This diamond wire saw is vacuum brazed type and is fixed by rubber. It is designed for fast cutting of concrete and reinforced concrete. 11mm vacuum brazed wire saw beads deliver high performance. The normal type vacuum brazed wire saw beads have only one layer. Different from the normal type, we use two layers type vacuum brazed beads on this concrete wire saw, which lengthens its lifespan. According to the manufacturing process, the diamond wire saw beads can be divided into 2 types: the vacuum brazed type and the sintered type. These 2 types of diamond wire saw beads have different features and are used for different applications: Diamond Wire Saw Vacuum Brazed Type Sintered Type Material to Be Cut   Marble, Concrete, Reinforced Concrete, Steel  Almost all the materials Feature  Fast Cutting  Economical Lifetime  Shorter  Longer Price  Higher  Lower Vacuum brazed diamond wire saw has a better sharpness than the sintered wire saw, but it has a shorter lifespan and more expensive. It is usually used for fast cutting of concrete, reinforced concrete, steel, and other valuable stones like jade, etc. Despite the short lifespan, some projects like concrete cutting need the fast cutting most, so it is good to choose vacuum brazed diamond wire saw.
