PCBs ... so more like cheese on toast.
I've used 0.8mm on the router with aluminium - it didn't break!

Using a spiral toolpath works well for that.

as has been mentioned before, you will end up with a small dome in the center. These cutters plunge much easier than two flute cutters.

My 6mm single flute is actually 5.95mm. With the right data the cutting is very accurate.

I used 1mm two flute cutters in the past on aluminium and acrylic with very little success. But the single flute 1mm cutter did a fine job and is still in one piece after about 3 hours work in aluminium.

I accidently chipped one of the single flute cutters, but it turns out they are easy to regrind ... works just as well as new now. I was thinking I should buy some more in case these break... but it looks like they're immortal.

Just tried the same cutter on plywood, 14000rpm, 2800mm/min (so quite a high chipload) with 4mm depth of cut on spiral toolpaths. The cutter was quiet, left a good finish on the sides (but ripped the top not surprisingly) and did not heat up much so I'm sure it will go faster!

I did I video which I'll upload at some point.

Strictly speaking they leave a small right circular cone in the center.

In the past I used two flute HSS and carbide cutters for my aluminium work. On my Syil X4 usually I did cut 2mm deep at between 5 to 8"/min (120 to 200mm/min).
With these single flute carbide cutters I can now cut 6mm (1/4") deep in one go. On my bigger X6 I can cut 1/2" in one go @ 100mm/min (4"/min). Plunging is a breeze.

Now, with these single flute carbide cutters I can cut much more efficient. And on my home made router I can now take 3mm (1/8") deep cuts in aluminium without problems. No more melting of acrylic either and 16mm cuts in MDF are a breeze... .
I uploaded two video's to YouTube

Compare these to a video I made some months ago and you will see why I am so happy. To add to the fun is the price of these single flute cutters. Cheap as chips.

Originally I made these video's for my machine supplier, personally I have no connection to Syil or to Titan. i also have a Sieg KX3 (excellent small mill) and a 3'x3 1/2' table router I made myself as well as a 5'x12' Forfun router from China. Yep, I am an addict...
