Fluid-cooled apparatus for cutting concrete material and the like

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