Thread: cutter for MDF

  1. #1
    I have bought a selection of router straight bits from toolstation, around a 1 a bit including delivery. I got these because i know i'm going to break some etc

    Would these be ok for cutting shapes, holes, raised lettering etc

    Try it and see, for 1 you can't really go wrong.
    The ones you linked to won't be able to do 3D profiles as you need a ball nose or rounded cutter for that. Unless you have 5-axis, or 4 in some cases.

  3. Deannos, the cutters you linked are ok but tent to squeal a bit, regardless of feeds and speeds, i have found this to be down to the rake of the carbide cutter in this case none, i would suggest you have a play with a few of those the move on and get the similar one made by trend, this has a slight positive rake and cuts a lot nicer.

    Yes, I should have mentioned that. Particularly for me the 6mm cutter squeals and breaks easily.
    Another option is the 6mm single flute carbide cutters I keep going on about... they can potentially cause a problem as they are 'upcut' (spirals upwards) so could lift the surface of the MDF but try it and see. It's worked fine for me, plywood was ok with them too.

  5. I put the premature breaking down to the cutter resonating at its critical frequency, keeping the cutter short as possible will help things a bit!
