I've had good luck with Ebay & AliExpress. Mainly Ebay sometimes they are one & the same. But its not a delivered tomorrow type thing if you're in a rush, but I'd guess 2-3 weeks has been my average.

If you feel you want to specify a brand (and you believe it actually IS that brand) you can sub filter with checkbox. The first 3 have been good from my experience.
The main thing is what do you want to turn, mild steel, aluminum, stainless....
Personally I like uncoated & sharper radius for aluminum. Some recent ones I got for stainless had a sharper nose than the usual offerings. Some sort of mystical magical coating which I didn't really care about or pay attention to. But they actually cut mild steel better than my previous gold go-tos. I can find the specific purchase if you're interested. Personally I think it pays to experiment a little. Our machines are typically not turning or feeding at cnc speeds which is where these come from.

Those are TCMT unless you mean that seller maybe?
Oooops missed that detail. Mine are triangular. Seller might have CCMT as well? Your $7/10 find is amazing.
Do you have a seller for those?

I got to both ends of the spectrum. for nondemanding things like aluminum and brass I use Bangood.
For everything else I pay the price and go Kinnemetal. I find it is really worth it for me, especially when cutting 316 or 4140. I extend the life of my good inserts using a diamond file, I get 2 or 3 touch ups before they're done.

My Bangood inserts seem to crumble at the sight of 1018. They do ok in aluminum and soft stuff like cream cheese though

I've had good results with banggood inserts, but I treat them like they are fragile - as I said brass and aluminum.
I've moved away from discount inserts because I've had very bad luck - broken inserts, bad finish, ruined parts, etc. The expensive stuff sounds expensive but I get very long life out of them.

The fragility of the BG inserts is the basis of my hesitation to spend big/bigger dollars on name brand inserts such as Kennemetal/Korloy etc. But if they are more durable then it makes sense.

I think it has more to do with the grade of carbide more then actual brand. Frequently the imports (cheap) from China are simply low grade - not meant for hard work. If you buy premium you get relatively good results.
For me top of the line premium is usually $3 per insert in carbide (not ceramic). For normal size inserts $3 gets you like ferrari. Last very long time. No issues cutting 4330 at all, even no issues with some abuse.
For tiny inserts premium is around $1.5. This includes best brands like Kennametal etc.
For ceramic there is hard life - you usually cannot go much under say $3 for smaller ones. But most pp don't use these anyways.
I would have rather low expectations of bottom of the barrel pricse wise stuff such as https://www.aliexpress.com/item/329...earchweb0_0,searchweb201602_,searchweb201603_
I mean you are paying few cents per insert. Obviously no real coating and other cost cutting. Excluding shipping you pay less then 4 CAD per box, maybe actual price is like 35c CAD per insert.
You can go pay like 2x as much and go with Israel - https://www.aliexpress.com/item/329...earchweb0_0,searchweb201602_,searchweb201603_
Or go with Mitsubishi.
