Worx Nitro 20V Cordless Crown Stapler WX843L.9 - Powerful 2-in-1 Tool

In this review the Worx Nitro 20V Cordless Crown Stapler WX843L.9 is evaluated for homeowners and light pros needing a fast, portable stapler that also accepts brad nails. The bottom line: its Air Impact Technology and long battery run time make it a standout for repetitive fastening tasks, while the easy-squeeze trigger reduces hand fatigue compared with manual guns. It ships with a 20V 2.0Ah Power Share battery and charger, so users get immediate cordless use and up to 2000 shots per charge in typical conditions.

Key Features

• 2-in-1 fastening: Switch between crown staples and 19/32 in brad nails to cover a wider range of trim and upholstery jobs without changing tools.
• High-efficiency Air Impact: Fires up to 80 staples or nails per minute for faster completion of repetitive tasks on projects like insulation, roofing felt, and trim.
• Long run time: A standard 2.0Ah Power Share battery can deliver up to 2000 shots, minimizing downtime and the need for frequent recharges on medium jobs.
• Ergonomic GripZone: Micro-textured handle and an easy-squeeze trigger reduce hand strain for extended use compared with manual staple guns.
• Tool-free depth adjustment: A precision knob lets users set staple and nail depth quickly to avoid surface damage and ensure proper holding power.
• Quick-load magazine: Easy-release magazine and an easy-view window make reloads and inventory checks fast on the job.

Who It's For

The Worx Nitro WX843L.9 is best for DIYers, carpenters doing light trim work, and contractors who want a cordless, portable solution for crown stapling and occasional brad nailing. Its combo capability and included 2.0Ah battery make it a practical choice for jobsite mobility and multi-task projects where carrying a compressor is inconvenient.

Those who need very high-volume industrial stapling or consistently heavier-duty framing should look elsewhere, as this model is positioned for medium-duty fastening and portability rather than continuous heavy production use. Users sensitive to weight should note it is designed for balance and comfort rather than ultra-lightest build.
