Hi Wal
Thanks for the links, i'll check them out.Your right about the slow speed. I cut my surname out on Sunday (12 Letters Polish name !) 6 passes with a 0.5mm cutter must have taken 45 mins. My cutters are a bit long so I didn't want to push them too much. The cutters on the apt site are a little short on the 0.5mm dia, only 1mm deep my pearl is usually 1.5mm thick. That surfacing cutter looks really useful.

Cheers

Andrew
