DEWALT, XR Extreme Runtime, DT99561-QZ, 165 mm, Circular Saw Blade

The DEWALT XR Extreme Runtime Circular Saw Blade 165 x 20 mm 42T DT99561-QZ is a circular saw blade built for professional woodworking and construction applications. It is designed for general wood-cutting tasks, including slicing through timber that contains embedded nails. The component can be re-ground up to three times to extend its usable service life on demanding job sites. This pack contains a single replacement part for cordless cutting tools. It is intended for professional tradespeople, contractors, and users who require consistent cut quality on the job site.

Constructed from next-generation C3 carbide, the cutting edge maintains sharpness and impact resistance when encountering hidden foreign objects. A 1.76 mm cutting width paired with a 1.2 mm plate thickness minimises the material removed during each pass. This thin-kerf geometry reduces the load on the saw motor, which helps maximise battery runtime during cordless operation. Weighing 242 g, the blade integrates into the tool without adding excessive mass. The reduced weight and narrow kerf contribute to easier handling and more efficient power consumption during prolonged cutting tasks.
