To cut the Celotex floor insulation into joist gap panels, I bought some of these jigsaw blades which should be good for up to 100mm.

Now the jigsaw is not one of my favourite tools so I have never owned an expensive one due to the little use I make of it. What I am finding is go slightly off line and the blade bends out and it is almost impossible to get a perpendicular cut over 1.2m in 75mm Celotex. Some of the reviews mentioned this and I was wondering if the problem is down to the blade having no set therefore not cutting a proper kerf or is it down to the jigsaw?
