We apply the latest vacuum brazing technology to our core bits. They are much more aggressive than the regular ones. What is more, they have double working life! The 40mm (1-3/5") wide brazed diamond wall on the bits makes the holes drilled much smooth, they can be used to enlarge holes also. You can also use it as a drum wheel. It can be used dry or wet on most materials, such as granite, marble, porcelain, ceramic and concrete.
