Currently the 3mm spiral carbide bit tends to tear the MDF tests upward.
My objective is to prefinish some wood (say, airbrushing TransFast dyes on Maple) and then CNC a QR code out of it.
What would be a good bit for this? I’m OK with paying for high quality stuff. (bonus: feed/speed tips to avoid burning the wood)

Above: MDF tests w/ black gesso. The cleaner ones were lightly sanded to remove fuzzies.
