Bahco ProfCut Insulation Saw - Waved Toothing - low friction and creates less sawdust - (VCI) that will protect the saw from corrosion

This cuts through even soft woolly insulation like hemp - sped up installation!

Not a conventional saw but a long handled serrated knife. Cuts insulation beautifully with hardly any dust. If insulation is a bit tight between wooden battens / rafters etc then use a sawing motion in between and you’ll get a perfect fit.I found it useful to score the line with a Stanley knife before cutting.If in doubt - buy one!

This saw was purchased to use during the conversion of my roof to a warm roof design. This meant cutting a large number of Kingspan / Celotex type boards to fit between and under the sloping rafters (including a lot of bloomin awkward shapes and angles...)Normally I would use a conventional fine tooth saw for this type of job but for a relatively small outlay I thought it worth trying this - especially due to the promises of reducing the dust when cutting in a confined space which can be a nasty hazard.Firstly - whilst the descriptions of 'new waved toothing' may make for a good sales pitch what this really means is 'it is a large kitchen knife blade with a serated edge'. Nothing worse for that, but hopefully it helps you know what you are getting!After a bit (well, a lot) of trial and error I found that:- This saw is brilliant at carefully cutting angled pieces in any thickness (including 45 degree cuts in 100mm thick board)- The thinner the board you are using the more successful you are likely to be with long straight cuts. For the thicker boards I found the thin blade wanders far too much and I went back to a conventional saw and got much better results.- You need to keep the blade sharp. I bought the Bahco original one with the saw, Bahco SHARPINS Insulation Saw Sharpener but this is just a standard knife sharpener in an expensive piece of plastic; save yourself a few pounds and just use a normal one.- When the blade is sharp you can finely adjust your cuts by shaving the edges of the boards with much less dust than a normal saw blade generates.- For final fitting of boards between rafters I found it easier to run a conventional saw down the edge. This makes for a lot of dust but on balance it made for a quicker and easier job.Overall, this is a very useful additional tool if you have insulation work to do, but I would not suggest it as a complete replacement for a conventional fine blade saw

This item is ok for cutting celotex upto 100 mm thick but struggles to remain straight without flexing on 150mm thick celotex or equivalents.

Not impressed. The saw arrived with a poorly finished edge,complete with a wire left from the grinding. This was the same across two saws, as I recieved the first with a smashed handle - it was poorly packed by Amazon. I was issued a refund and replacement for the damaged saw. I had expected this to be honed to a razor edge as per other cutters I have used. Pavatex supply an excellent knife, for example. The saw now performs well with a hone, this was a hassle I didn't want to waste time with. But, I have a homemade knife edge insulatuon saw, ground out of an old hand saw which performs better, and with less ripples in the edge of the homemade tool, it is easier to resharpen. If you can make your own, don't bother buying this.

Great saw for PIR insulation although probably better for the thinner stuff. I used it for cutting 90mm insulation and it did tend to bind up a bit but pretty much no dust kicked up unlike a normal wood saw. I think this would be excellent for 50mm or smaller insulation but cutting a full length 90mm board wasn’t without effort.

Cuts easily & cleanly. Great value for insulation job.

I had high hopes for this saw. Facing having to cut 18 70mm thick kingspan insulation boards the promise of a saw which would not produce dust was very appealing. Unfortunately it is impossible to make a long cut without the saw drifting off line.I noticed a couple of the reviews indicated this could be a problem but could be solved by marking each cut with a sharp utility knife. I tried this and it still didn't help. I could keep the saw blade on line on the front face of the board but the blade is so flexible that after a cut of only 12" length the blade had drifted off line by 1 inch on the rear side of the board. At £35 per board you can't afford to waste them with inaccurate cuts. I've reverted to a standard stiff bladed saw and put a dust mask on.The concept of this saw is good but the blade needs to be far less flexible as it simply doesn't work in its current design.A total disappointment
