Heavy-Duty Rebar Cutting: Selecting Blades That Power Through Steel Mesh Without Chipping
Direct Answer: Selecting diamond blades for heavy rebar cutting requires choosing laser-welded blades formulated with medium-soft cobalt matrices and high diamond concentration. When cutting concrete embedded with #4 to #8 steel rebar or wire mesh, soft-bond segments prevent glazing when striking solid steel, while keyhole cooling slots dissipate intense thermal buildup, preventing segment loss and saw spindle binding.
