The DeWalt DC490B cordless shear is designed to slice through cold-rolled steel ranging from 28- to 18-gauge with uncompromising speed and accuracy. It was specifically engineered for metalworkers, HVAC contractors and others who earn a living working with sheet metal, and fabricating and installing air-conditioning and heating ducts. The tool is powered by an 18-volt battery, which drives hardened-steel blades at a metal-shearing 2,300 strokes per minute (SPM). As it slices through metal, it removes a 7/32-inch-wide ribbon of waste material that curls up and out of the way of the cut line. The DC490B is equipped with a 360-degree swiveling head that permits you to comfortably cut at any angle or awkward position, in extremely tight quarters, and radii as tight as 5-1/2 inches. And it’s cordless, so there’s no cord to drag around, a real benefit when working in ceilings, attics and cramped crawlspaces. The shear comes with a blade wrench for quick blade changes. It’s backed by DeWalt’s 90-day money-back guarantee, full one-year service contract, and three-year limited warranty. Battery and charger sold separately.
  • Head swivels 360 degrees, allowing user to access tight quarters while maintaining comfort
  • Cuts 7/32 in. strips, which continuously curls out of the cutting area providing consistent and accurate cuts
