These tools are not well finished during machining. I had to debur each one with ruby stones.Once debuted the worked great and produced a beautiful finish.If you’re hoping for a high quality product without needing to debur you need to pay a lot more. But with a little work you get a great tool at a good price.

Yeah.Tough to get a picture of what I see.What you should see in the pics is the holes are not debur and not polish.Like if they drill the hole and leave it there.Outside looks well and fine, and they cut good for the price.Don’t think you are getting a super deal, but they are nice for that price.Don’t how long they will cut.Will update if anything goes wrongCheers

Pleased with both the quality and cost of these countersink bits. Doubt there is much better at this price point.
