They are definitely tough.
After fixing our gas oven, which involved drilling some holes and using a pop rivet gun, I accidentally left my 12v DeWalt cordless drill sitting on the broiler rack and forgot about it.
Later on, at dinner time, my wife flips the oven on, and after 5 minutes or so, we start smelling burning plastic.
I’d basically broiled my drill for 5 minutes on high. I took it out, cooled it off, and to my great surprise, everything still works fine, despite being somewhat melted and burned looking on one side.
