The Amana Tool® Prestige™ general-purpose blade cuts smoother and stays sharper, for longer, in solid wood, plywood, MDF and chipboard. It features a massive tool-steel plate (.102" thick!) with expansion slots and copper plugs that practically eliminate vibration. The 40 teeth are ground with a steep 20° bevel angle, alternating left and right, for crisp, clean cuts both across grain and with the grain. The 18° hook angle yields an effortless feed. The precision-ground D-10 carbide teeth are individually computer-verified to have minimal runout.
