ABSTRACT:
A masonry blade adapted for cutting green concrete and asphalt reduces undercutting and extends blade life by generating turbulent flow within the swarf adjacent to the bond line between the cutting segments and the blade core. Turbulence is created by forming the leading surface of at least one of the cutting elements with a radial dimension greater than its trailing surface and greater than corresponding surfaces of standard elements. The opening of the blade gullets is maintained within predetermined limits to prevent blade vibration.
