I think amazon.co.uk sells them for less (shipped). But if you can give up 1mm of d.o.c. their 160mm blades are much less, not sure about kerf / plate thicknesses though. Has anyone here ever checked Key Blades mafell blade kerf / plate against the oem mafell (?)
And if you don't mind running a 165mm in your saw, and picking up 1.5mm extra d.o.c., the Bosch 'top precisions' are perhaps a more 'vetted' product but still less than the 162mm Key blade.

Key blades are excellent. Good value for money, extremely clean cut and hold an edge well. I think they are exactly the same kerf as mafell. Will check on Monday. They are fast becoming the go to for many of us here in the UK for lots of brands.
They are a good company too, they value feedback and actually listen to customers wants, their line up is improving all the time.

Ok guys, I'll take your word for it on these blades as I've just now ordered a twin pack of 24tooth to try out.
Reason being is I had to cut an oak kitchen worktop with the supplied 48t maffel blade that came with the MT55 and ended up burning the edges of the wood. In all honesty it struggled quite a bit, smoke blowing out everywhere and a couple of times cut out, but thats the electronics doing their job. I did try pushing it through the wood at differant speeds too but still struggled.
So just put it down to having the wrong amount of teeth. Anyone else ever experienced this?

The Festool Panther works well on the MT55, can't remember how many teeth, but not many!
I've ordered a good bundle of the Key blades to try for various saws I own, also a multi-tool set of blades. Should have them tomorrow...

For now, I've tried one Key balde, the 48 tooth Mafell replacement. Be cutting up some white melamine board using both Festool and Mafell rails. The cut is crisp and clean both sides with a first cut at 3mm, 2nd cut at 35mm for 19mm board. The off cut is perfect too.
My first concern when I received the blades was the painted finish, even right up to the arbor, it is not perfectly finished, a slight run mark in one place. If I put a straight edge to the finished cut, there are slight undulations. I'm not sure if the blade is not spinning perfectly true due to the paint causing the blade to sit slightly out of true. I need to clean this up back to the metal just around the arbor and see if it's better.
Otherwise a very good blade, exceptionally clean cuts - need to see how it lasts in the long run. I have others to try at some point.

... how has the Key held up? In a word, excellent. You know...I used the maffel 48T to cut a solid oak worktop 50mm and it struggled like hell, smoked out the place, yes it looked very unprofessional, but saying that, it may well have been too many teeth for a board that thick. Even doing shallow passes it still struggled...
I put in a 24T from Key blades and tried it on the same worktop, dude it was like a warm knife through butter. I've used it for other types of worktop and mdf and I'll be using Key blades from now on. Decend price too.
They also put me in touch with a blade sharpening company too, after burning out the maffel blade on the oak worktop - canaancarbides ltd, avarge prices but they do a good job.

Yes, expect a 24t rip blade to cut faster / easier than a 48t. If you were impressed by the 24t for your purposes try a 12t and you’ll wonder if you forgot to put a blade in at all. If the 24t plate had an anti kickback shoulder that could have also helped if the oak was pinching behind the blade (vs a 24t without). Or if it was an FTG that sometimes cuts a bit faster / easier too. The supplied mafell 48t ATB is for smooth cuts in most veneer ply sheet goods. Though I’ve cut 1” hardwoods without any issues. But if that was your selection for the 2” oak you would have wanted to push at a slow feed rate.

I need to send a load of blades in to be sharpened... in the meantime, the Key blades are not holding up, I've gone back to an old and badly-in-need-of-a-sharpen Mafell. I think for the price they are OK, I'll be keeping them for hidden work, I'll bring out the Mafell blades for finish work.

Of the various 24t blades I’ve tried for ‘general purpose’ cutting I’m probably going to stay with the 160 Tenryu’s for budget price/performance. As they wear they are then demoted to the abuse stack where they will be ruined quickly (finish nails, osb with grit in it etc.). They still perform well even with chipped teeth. The Makita’s I picked up have a weird clear coat on them and though the cuts have be fine I’m haven’t exactly warmed to them. I trust the Bosch top-precisions & Mafell blades all day long for the critical stuff. The analogy of paying more for Michelin truck tires because of how they last & perform, giving me the better value in the long run, comes to mind.

I have stocked up on blades this year and decided to change often and fit the right blade and stop "winging it" on site with "whatever blade is on the machine". Blade changes are faster than going over a rough edge, post cut...

Here’s a pic from today where it was great to throw in a beater blade to trim some sistered wall studs and cut drywall. The door on the mafell really makes the difference (to me). there are 3 of those stud slivers blocking dust port, one behind the other in photo. I kept checking the hose to find the loss in suction, though dust collection was still decent. Opening the door gave me a laugh.

Blade changes are faster than going over a rough edge, post cut... Couldn't agree more, doing the same with the MT55's, KSS40 and Erika - right blade for the right job.

Was brushing off saw after cutting some exterior mdf. Removed chip guard and noticed a blade mark. This means that at some point, prob before cutting mdf, I must have been doing something pretty rough with the saw and got the blade to deflect a full 5mm. You just don't think about blade deflection but it makes an impression both figuratively and literally to know it bent that much. (I do use 165's in my saw and also have a very small shallow 'retraction' score inside the stationary side of the upper blade enclosure. The clearance is fine but after a cut you release the plunge and it hits a polyurethane bumper/stopper. That impact absorption can allow blade to just barely/momentarily close the distance. But that's a self correcting issue).

Do the newer MT55 saws still have issues bevel cutting on the splinter guard?
