Concrete is an important material in the construction field, and we can find it in everywhere - buildings, road, bridge, wall, etc. According to different projects, the steels in the concrete can be different. In some projects, the steel content is high, While in other projects, the steel content may be very low. Sunny Superhard Tools recommend you the right diamond saw blade for different applications: For cutting concrete with high steel content: We recommend the laser-type concrete cutting blade. Because the weld strength of the laser type diamond blade is very high, thus the diamond segment won't be drop when impacting with the steel. For cutting concrete with low steel content: We recommend the high-frequency concrete cutting blade. Because the weld strength high-frequency welded diamond saw blade is enough and it is much cost-effective. Other sizes of diamond cutting blade for concrete: Diameter Segment Size Segment Nos.
