Diamond wire saw bead is the function part of the diamond wire saw. According to the manufacturing technology, diamond beads have 3 types: electroplated diamond beads, vacuum brazed diamond beads, and sintered diamond beads. Because of the problem of environmental pollution, electroplated diamond beads are becoming less and less. Vacuum brazed diamond beads bring extra sharpness. They are specially designed for fast cutting of concrete and reinforced concrete, to fit the project whose cutting speed is required. Sintered diamond beads are widely used in cutting all kinds of stones like granite, marble, concrete, reinforced concrete, and others. Not as fast as the vacuum brazed one, but it has a much longer lifespan. These 11mm vacuum brazed diamond wire saw beads are specially designed for fast cutting of concrete and reinforced concrete. Different typical type, it has two layers, which brings longer lifespan. If your projects need the fast cutting much more than the lifespan, it is a good choice.
