I've used jigsaw (bosch 150 model) to cut 1mm steel. Turn the oscillating action off(or it can mean returning saw to Bosch - just don't ask!).Works well. You must support the cut near the blade. I found putting hardboard over the top of the sheet (clamped) and cutting through both worked OK. Fine blade is needed and turn the speed down. Can cut quite good curves upto about 70mm radius but need a thin (cutting edge to blade back blade) to do that and they're fragile.

Vibration is a problem and tingling hands afterwards!

Have got some 1mm angle grinder blades but not used in anger yet. I second the comments re nibblers-you also need quite a good air supply for the compressor ones-my little compressor just could not cope. Thought of getting a bigger compressor but then got really knarked about the half moon swarf everywhere so switched to using the jigsaw and am happy with that.

"Seems that I owe you something Roger, so here it is..."

Thanks for that, Hans, I've been following this thread with interest. When I first looked at the link you provided I was surprised by the idea of using such a large tooth geometry for cutting thin sheet, hence my questions. However, as you have shown, there doesn't appear to be any problem at all - the edge of that piece of angle appears very clean, with no distortion. Can you tell me how close the cut is to the corner of the angle (i.e. how much support the side being cut was getting from the fold in the metal), and secondly, how was the piece held while being cut? Was the side with the holes simply clamped in a vice, or did you use any backing sheet (particle board, etc), and so on?

I had a look for anything similar at the local Bunnings store a few days ago, but while the blades that I saw all had a similar geometry, they were mostly larger, and only rated for cutting masonry or ceramic tiles, etc. I will need to look further, but I'm sure there will be something similar to the Kaindl product, although the Kaindl guard also looks fairly substantial.

Roger
