My drag knife tool project

[ZbLaB]

I decided to share my project of drag knife tool - everyone will be able to make his own.



It increases functionality of (almost) every CNC router. It can be use for cutting veneers, paperboards, gasket boards, magnetic and vinyl foils, etc. - materials that are thick (less, than 4-5 mm) and hard to cutting by milling.

Very important is solid fixing of material, flat table of router and good quality of blades.

ZbLaB,

Nice work, thank you for posting the files.

One question: What is the purpose of the magnet?

Jeff...

Magnet just pulling blade before it will be fixed by tightening M5x8 screw. It is comfortable, but not absolutely necessary.

Nice, I'm going to have to try this out. Thank you for sharing!

I see that you aren't using bearings or a spring. You do rely on the bolt shaft swivel. I am curious if you tried letting the router or spindle handle the swivel by itself?
I would use one very little myself, but I have a project where I would be cutting vinyl and only cutting straight polylines. None are even connected. I could setup a jig to make these cuts by hand of course, but since we have CNC....
Making a small compact cutter is my goal. I will use the same Irwin Blue blades as everyone should. Fairly unbreakable, rugged and sharp.
