Piercing

[alexf]

I have been using a Dremel for piercing but would like more accuracy. To this end I purchased a dental drill with ceramic bearings and a generator driven led. My problem is connecting it to my compressor. The fitting is roughly 13mm dia with a very fine thread. I cannot find any adaptors which will fit this. Does anyone have any ideas where I would get one?

I was looking at these last night. I think you'll need to get the tubing with the connector attached. Pretty sure you then have to alter the connector to use it with a single tube.

The video is heavy going, but from about 35 mins onwards he talks about the connector & tubing.... https://www.youtube.com/watch?v=5P8Zh_pI-tU

p.s. if you search Fleabay for 'dental tubing' you should find what you need.

1/4" BSP is around that diameter and commonly used for air tools.
