Jeweler's Tools in the UK...?

hi there. You can get cup burrs and almost any other tool you will
need at Cooksons Predious metals in Birmingham. I think their email
address is Tel. 0121 200 2120. The item
you want is CUP: Busch No. 411, but they come in a range of sizes
from 1mm to 6mm diameter. The cup burrs don’t have a handle as the
one illustrated on the website you indicated, but you can buy a
wooden handle or a Pin Vice, to hold it. Hope this is of some help
to you. Contact me if you need any more info.
Cheers and good luck from Ruth (burning the midnight oil) in
