Abstract: In one embodiment of saw tooth assembly, the tubular saw tooth is releasably inserted with friction fit inside the hollow of a tubular mount. In an alternate embodiment, it is the tubular mount which is releasably inserted with friction fit inside the hollow of the tubular tooth. In both cases, the hollows of the mount and tooth are coextensive, whereby a common axial through-channel is defined. The tubular mount is to be anchored to the peripheral edge of a circular saw discoid plate. The wood chip generated during circular saw operation can therefore freely engage through the common through-channel, i.e. through the whole saw tooth assembly, and escape therefrom. Wood chip clogging of the saw tooth during sawing operations is therefore substantially prevented, and the aerodynamic features of the circular are accordingly enhanced.
