Concrete requires a specific saw blade that can cut through hard materials. Concrete Blades are laser welded and have narrow segments that get larger on the bottom like tear drop shaped notches. This feature makes these blades capable of cutting very smoothly into hard materials. A soft bond is required for a faster wear rate so the blade will cut for as long as it lasts. Concrete saw blades are used for cutting concrete, hard concrete with reinforced bar, block, brick, hard brick, pavers, clay pavers and field stones.
