When drilling holes in metal consumer units to drop cables into (SWA) I need a set of die cutters and mag tray to catch the swarf I had a set yonks ago but long gone, I have project in the offing where I need to cut several holes for 1.5mm 4core SWA I have tried google but cant find what I need, basically there is a central bore and a two part cutter one inside one out a hole is punched for the certre and the other two parts are wound together with a ratchet ring spanner the hole is cut with very little swarf, any idas peeps, its very similar to what garages used years ago to fit arials to car wings
