Hi. May I know where to buy the tool you're using at time 3:00 in this video?

[@fearlesswei]

have you found out what the tool is?

Hi Guys,
I know its a bit late but the tool he is using is called a ''grommet grinder''. I've never seen such a nice metal one before but you should be able to find similar versions using that name.
