Bosch 3x PRO Fibre Insulation Precise T1013AWP Jigsaw Blade (for Mineral Wool, Mineral Wool, Length 250 mm, Professional Accessory Jigsaw)

Absolute game changer for cutting insulation board, no dust, no mess and clean cuts.

As a DIY user, I had been told by others that cutting the thicker types of Celotex foam can be messy and tricky, especially without the right tools. I read various forums plus watched several videos and decided that these Bosch blades were the best option, as I already had an electric jigsaw. I ordered two packs believing them to contain a single blade in each, but in fact there were three blades in each pack.My first attempt was disappointing - I found that trying to cut along a marked straight line was much trickier than I imagined. The moment the blade went even slightly off line, because of the length and depth of the blade, steering it back to the line resulted in the bottom of the blade waving about hugely on the lower side of the 90mm Celotex I was cutting. An unacceptably wavy cut ensued...Then I hit on the solution and can suggest that if possible anyone using these blades considers doing the same:1) Use an angle grinder to cut the blade to the correct length for the job, so that it is about 1cm longer than the thickness of the foam when the blade is at its least depth on each cutting stroke.2) I laid out and screwed down 4 lengths of 70mm x50mm timber to my work benches, two outer ones to support the sheets and the two straight edged inner ones a few mm (4mm ish) apart to act as a guide. I then clamped each sheet down with the cutting line above the gap in the two batten’s. In this way, the bottom of the blade could never wander off by more than a couple of mm or so and I ended up with really straight, long cuts along the whole length of the foam.Accurate cutting made all the difference to what can be a very tedious job, and these Bosch blades kept the mess to a minimum, unlike my earlier attempts with a fine toothed hand saw.Thoroughly recommended, a great product if used with care.

These blades avoid all the micro plastic mess of other methods of cutting insulation. They are very good. However I find them slightly too bendy, meaning they often flex to one side as you cut. This in turn drags the tool off course and simple corrections just add more side load. Once you learn to push it away from the line you are cutting along to make it straighten (counter intuitive!) it does ok, but it’s annoying when one side is cut as desired but the other side is either 10mm too narrow (big gap), or worse still, too big to fit (no chance of trimming the excess with such a bendy blade). Needs to be that bit stiffer for 5*

I bought these blades because they were recommended for cutting polystyrene insulation panels in several forums and YT videos.They do indeed work excellently for that purpose with a cut that looks as clean as that of the panel's original edges.One thing I've not read in any review here is that the blades are wider (not thicker) than the standard jigsaw blades you usually buy. They fit my Bosch PST 800 PEL perfectly but I noticed that because of their width the roller guide the saw blade rests on holds it at a slight backwards angle.Initially I though I'd mounted it incorrectly but no it is definitely being held by the roller a few degrees off vertical so that the cutting is done at a slight angle ie. the bottom edge is being cut first.I don't know if this is why it cuts this type of material so cleanly but I thought it worth mentioning. It is probably a combination of that with the scalloped cutting edge but more to do with the latter.It is difficult to think of any alternative method that will cut such paneling as well as a jig-saw fitted with these blades.

These completely changed my view of PIR insulation.Brilliant. Straight deep cutting no dust.

The media could not be loaded. I'm in the middle of a garage conversion for a client and have loads of 100mm PIR to cut. Thought I'd give these a go to save cutting it all by hand. So good! Virtually dust free, perfect clean cuts. The blade did want to track a bit at the bottom of the cut but you quickly learn tricks to cut well. Keep the speed of the jigsaw high but move slowly and the blade has time to stay straight. I used the Makita 18v jigsaw and it cut easily. I cut against a piece of timber to keep the cuts straight and spiked a couple of screws through the timber to stop it slipping. I also found it much better to cut the board width ways to reduce the blade tracking and keep the pieces more manageable. It also cuts whole rolls of loft insulation with ease. Worth every penny. Imagine cutting that lot by hand!

I bought these after watchung a youtube video, where they seemed perfect for cutting 100mm celotex. I was only cutting 25mm but thought I would give them a go as I had 40 sheets to cut. From the first sheet the blade wanted to pull to one side an no adjustment would correct it. Ended up using a guide and cut a sheet, as in the video no dust and a clean cut. So I tried 3 sheets next (75mm) seemed to go ok using the guide until I the middle of a 1.2m sheet. I stopped to check and realised the blad had pulled off at an angle underneth by 25-30mm. I then had to repair, tape and re cut the 3 sheets by hand. Blade went back in the packet and returned for a refund. and I cut the other 38 sheets with a knife. Useless in my opinion and I was using a Bosch jigsaw. Got money back and only my time wasted

Used for 100mm insulation, does cut without any mess, but the heat generated makes the blade bend, so you don't get a straight cut.

I didn't know that this blade even existed, but Amazon had it. Now it is in stock for them I think. I am on my second set of these blades and they are almost magical how they cut multiple sheets of double and triple corrugated cardboard. I am most comfortable with about 5 sheets at one time. The patterns I am cutting out can get complicated, and at about 5 sheets they stay on track without swaying off line at the bottom of the stack. Thanks

Works great for cutting styrofoam.

Es muy util, especialmente para cortes curvos.

Bladet ser i princip ut som en brödkniv. Syftet är att skära i mjuka material, i mitt fall kallskum till dynor. Detta arbete fungerar bladet perfekt till, därför att man inte bara kan skära raka snitt, utan med sticksåg skär man jämna, rena kurvor. Bladet tillåter också att man justerar nära kanten på skumplasten, givetvis med begränsningen att skummet man skär inte är alltför mjukt.

Works in 10cm PIR but you need:PowerGood support allong the cutFirm pressure downGuidance is recommended500 watts was to little. 780w is going awesome
