PORTER-CABLE 12870 Riptide 4-1/2-Inch 20 Tooth ATB Thin Kerf General Purpose Saw Blade with 3/8-Inch Arbor
The Porter-Cable 4-1/2-Inch 20-Tooth Thin Kerf Riptide Saw Blade reduces drag on the motor, allowing the saw to cut more effectively. The teeth are made of fine-grained tungsten-carbide to stay sharp longer. Each tooth is ground on all four exposed sides for maximum sharpness. Even though the blade is thinner than standard blades, the body is fully heat-hardened and has computer-mapped cooling vents to maintain trueness.
