An improved cutting blade is provided for cutting and thinning brush and small trees. The blade comprises a substantially circular disc having a plurality of removable, solid carbide cutters circumferentially spaced along the edge of the disc. A plurality of circular cavities are spaced circumferentially forwardly from each cutter to provide a radially extending opening for receiving and clearing saw chips away from the blade. The cutters are removably secured to the blade in cutter slots, having elongated linear openings extending rearwardly therefrom. A plurality of mounting bolts and receiving members extend perpendicularly through the linear openings from the edge of the blade for selectively compressing the cutter slots and securing the cutters. The design of the present invention decreases the incidence of blade jams and kick backs and increases the cutting efficiency and safety of the blade. The cutters are designed to be easily removed and sharpened or replaced at the job-site, decreasing "down time" and maintenance expenses.
