Vacuum brazed diamond saws are manufactured by brazing synthetic diamond particles to the outside edge of the circular saw blade in a vacuum brazing furnace. All of the diamond particles are on the exterior cutting edge of the blade, with no metal-diamond mixture. Depending on the manufacturer's recommended blade application, vacuum brazed blades will cut a wide variety of material including concrete, masonry, steel, various irons, plastic, tile, wood and glass.

Vortex Diamond WTVD series is a supreme quality vacuum brazed segmented blade with the rescue/fire/accident designation, the specially designed to cut ductile iron, which has the side protection diamond to help with the beveling process on pipes.
