  • Compact and Ergonomic: Weighing just 840 grams, the WX801.9 is ideal for one-handed operation and excels in tight spaces and overhead work.
  • 20V PowerShare Battery: Compatible with Worx’s PowerShare battery platform, allowing you to use the same battery across multiple Worx tools (battery and charger sold separately).

  • Versatility: Includes 3 cutting blades and a grinding disc for tackling different cutting and grinding tasks.
  • Sliding Switch: Ensures easy control between cutting and grinding functions.


  • Cutting: The WX801.9 handles light to medium-duty cutting tasks effectively. Users report clean cuts in metal sheets, plastic pipes, and ceramic tiles.
  • Grinding: The included grinding disc is suitable for light grinding applications like smoothing welds or sharpening tools.
  • Maneuverability: The compact size and ergonomic design make the grinder comfortable to use for extended periods, especially in confined areas.
  • Battery Life: While run time depends on battery capacity (not included), the efficient motor allows for extended use on a single charge (battery sold separately).

Potential Drawbacks:

  • Limited Cutting Depth: Due to the small disc size (76mm), the WX801.9 isn’t ideal for deep cuts in thick materials.
  • Not for Heavy-Duty Grinding: The motor is powerful for its size but may not handle heavy grinding applications effectively.
  • Sold as Bare Tool: Battery and charger are sold separately, adding to the overall cost.

Overall :

The Worx WX801.9 Chopper is a valuable tool for DIYers, hobbyists, and professionals who need a compact and versatile cordless cutter/grinder for light to medium-duty tasks. Its maneuverability and ease of use make it a great option for working in tight spaces. However, if you require a tool for heavy-duty grinding or deep cutting, a larger corded or higher-powered cordless grinder might be a better choice.
