CNC Shark Forum

After seeing some drag bit projects on this and other forums, I was excited to try some myself. Turns out the bits themselves are cheap (~$10) while the mount/holder you need to get going is expensive ($150+). So I made my own. It's about as simple as it looks. I did a full write up with more pictures and a resulting project here:

That is cool. I haven't tried any drag bit work myself. Where do you buy the bits?

From eBay or AliExpress. They'll run you a little less than $10 apiece. Be sure to indicate the angle you want. I'd suggest 60 or 90 degrees.
