The carbide nail drill bits are always the popular material bits for the clients. Because not only it's sharp and durable,but also can be able to coat many beautiful colors.

Recently we've launched new kind of coating for our clients who are always support us.I call it B-7C coating. It means brighter 7 colors. And quality become much more higher and more stable than any other coating colors. 5 times more durable than others.

Quality become more higher due to the hardness of bit go up another level. Don't hesitate to try it!You will definitely love it.
