The DEWALT Extreme Framing Circular Saw Blades have a thin kerf (cutting width) to ensure that less push force is required by the user and that they cut straighter with reduced binding. The durable teeth stay sharp for a long time with reduced breakage. Can be used for ripping and cross-cutting natural timbers. Cutting composite wood based sheet materials e.g. plywood, MDF and chipboard.  They are suitable for use with portable and stationery circular saws.
