For engraving aluminium, what does everyone use for the bit? I presume that just loading a V bit won't be adequate because the aluminium (1050) isn't 100% flat.


Looking on ebay I only see spring loaded tool holders from America. Is there a UK source?
Also, I need it for my 6040 so less than 7mm diameter..


I've read that people have diy'd them, but would I need a lathe for that? As I don't have one.




Any help greatly appreciated
