The Makita 9" Ultra-Premium Plus Segmented Diamond Blade is the new standard in diamond blades. Each segment is scrutinized under quality control to exacting standards. The fan-shape of each segment, along with narrow slits, allow for less drag and a faster cutting experience. The 3D Diamond Grid means the diamonds are arranged in a precise 3 dimensional arrangement for optimal cutting speed, reduced noise, lower vibration, and longer blade life. These versatile blades are designed to cut masonry materials including concrete, block, pavers and brick.
