I like the occasional sheetmetal job, and with my Magnabend it’s fun and relatively easy. What I lack is a way to quickly and easily lop 8′ x 4′ sheetmetal into usable pieces.
Ideally, I’d have a guillotine, but I don’t have the space (or can’t justify it) for a tool that will only be used once in a blue moon.
So I’ve tried cut-off wheels on grinders, abrasive wheels fitted to my circular saw and hand shears (and probably others) but I’ve never liked the results.
That was the easy part. The expensive part was getting one to Australia. The blade was about $40 but the shipping from USA was going to double that, making it a pretty expensive experiment.
Luckily a mate who works in the US offered to bring some stuff over on a trip back here so I got it shipped to his place before he left:
Well, all I can say is: the shit works. Pics of my first cuts in 0.5mm cold rolled steel using my big old heavy Dewalt 7-1/4″ circular saw:
Negligible burrs, straight edges (and that was without using a straight edge guide or fence), quick and clean. I think they understate the dust aspect a little – that 1/8″ saw blade kerf material gets converted into dust no different to an abrasive wheel – except it isn’t hot.
I will also admit this is the first time I’ve taken to wearing a full face shield as well as safety glasses. gloves and ear muffs due to the sharp and high speed dust particles this baby generates:
But – if you don’t have a guillotine – get one of these blades!
