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. #PR1040C, (D) Diameter: 10 (250mm), Teeth: 40, (d) Bore: 5/8, Tooth Grind: ATB, Hook Angle: 18°, Kerf (B): . 134 (3. 4mm), Plate (C): . 102 (2. 6mm), PR1040C Electro-Blu Carbide Tipped Prestige General Purpose 10 Inch Dia 40T ATB, 18 Deg, 5/8 Bore, Non-Stick Coated
