm tubes in the pin vice for using the rotary tool is easier or harder than holding them by hand and using a hand held drill.
