Using paper to cut through plastic, acrylic, and wood.

Interesting video of the capabilities of a small paper disc attached to a rotary tool.

Thumbs up

The power of mechanical friction , generating heat to cut the parts by locally melting the part , weakening it and then separating

I use a Dremel for many things.
But, I never would have thought of using a paper disk with it.

Wasn't convinced until I made a disk and tried it on my Dremel. Chomps through 1mm card without a problem. I found you could get very straight cuts by cutting along a ruler placed over the card.

I think with a bit of practice it would be easier to cut 1mm card with the paper disk than the snap off blade knife I use. The smell is a bit of an issue - cremated paper.

Regards

Charlie

Not only do paper disks cut efficiently but they can also be used to polish the edge of a scalpel to sharpen it. Just got to remember to have the direction of motion towards the edge otherwise the scalpel will cut the disk,

I'm going to have to give this a try. What a great idea. What speed setting do you use for this? Thank you very much. wc
