Up to 80 nails per minute productivity
+ Show Review

The new Worx WX840 cordless nailer is basically a machine gun except it shoots nails instead of bullets. It fires as many as 80 nails per minute, which should be plenty enough since it is probably faster than you’ll be able to shoot.

  • ​​​​Air impact tech places each nail or staple just right, using less charge, with less wear and tear on the tool.
  • Quick depth adjustment
  • Switch between sequential (single nail) or contact (bump fire) actuation modes
  • Two LED work lights on the sides
  • Up to 80 nails per minute firing rate
  • Dry-fire lockout feature extends tool life
  • 2 tools in 1 compatible with both brad nails and staples
  • Part of the Worx PowerShare battery platform


Product description

The new Worx WX840 cordless nailer is quite a predictable machine: as the name says, it shoots nails. To be fair, it does shoot staples as well, as long as they have a narrow crown. It’s rather quick, with a firing rate of up to 80 nails per minute, and it has a push-button magazine release for easy and fast loading. It’s ideal for several applications on different materials, including carpeting, underlay, plywood, hardboard, plastics, fencing, insulation, moulding, beading, roofing, upholstery, craft work, and so much more. In order to adapt to all of them and protect the workpiece, it also has a tool-less depth adjustment. This tool is part of the expanding Worx PowerShare, one of the most versatile cordless platforms that covers power tools, lawn and garden tools and everyday life products. PowerShare's "One Battery, Expandable Power" means the same 20V battery can be used in multiple configuration to power up 40V and 80V products.
