I have seen quite a few posts about cutting metals and certain plastics with wood router spindles. I got to thinking that what might be useful would be a very tiny torque converter like on a car except scaled down. Being a small fry I have no desire to create one from scratch so I went looking and found this

Its used on motorized skateboards. I was wondering if something like this might work to convert the 8000 rpms of a wood router spindle done to something more in line with machining aluminum.
Hope this is the right forum if not let me know and I will repost.
Hope to hear what everybody thinks.
