The Chicago Electric Double Cut Saw, a Harbor Freight tool, features two counter-rotating blades for cutting metal without kickback or material rotation, and is known for its ability to cut through various materials, including steel, aluminum, and wood. Here's a more detailed look: Unique Design: The saw's defining feature is its two, counter-rotating blades, which cancel out kickback and prevent material from spinning during the cut. Material Versatility: It's designed to cut through a wide range of materials, including steel, aluminum, wood, and even some plastics. Clean Cuts: The saw is known for producing clean cuts, even when cutting metal, with minimal flashing compared to abrasive cut-off wheels. Safety Features: The blades are almost completely shielded, and the saw generates a fine mist of metal particles when cutting steel, so safety goggles are recommended. Blade Lubrication: There's a blade lube feature for use on stickier metals like aluminum or sappy woods. User Feedback: Some users have reported issues with the power switch being difficult to use and potentially burning out after limited use. Precise Cuts: If precise cuts are needed, a fence may be required, as the saw blades are shielded, making it difficult to see the cut line. Model Number: The model number for this saw is CHICAGO TOOLS 68316. Power: The saw is corded and has a 120V brushed motor with a maximum speed of 42000rpm. Blade Diameter: The blade diameter is 5 inches. Cutting Angle: The saw is suitable for cutting at a 90° angle.
