I bought my 6040 a few years ago and also bought various Vee bits that I have not used yet.
I want to try engraving some pcb's, but the labels on the bits have fallen off, so I don't know the angles or width of the tips....grrrr

I've worked out how to determine the angles (put 3 or 4 together on the bench. If 3 makes a 90 deg angle they are 30 deg, etc, but I don't know how to determine the tip diameters.

I put the tips against a steel rule and zoomed in with my phone to take photos, but that was inconclusive.
I assumed they would be multiples of 0.5mm but since googling, it appears they will be multiples of 0.1mm. I can't determine that from my photos.

This MIGHT be 0.3mm?
