When setting up my diy pneumatic hand engraver, the hand piece I am modifying came with 3mm tubing and I don't know how to get it up-sized to fit my air supply. Can I drill out the 3mm tubing inlet on the hand piece without adversely affecting performance? What size can I use? 3/8" OD? Thanks for any help.

I will get some pics asap. Everything is working, it just won't cut. I think it may be the crappy graver part.
