Regarding the TKS 80, I saw it demonstrated at three different tool fair including the Festool roadshow.
The public seemed very taken with it generally but, on all three occasions, and also in a dealers, I heard people moaning about the plastic parts, and whether it was a true portable saw or not.
One of the Festool reps, might have been Phil but, can’t be sure, mentioned it was a prototype and may go through some changes, before final release.
As Cheese mentioned Delrin or PTFE may have been a better choice of material, instead of plastic. I guess if this becomes an issue, they’ll modify some part.
Not a fan of plastic in tools, or rather the over use of it but, I fully understand it’s benefits, and the tech that goes into it. Even some of my favourite tools include a lot of plastic.
I remember owning an all metal table saw many years ago, it was superb but, got stolen.
When I bought the replacement, I was a bit upset to see how much plastic was used.
The top was alloy but, the main body, knobs and levers all plastic.
That saw is still in use on site 24 year later, it’s been a superb tool.
So I misjudged it’s durability.
