The Malco FCS Fiber Cement Siding Hand Snips are designed specifically for making precise arc and trim cuts in fiber cement siding. This tool is recommended for cutting 5/16" James Hardi and Certainteed Siding products. Shearing fiber cement products with this tool creates much less dust than sawing or drilling. Unique ergonomic design allows the user to operate the tool from the bottom of the material. This way lines and shapes can be marked on the finished side of the panel and easily be followed with the center blade of the tool, which is on the top of the panel. The FCS features heat treated alloy steel blades for long service life and uses compound leverage for easy one handed operation.
