This is one of the most common questions we get asked and it is very hard to give exact feeds for every tool. Tools with smaller angles and tips are more brittle and should be run slower. Another factor is the depth of plunge, if you are only cutting 1mm deep you can run at a much faster speed. When cutting 3mm or deeper try slowing your feed and plunge rate down. We also recommend that you use our cutting oil, even when milling wax. The oil will make cleaning your wax much easier and your tools will last longer.
