Hi Kevin, it has a much higher rake angle at the cutting edge and is therefore sharper leaving a better finish, but the being sharper it breaks down faster in steel and doesn’t last very long, plus you can only take light cuts. I found this out through experimentation.

Hi Steffen, I think I would have to go back to the drawing board and redesign the part. Would it be possible to make an adapter perhaps? Or machine the 3D print to fit?

It should be doable using suitable 3D cad software, but I don’t have much experience of manipulating STL files

Thanks Steffen! Good luck with it and let me know how you get on!
