This chain has a preset ground diamond segment on each link, making it immediately ready to cut concrete and stone. It is designed to provide high cutting speed, smooth cutting, and excellent performance during plunge cutting. The diamond cutter head reduces vibration and improves the overall cutting speed. The depth gauge between each diamond segment improves the chain's robustness and plunge cutting performance. The chain also has a "sandwich" section design, which can achieve faster cutting and longer service life. In 6-inch thick concrete, the expected service life is about 40-80 feet for straight cuts (it will vary greatly depending on the aggregate and steel rebar).
