Blimey, you're brave

OTOH maybe you are cutting cheese or these are in stub length :naughty:

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

what about plunge cuts of flat bottom hole ??

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.

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...

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.

Here's a video of the 6mm single flute on my router:

I think that was 1mm depth of cut... I now use a bit more at the same feedrate.

sweet

are you cutting dry ??

[Jonathan]

are you cutting dry ??

In that video yes I think so. Now I tend to put a bit of coolant in the slot after each pass as it helps, especially on a small part where the heat otherwise just builds up.

i find it a bit of a dilema when cutting small slots... adding coolant tend to make the chips stick in the slot so theres a lot of re-cutting of chips going on or cut dry and clear the chips with a bit of air

i cut acetal dry and use WD40 in alli like you say, a couple of dabs on each pass..... watching your vid has me thinking that it may be worth me trying to cut alli dry more aggressive than i do so the chips clear themselves and forgo the coolant, it might be interesting to see how long one of these cutters will last cutting alli dry

the voice in my head tells me it will all end in tears but without a bit of science i guess we would still be eating bananas
