These 10mm indexable metal lathe turning tools, with carbide inserts, from the QIANJIEER Store are very well made, with excellent machining, fit and finish. I mostly machine some steel, aluminum, and ABS plastic, and prefer the carbide inserts. They cut well and last a long time. I'm not fond of carbide for acrylic, but I do very little of that.The shanks, and fitment are as good as any I've seen or used. This set has more range than other sets that I've bought, and I look forward to seeing how the different bits perform.
