No, most of it was perfectly preserved.
But now that I think about it, they were fond of more rudimentary woodworking tools like the adze, chisels, and reamers (holdovers from Neolithic times), despite having the capability for better tools like brace & bit or wood lathe. The adze in particular was used in their "opening of the mouth" ceremony - they really liked it a lot.
You can see Egyptian woodwork with dovetail joints alongside chairs with rawhide lashings from the same period.
The opening of the mouth was conducted using a angled iron or steel tool (W. Budge: Book of the Dead). Yes, he used the word: steel. I have a more modern translation which I have not read which may use a different word.
