How It Works: Dual-Blade Buzz Saw
To saw different materials, users often need to switch blades. A blade with big teeth, for example, cuts wood quickly because it scoops out a lot of material with each tooth. But those same big teeth make the saw kick back toward the user if applied to a harder substance such as steel. Conversely, a blade with small teeth won't cause kickback on steel but is needlessly slow on wood. The new TwinBlade Saw from Ridgid cuts through nearly any material without requiring the user to change blades. Instead of employing one blade, the TwinBlade rotates a pair in opposite directions. Because two blades are working at once, the saw cuts faster. And the opposing spinning motions balance each other out, minimizing kickback.
