4 X 4 Diamond Blades
Norton/Saint-Gobain Abrasives
www.nortonabrasives.com

Diamond blades are typically engineered to specific application and machine. The bond or segment height needed for one job can be completely different from another. Yet, we know that contractors are inclined to use the same blade.

Norton has developed a solution that will allow one blade to cut a range of construction materials without sacrificing performance. The new Norton 4 X 4 diamond blade utilizes unique design technologies to create a multi-purpose blade for wet or dry cutting. The patent-pending steel core design with stroboscopic depth indicators offers control. The outer laser cuts are shaped liked arrows to indicate the true rotation of the blade. This reduces potential error of putting the blade on backwards that could result in glazing or even damaging the segments. These same indicators also help control depth of cut. During blade rotation, the laser cuts create a stroboscopic window that provide the operator visual assurance of the appropriate depths when step cutting while assisting in the release of heat and debris from the cut. A tall .472-inch laser welded diamond segment provides the versatility of cutting concrete, reinforced concrete, granite, building materials, thin steel sections, angle iron up to a half-inch material thickness and rebar up to no. 5.
