I bought some festool blades today hoping to get a perfectly square cut in thick material. I don't actually have plans to cut material this thick for any of my jobs, but you guys understand...gotta see if this thing is a jigsaw or a bandsaw. So I went back to the same Bosch blade (T345XF) that I previously posted in the P1cc vs Carvex 420 EBQ thread where I made cuts comparing the P1cc to my Bosch jigsaw. The Festool blade that I used today is the S 145/4 FSG. I had to do the test several times because I was shocked by the results. In anticipation of something impressive I had my daughter taking video. The Festool blade was horrible. It bounced all over even with both hands on the saw and after about 5 inches the P1cc stopped, not because of lack of power, something with the electronic protection. This was really surprising to me but it was more surprising how smooth AND square the Bosch blade cut. Absolutely no hint of wanting to stop. I could have ripped all the way down a 12' long 4x4 post without trouble or excessive heat. Craziest of all is that these cuts were very curvy and perfectly square, as you will see from a bunch of pictures. In my first tests, in the previous thread, I had apparently failed to turn the oscillation function on. That is the only difference I can think of because this time they were perfectly square. No W1 Cunex blade needed. I have 18 pictures so I hope it isn't annoying to anyone. These three pics are all of cuts made using the Bosch blade.

Picture #1 is the same cut with the off cut done with the Bosch blade. Pic#2 bottom is same Bosch piece and the top is the cut with the Festool blade. Saw settings all identical. Pic #3 As far as I made it with the Festool blade before the electronics of the saw locked it up. This was the second try as the first try also seized up. I am still a bit bummed out. I was looking forward to having a good blade of this amazing length for use in the P1cc. Bosch blade was effortless in all cuts. Maybe all the bad publicity about the Carvex has more to do with the blades being bad than the saw. Notice in the middle picture how rough the top cut is compared to the bottom. The look of the rough cut explains what the saw felt like while making the cut too.

No sanding. Again, I wish the Festool blade was good. It would come in handy because of the length. In conclusion I am wondering if the thickness of the blade is actually a problem. I am thinking that this is why Mafell doesn't make the cunex W1 blades in a longer version. It makes sense that the engineering of a jigsaw has to be done like the P1cc. I think if the saw was any more powerful it would possibly create problem with breaking blades on knots etc, less powerful would cause the cut quality to be degraded. On this last really curvy cut it was not 100% square but was really close to it. I think it could be made 100% square with even a little care...I was going fast with no focus or planning towards a perfect result. P1cc Perfection.

Thats amazing! Those cuts are very square with the Bosch blade. Makes me far more interested now that I see the true possibilities.
I'm surprised at the result with the Festool blade. One would expect a better outcome.

ya I know I feel a strong urge to reconsider purchasing the P1cc

Those are impressive results. For what its worth, Bosch does also make some long blades that are .07 inches thick -- one of them is over 10 inches thick. Look for the blades that end in a "DP" -- stands for precision for parallel cutting. I suspect that the thicker Carvex blades did not do well on curves because they were designed for straight cutting. I suspect the thickness impeded this ability. It is good to hear that you got such good results from the Bosch blade you did try...the cuts look great!
Can you try a parallel rip and see if the results vary with the Festool blade and the Bosch? Also, Festool makes the FS style blade -- another thick blade without a set for smoother cuts. Bosch has an identical tooth pattern in the T1044DP series. I have had great results with my Festool blades in both Bosch and Festool jigsaws and mediocre results with Bosch blades in my Bosch saw (OK results in Festool).
This is a great thread and thanks for the updated information...

Good point on blade thickness causing deflection, the CUNEX blades are tapered in the back end to prevent just that. Still really nice cutting results with the bosch blades

This is a great thread and thanks for the updated information... The festool blade did a little bit better when ripping but not excellent still. It was still somewhat jumpy. Thats kinda funny, I never even considered that a jigsaw blade would be designed for ripping; such an odd use for a jigsaw when circular saws exist in so many varieties. I was just thinking the thickness of the Festool blade was so it would stay straight in curves. I bought some other Festool blades that I haven't tried yet. I am sure they are good blades and it is totally possible that I was using this one for the wrong use. I never looked up any information on what its use should be, it just looked like a wood one to me so I got all excited and started plowing through a big fat post with it:) I like to experiment with these things. I'll try some of the FS blades when I come across some.

7, I'm assuming that the Bosch blade is the Progressor? Did you compare that to the Cunex blade? Also, what did you have the oscillation set to? Thanks.

Yes it is Progressor. It is the T345XF blade. On the length of the blade it says "progressor for All Purpose". The reason I was so surprised by the cut result was that this is a very standard, non specialized blade.
The orbital on the saw was turned on all the way.
I didn't compare it to the Cunex blade. The Cunex W1 blade isn't long enough to go through a 4x4 post. Luckily no real reason for me to compare because the cut couldn't be more square than perfectly square anyway. If I am remembering correctly the specific Bosch blades I used were purchased at Home Depot in a 3 pack for about 7 or 8 dollars. I had these Bosch blades in the case with my old Bosch jigsaw before even purchasing the Mafell saw. They never stood out as anything special until these cuts with the P1cc.
