Hi All
Years ago I bought (for a company not me) a load of sheet cutters, they were a three piece affair, with a male and female cutter and a bolt. You drilled the centre of the hole and put one part of the punch either side, ran the bolt through (probably a machine screw really) and tightened it all up, cutting a disk from the metal and leaving it nice and flat.
What were they called? Q-somthing I think, and does anyone have access to them or similar, and can I borrow one of 40mm or so? - I have 4 holes to cut.
Thanks
R
