Circular Saw Blades Video
Circular saw blades are not all created equal. To achieve the right cut, you need the right blade for your circular saw. Blades are designed to cut metal, wood, plastics or ceramic tile or stone.
Some saw blades have no teeth, but have small diamonds on the edge for cutting. A blade with fine teeth are good for plywood with fewer splinters.
Carbide blades with 30 teeth are good for cutting thin metal and rough lumber. An 18 tooth carbide teeth saw blade is good for rough cuts in framing lumber.
Remember match the right saw blade for your cutting job.
