Hi all,

Wondering if you could help. I am looking to purchase a burr cup in 0.8 to round the ends of ear studs. I want to use it in conjunction with my Foredom.

Would either of these be suitable as I know the shank needs to be a certain size but can't work out the inches conversion.

Thanks in advance.
