<p>A circular saw blade includes a substantially circular body having a plurality of protruding tip support regions spaced around the periphery thereof, each tip support region including at least a seat for supporting a cutting tip. The tip support region may further include a substantially planar upper tooth face, a grindable tip reinforcement portion and/or a lower tip angle less than 90 degrees. A cutting tip is secured to the seat of each tip support region preferably with a top face of each cutting tip substantially parallel to and offset from an upper tooth face of each tip support region. Each cutting tip of the circular saw blade is further configured to maintain a cutting edge at a substantially constant width when material is removed from the top face thereof. A method of manufacturing a saw blade is also provided.</p> |
