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.Quote:

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...
i tried to watch the first two video's but they are private ??
so I can't view them

You set the video to private and can not view it.
sorry for that, have no idea really about this "modern stuff" but managed to change it. Hope you enjoy.
