This core bit is made by bonding diamond crystals directly onto the drill surface with a very hard nickel chromium alloy and then it is subject to permanent brazing in a special vacuum brazing furnace. The result is extraordinary. It is very sharp and the drilling performance is constant until the diamond crystals are completely worn flat. Unlike what you might think, the life is comparable to that of the classical metal matrix type. As diamond crystals are doing the drilling all the time, this type of core bit works both for hard materials such as granite and soft material such as marble....Take advantage of the latest and improved DIAMOND BRAZING TECHNOLOGY.
