Abstract
The present invention includes a reversible concrete cutting saw blade and one or two blade attachment plates having radial grooves formed in the blade engaging faces thereof, such that when the plates and blades are joined, radial passageways are formed between the plates and the blade. An inlet tube, communicating with a rotatable inner hub introduces cooling fluid into internal passage ways within the hub under positive flow conditions, thereby causing the fluid to flow through the hub to the radial passageways in the plates and then be centrifugally dispersed down the grooves along the surfaces of the blade.
