Hello Tom
I too would like to thank you for putting me straight on cutting fiber cement boards with the TS 55 [thumbs up]
When I first purchased the TS 55 going back quite a while, I told the store guy what I was proposing to do and he told me in no uncertain terms that it was a big no no to cut such boards. The boards that I hope to finally use in our loft conversion one day is Fermacell, I don't know if you've any experience of these particular boards Tom? The store guy told me about the Festool AXT 50 LA-Plus and that is what I would need to undertake that task.
Having surfed left right and centre these last few days I have seen your posts on other sites also, stating the same that the TS 55 is up to the task and that Festool supply a PCD saw blade specifically for the TS 55.
It seems the Festool PCD saw blade (F28516) is widely available in Australia even at this time:

I asked a well known Festool supplier late yesterday afternoon and he had never heard of it or price it up as his Festool price list only recognized six digit numbers, and would not accept a part number beginning with a letter. It was too late to try Festool UK to see if it is for sale here.
I have ordered the additional dust cover (491750) which should increase dust extraction. If I was to get the Festool PCD blade I cannot see how I would be doing anything detrimental to hamper my warranty....... If I end up using a CMT fiber cement blade, I guess I'll have to just take a chance with the warranty.
Interesting to see that the Festool Australia site sells the CMT blades (but does give the warranty warning):

If I hadn't have seen your posts I would still be pondering buying this little used Festool AXT 50 LA-Plus Building materials saw 561442 from the German eBay site:

As it stands and from what I have learned from you the dust cover and a PCD saw blade is all I need, so again THANK YOU [smile]
