Hi Karl,

I am certainly no expert on cutters, just an ordinary user. I do earn a bit of money cutting stuff, mainly aluminium but also wood, MDF and plastics. I bought this single flute cutter because of its "good looks" and when I actually tried it (many weeks later) I was stunned about its performance.
As I take a lot of knowledge from the forum I thought I give a bit of info back as I am sure that some will profit using these cutters. As mentioned, I now can easily cut aluminium on my home made router as before, with whatever I tried, the results were not impressive.
You will have to try one for your application to see how it works. I made a nice holder for my collets in a "hardish" Australian timber, some kind of a redwood. And it worked fantastic.

I buy these direct in China as I visit there quite often

but am not sure if they sell direct to outside China or what is the minimum quantity. There are also a few shops with the product on EBay and yes, there are high quality ones for a lot more money too. I regard the cheap ones as throw away's but never actually did throw one away yet. So far I made around 200 liters of chips with just a 4mm and a 6mm one.

I published the video's as I realized that I make big words and needed to back it up. I will make another one cutting off a 1/2" aluminium plate with a 6mm cutter in one go at 100mm/min (4"/min). All I can say is that I could not do this with any other cutter I have tried and I paid top dollars for famous brands. Not even close. Just give them a go and I am confident it will work just fine or you can use it for something else.
