Yeah I would probably consider buying a decent milling tool. Intermac and bavaloni make good tools designed for this job allowing internal water to flow through the tool which stops the tool clogging and heating up. External water is a big factor as well. Like a caitolly mentioned high rpm and a slow feed rate will help. The dremel tools you have mentioned should be good enough for engraving. I don't think they would last to long while milling though. Let us know how you go. |
