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...
