Routing track with CNC and 0.7 mm bit.

Post by kiklo » Wed 16. Sep 2020 16:01

A friend of mine has a small CNC router - but no small bits.
We decided to test with a small drill bit just to see what happened.

Of course it broke, you can see it bending.
Then he used the remains for a new test.
It did work if we did it slow enough. We will do more when I get proper routing bits.

What kind of material are you trying to cut?
The bit would not likely break if you were workling with Polyisocyanurate Foam Board Insulation or Extruded Polystyrene (XPS) Foam Board Insulation. Polyisocyanurate is quite rigid and very light weight. With the appropriate facing material, better than XPS for making a track in my opinion.
