Unknown tools-#2 looks like a paint stirrer,#3 appears to be a jigsaw,and the last one is a "flycutter" holesaw.Nice set-would love to have one!!!Bet that saw would really cut when the device is hooked to my NSS m1 or my Tornado!Basically,all the tools shown to use with the turbo tool motor are just like those used with electric drills at that time.With this turbo tool,or electric drill you can have a complete toolkit to do many jobs.Too bad you can't get these anymore!!!Just be so cool to have and use!
