I have a quantity of circular stainless steel discs that I need to do a simple engraving onto the face.

The max rpm I have is 3500 from a Syil CNC X3 mill & currently I have no flood coolant.

I've experimented today with what I have, a 1mm HSS ball cutter & a can of WD40 with surprisingly good results, tool held in the original X3's drill chuck !

Having just got the machine, & running several projects at the same time, I'm suffering a severe case of information overload. I have the £cash but I don't have the time to spend on the learning curve to discover which tool & holding system is best suited to this type of work.

Can anyone recommend anything available in the UK ???

I'm also after a range of base colour engraving paints, a Google search throws up nothing but another learning curve. What's the best engraving paint available in the UK ????
