Can anyone identify the manufacturer of these tool holders they are on my Daewoo 2500sy lathe they have no markings at all on them I am trying to find a place to buy more of them I have found some that would fit on the machine but they have bolts that hold the tools in not the wedges. I have 6 of these machines and I would like to get more holders but would like them to all be the same.
I found one website that had pictures of them but they wont return my emails see the link below
