It's not just a case of having the inserts sent to you, you will also need the correct oversize drill, the correct tap for the coil, and the insert tool to wind it in.

I have M3 kit at home, so if you want it done, PM me, and send it over and I'll do it for you.

When I said I have helicpols down to 3mm I have full kits down to 3mm
