The Nor’Easter MK-313 diamond blade for cutting concrete is designed with extra core cutouts that provide improved cooling during deep cutting, helping to keep the core from warping or losing tension. The blade can be used wet or dry due to the laser-welded segments and features a combination of segmented and turbo segments for cutting concrete overlay applications. The wet/dry cutting diamond blades are available in 12-in. to 18-in. diameters. MK Diamond Products. 800-421-5830.
