The Snapper Shear fiber cement siding shear combines precision-machined cutting head with a powerful 1/2 inch drive motor. Geared toward the professional, the Snapper Shear SS404 effortlessly powers through fiber-cement siding for fast clean cuts with minimal airborne dust. Designed specifically for 5/16 inch fiber cement siding cutting, the solid steel blades are reversible and fully replaceable. The Snapper Shear design actually shears the cement siding rather than cutting it, resulting less mess, minimal airborne dust and faster clean-up.
