So we bought this to make specific cuts in 62.5mm Celotex insulated plasterboard, where other tools couldn’t reach. It did the job well and was well worth having as an extra option.

So much better!

Never tried one before- just used an old saw!
WELL WORTH THE MONEY! Quick easy and far less mess!

I had some fairly standard cuts to do and ended up reverting to my handsaw, when cutting 100mm Kingspan. I think this tool would have suited me better if I had more complicated cuts. But nothing wrong with it.

Blunt and ineffective

Totally useless, wouldn’t cut custard!!. blunt, might a well use an old blade and sharpen the edges.

Not so sure.

I used it on 100mm PIR and the blade doesnt stay straight so the bottom of the cut was angled. Reverted to a handsaw. Yet to try it on other insulation types or thinner material

Great blade for insulation cutting

Really difficult to use on 100 mm PIR it’s nor sharp enough, and drift in the cut is hard to control better with a good saw but messy.

Very little dust

Rupert Bare Verified Purchase

Creates very little dust and after a little practice can give nice straight 90 deg cuts.

Great for DIYers IMO

Yorkshire Matt Verified Purchase

It's a nice idea but it doesn't cut that smooth and when added with the noise of a multi tool.
However, if you re not used to cutting PIR it will save strain on your arm.
I'm sticking with my hand blades for now.

Very good and dust free, but doesn't last 2 days

Available when expected and as described. My multitool broke after I started using the blade, but this may not be the cause.

Very sharp and ideal for PIR insulation

Bought to trim PIR insulation and it wokred a treat. One issue I found was it can be tricky to keep at 90 degrees to the edge.

Dangerous

The blade delaminated and flew across the room the first time the multi-tool was switched on. No problem with Toolstation though who offered refund or replacement without question.

The blade broke after only cutting 3 times, very dusty while cutting. The idea of the blade is good, but i went back to using a hand saw.

Excellent tool. Does exactly what it should with the minimum of mess. Much better than a jab saw for cutting foam board.

Smart insulation blade….not very smart

Not sure if I got a dud one , but I was expecting similar to the Bosch multi material jigsaw blades that are brilliant…this in not! Has no edge on it - you can saw it across your fingers and it certainly wouldn’t break the skin however hard you tried. Didn’t have time or desire to take it back so I put an edge on it with a diamond stone - then it sort of cuts PIR but not really! Utterly useless, avoid

Not good

Bought this blade to make cuts in plasterboard and Celotex ready for installing electrical boxes in new extension and it made light work of the whole thing.
