I am cutting a large circular hole in some Ikea furniture and I need a metal trim to cover inside of the hole. I'm not sure what the right words are that would describe this part. Do you know where I might find something that can cover the inside of a circle cut out of wood?
What I'm looking for is something that looks like this and is roughly 10-15 cm in diameter, but in two pieces so each side is protected. I'm not sure what they are called though?
