To many dickheads man. I know if I put these on there some asshole will copy my stuff. I'm not really looking to make these for sale. They are just fun. Yes, friction fit for these. Might get into some threads later on.
Bought a Foredom. The internet said it was next level to a Dremel. More torque, better quality, blah blah blah.
Here is the single reason the Dremel kicks the living shit out of the Foredom. Don't even know about quality and torque, couldn't get past the fundamental user interface (<-nerd talk).
Below are pics of the hand tools for the flex shaft. The Dremel is skinny and a little thicker than a Sharpie. Contoured to fit the hand like a pen. The Foredom is a giant marker contoured to shove up the ass of the moron who designed it.
It's a tool for a "tool" should be perfect for you.
