    Be prepared to break a few cutters.
    I'm with Clive on this one. 3mm tools are cheap enough so keep the 1mm depth of cut (or maybe up it to 1.5mm, 50% of the tool diameter) and crank up the linear speed in steps until you break the tool. If you've been running at such low speeds up to now you will be pleasantly surprised at how fast you'll be able to cut even if your machine is not very rigid. I'd be fairly confident that you can cut at up to 3m/min (50mm/sec) in MDF with no problems. Just be aware that MDF dust is nasty stuff so a mask and dust extraction/vacuum cleaner are essential.
