Could I use dremel or rotozip bits to do CNC work? The problem I am finding is when I plan a job in Fusion it will take forever to mill a pocket in my spoil board and for some reason I get collisions like mad even under different strategies. I find the length of the other bits a bit longer and relieves the problem.
I have used them before, but they are no where near the quality of buying the right tool for the job… I also use standard wood working bits you would use in a hand router and they work pretty darn good and are reasonably priced for their size and most are carbide tipped… Dremil and rotozip tools are typically Made from High speed steel (HSS)
Try them, I used a 1/8" spiral up bit because the 1/8" that came with the 3040 was not long enough to do .75" MDF. This is 18" x 36 when mounted. I found a lot of cheap bits work fine and when you break an expensive one it hurts. I keep experimenting so breaking a lot of expensive bits is not an option. YMMV.

Nice work!
I bought a couple of different bits. And I also bought an Irwin router bit that 1/4 shank. I was thinking about trying to use it to level a spot on the spoil board.
Yup. I just milled the pocket in my waste board with a 2mm dremel end mill. I ended up using plunge depth of 1mm and feed rates of 500,500,40. I wrote a tiny php script to generate the gcode sweep pattern. Easily replicable to JavaScript or whatever. If you let me have the dimensions i can post the gcode here or provide the php/JavaScript etc.
Why would you use such a small bit to flatten your spoil board? It’s going to take ages. Is it to do with issues traming the head? That’s the only reason I can think of.
