[sarasabrownie]

I am going out of my tiny mind trying to find a set of 2.5mm HOLLOW, diamond-tipped drill bits that I know for definite will fit my Dremel 4000. I even followed a link on a website that allegedly linked to an amazon page selling them but was bombarded by kits and drill bits that needed Collets and drill bits that weren't hollow.

I am trying to avoid buying directly from

oops butter fingers - am trying to avoid buying directly from Dremel as everyone says theyre really expensive but I can't even find them on their site.

Can anyone help??
