  • Concrete/masonry cutting device with fast-start design and interlocking reinforcement
    Patent number: 10124510
    Abstract: A diamond cutting tool (200; 200?) for enabling a fast cutting start may include a rotatable main body (210) and a cutting portion (220). The rotatable main body may include a substantially circular periphery. The cutting portion may include an interlocking support assembly (280) and a plurality of notched cutters (270). The notched cutters may be disposed around the circular periphery extending outwardly from the main body. The notched cutters (270) may be formed of a first diamond-metal matrix. The interlocking support assembly (280) may be provided radially outwardly of the notched cutters and may include a softer diamond-metal matrix and/or a different diamond concentration therein than the first diamond-metal matrix. The interlocking support assembly may include a reinforcement portion (284) disposed between the notched cutters (270) and a top section (282) covering radially distal portions of the notched cutters.
