ABSTRACT:
A saw blade is provided which includes an inner collar separated from an outer collar with a resilient isolated layer. The inner collar fastens to the arbor shaft of a driving motor, while the outer collar is welded to the rim containing hardened particles, such as diamond bits. The inner and outer collars form inner and outer collar flanges which receive the resilient isolating material therebetween. In an alternative embodiment, the inner and outer collars are separated from one another with a plurality of plugs formed of resilient isolating material. The plurality of plugs are formed in a circular pattern about the arbor shaft and are spaced apart from one another. In another embodiment, a vibration dampening coupler is fastened to the arbor shaft and formed separate from the cutting blade. The isolating resilient layer may be formed as a solid layer, as a plurality of O-rings, or with a void therein.
