I’m using Kool Mist for just about everything and I’ve been happy with it. It’s cheap, works well and doesn’t leave a huge mess. If I could run a proper flood coolant system I would, but due to being an open machine I can’t.

The bath is super easy, it’s just a bit more involved to set up. If I had an enclosed machine, I’d be inclined to run it with flood coolant every time, but I’d be worried about that getting into the machine. Getting that powder on your ways is fucking terrible and can destroy a machine pretty quickly if you’re not cleaning everything after each time you cut CF. I think the extra time for setup is worth it, but I’m not running production or having to hold super tight tolerances in most cases.

I’ve mainly been doing 3mm CF using 1/8” end mills. I’m pretty sure I’m using what you’re describing. I get the coated carbide diamond pattern end mills from Amazon. (HQMaster 10Pcs CNC Rotary Burrs Set End Mill Engraving Bits PCB Milling Bits 1/8'' Shank Titanium Coated Tungsten Steel Corn Milling Cutter Tool for SMT Mold Plastic Fiber Wood Carbon Insulation Board https://www.amazon.com/dp/B07G3Z5FJ7/ref=cm_sw_r_cp_api_i_G7YTCbMCMRXQ1). They’re incredibly cheap, last pretty long and give a surprisingly good finish. It doesn’t feel right that they work so well.

Here’s the part I cut last night. I’m very happy with those end mills. Especially considering I was using a 400 watt spindle slapped onto the Fryer’s head ahah.
