Abstract: A stabilizing collar for a concrete saw blade provides a rigid blade structure for smoother cutting operations, particularly in partially cured concrete. A pair of the present collars are secured to the blade shaft on each side of the blade, clamping the blade securely therebetween. Each collar has a slightly recessed central area and a raised toroidal rim therearound. Clamping the blade and collar assembly tightly on the shaft, compresses the recessed areas and clamps the rim portions of the collars tightly against the blade at some distance outward from the shaft, thereby providing a rigid assembly and essentially eliminating lateral vibration and flexing of the blade. This enables an otherwise conventional concrete saw to be used for cutting “green” concrete, i.e., relatively soft concrete which has only partially cured, without risk of spalling and breaking up of the edges of the cut due to blade vibration thereagainst.
