The Festool Saw Blade HW 160x1,6x20 W18 is an 18-tooth general-purpose blade for the HKC 55 K, TSC 55 K, and TSC 55 KS cordless track saws, built for fast rip and cross cuts across solid wood, chipboard, cement-bonded board, hardboard, and drywall without a blade change. Its 1/16 in. (1.6mm) thin kerf lowers cutting resistance, which reduces power draw and extends runtime per battery charge on cordless saws. The blade is made from high-quality steel with fine-grain carbide teeth, ground in an alternating top bevel pattern with a 15-degree chip angle. Diameter is 6-5/16 in. (160mm) with a 20mm arbor bore.
