The Cobra wire, which is the universal wire, handles cutting in reinforced concrete and even extreme tasks as iron sawing. It cuts faster and lasts longer than standard electroplated/sintered wire. A Cobra wire is a vacuum brazed wire that is developed specifically for demanding applications like dry and wet cutting in reinforced concrete, and in solid or hollow steel. The vacuum technology enhances durability and performance. Vacuum technology uses active welding, one of the strongest welding methods, making for extra hard bonds and excellent diamond retention.
