Achieve Clean and Precise Metal Cuts with the DEWALT 20V MAX 18-Gauge Swivel Head Shears

The DEWALT DCS491B 20V MAX* 18-Gauge Cordless Metal Shears are engineered for professional HVAC technicians, roofers, and metal fabricators who demand precision and maneuverability. Featuring a versatile 360-degree tool-free swivel head, these shears allow you to navigate tight corners and awkward angles with ease while maintaining an ergonomic grip. The tool is capable of slicing through 18-gauge mild steel and 20-gauge stainless steel at speeds up to 2,300 strokes per minute, producing a clean 7/32-inch strip that continuously curls away from the work area. This ensure a clear line of sight and prevents the material from binding, resulting in consistent, burr-free edges on every project.

Built for the modern job site, the DCS491B eliminates the need for cumbersome air hoses and power cords, providing true cordless freedom. The integrated LED work light provides superior visibility in dark crawlspaces or cabinets, ensuring your marks are always visible. Whether you are trimming metal roofing, cutting ductwork for ventilation, or fabricating custom metal components, these shears offer the power and runtime needed for high-production environments. As a bare tool, it integrates seamlessly into your existing DEWALT 20V MAX battery ecosystem, allowing you to maximize your current investment while upgrading your cutting capabilities. **Battery and charger sold separately.

Pro-Tip

Pro-Tip: To achieve the smoothest edge and longest blade life, always keep the metal sheet flat against the base of the shear head. If you are cutting along a curved line, utilize the 360-degree swivel head to position the tool body away from the material, preventing the metal from hitting the battery pack. For the cleanest results in stainless steel, consider using a light lubricant like cutting oil along your mark to reduce friction and heat buildup during fast cuts.
