Key Features

  • Advanced Control System: Equipped with the DEWALT® ANTI-ROTATION System, this tool quickly stops the wheel upon sensing a pinch, stall, or bind-up event, significantly reducing reactionary torque and maximizing user control. The electronic brake further enhances safety by stopping the wheel in less than one second after the trigger is released.

  • Rapid Wheel Changes: The integrated spindle lock facilitates quick and easy wheel changes, eliminating the need for multiple wrenches and improving workflow efficiency.
  • Ergonomic and Versatile Design: Its slim, ergonomic design allows for superior maneuverability in tight or awkward spaces. The rotating guard offers 11 positions for optimal cuts at various angles, with tool-free adjustments up to +/- 75 degrees.
  • Jobsite Connectivity: The tool is TOOL CONNECT™ CHIP READY™, allowing it to be paired with a TOOL CONNECT™ Chip (sold separately) and software for jobsite data and management.
