The Construct Wood Circular Saw Blade is durable when cutting construction site timber. Its high-quality precision-ground carbide teeth make the blade robust for tough applications. Moreover, its expansion slots lower vibration during use, which dampens noise and reduces heat development. The blade features a base blade made of dimensionally stable SK5 hardened steel (> 40 HRC) which ensures accuracy. • Durable When Cutting Construction Site Timber with Nails and Concrete Residues • High-quality precision-ground carbide teeth make the blade robust for tough applications • Expansion slots lower vibration during use, which dampens noise and reduces heat development • Base blade made of dimensionally stable SK5 hardened steel (> 40 HRC) ensures accuracy • Blade for hand held/table saws has HB teeth that make it nail-proof.
