When working with hardness, there are essential tools such as brazed diamond drill bits, which are able to perform efficiently within heavy usage cuts. Our drill bits that are manufactured in Beijing DEYI are efficient thanks to complex production technologies and will be suitable for working in all sorts of materials. And the construction of the crowns with brazing allows for enhancing the bond strength even more, and permits even better heat management so that overheating occurs while in use and thus extends the service life of the bits.
