During the first pass, a lot of “waste” stays on the surface. In a second pass, the sled is not completely to surface… I’ve stopped, sanded of the waste and restarted the process
I’ve done a circle, counterclockwise milling. However, in the going down part, the sled is coming up on the deeper cuts. On the left side:
I’m not sure
They are very sharp, so I think they clean up the sides when you reach a certain depth.
I will cut the actual part with this bit. Tomorrow they will normally deliver the normal single flute spiral bits. I cut the next part with that one and compare.
Edit:
This is what it’s supposed to do:
3-piece drilling set with titanium coating.
For drilling, filing and milling wood, plastic and aluminum.
Use the drill part to drill the start hole and use the tooth part for milling and filing the material.
Drill sizes: 3mm, 6mm and 8mm.
(Translation of Dutch).
So actually they should work quite well. And only cost 6,99 Euro for the set without delivery costs.
That almost looks like a drill bit (almost similar to a drill & tap bit (my edit after your edit - sounds like they are designed for use in an electric hand drill)) with the way the nose is shaped. If it’s a milling bit designed for metal than the 12000 rpm is going to be way too fast for wood IMUO (In My Uneducated Opinion). Those bumps and ridges are probably causing some tear out.
Hope you you have better luck with the single flutes. The logo looks good otherwise.
I can’t hardly wait for my Maslow to arrive. (Hopefully getting shipped this week - fingers, toes, arms and legs crossed for luck)
that bit is not designed for a router. I have a bit like that it is made for widening out holes, and does poorly at that.
if you have amazon prime you can get 6mm bits for $3 each in packs of ten $30 total
I had similar problem using single flut “round” end bit, i found it would lift the sled and wobble on the first pass then some what settle after that. I swapped to flat end single flute once they arrived in post and the difference was outstanding. I think the right bit will make all the difference for you
Edit, 2 flute bit. On that note has anyone used this type of bit?
It looks like some sort of combo drilling/roughing end mill for cutting metal. Literally, rough and fast. I think, being a novice metal worker myself, it is to make a less than perfect hole to make a friction joint. I could be completely off base.

Got those, they are crap
I order my router bits on https://www.ecotools.nl , real cheap and good enough for now. And they get here faster then aliexpress.
I use this one if it’s all outside lines, so the diameter doesn’t matter.
And this one for the finer work, it doesn’t have a cutter at the bottom, but the specific cutting part is wide enough to not let that be a problem
Just came in today and mounted them directly. The difference is amazing.
Not a single wobble, nice finish.
The other ones I posted above gave a lot of wobble and the finish of the circle… Let’s say it has a hand-made touch (unfortunately it is machine made ).
I will also try the ones proposed by Dag and compare. For pocket milling they will be better than the spiral ones, I guess.
