Worx Nitro 20V Cordless 18-Gauge Narrow Crown Stapler: specs and who it suits

The Worx Nitro WX844L.9 is a battery-powered narrow crown stapler for 18-gauge staples. It fires without an air compressor, hose or gas cartridge, which suits trim, cabinet backs and underlayment work where dragging a hose around is a nuisance. The model number ending in .9 means it is sold as a tool only: the battery and charger are separate.

How it drives staples

Worx says its Air Impact Technology fires up to 80 staples per minute and about 500 shots per charge. As the name suggests, the tool uses a self-contained air-driven mechanism rather than a plain spring or solenoid, which is meant to sink staples into harder materials. Worx says it sinks staples from 3/4 to 1.5 inches into hardwoods such as maple and oak. Real shot counts depend on the battery size, the wood and the staple length.

Two firing modes

• Contact Actuated Mode lets you bump-fire: hold the trigger and tap the nose against the work to fire quickly, which suits repetitive fastening.
• Single Sequential Mode requires the nose to touch the work first and then the trigger to be pulled, one shot at a time, for precise placement.

A tool-free depth adjustment dial sets how deep the staples sit, so you can avoid leaving them proud or driving them too deep into soft stock.

Jams, empty magazine and safety features

Worx describes a tool-free jam release: lift and unhook the lever to clear a jam. An anti-ejection design keeps staples in place whenever the magazine is open. A dry-fire lockout stops the tool firing when the staples run out, and a low-staple indicator warns you beforehand. As with every nailer or stapler, read the manual, wear eye protection, and keep hands clear of the nose.

Handling and visibility

The stapler weighs about 7 lb (roughly 3.2 kg). The narrow nose is meant to give a clear view of the work surface and to reach into cabinetry and tight spaces. Dual LED lights illuminate dark corners, a rubberized grip is for comfort in longer sessions, and a non-marring pad at the tip protects surfaces. The listing gives the dimensions as about 11.8 x 11.2 x 3.5 inches.

Battery platform

It runs on a Power Share 20V battery, which isn't included. Worx says the same battery works with more than 140 tools, outdoor power equipment and lifestyle products in the Power Share range. If you already own the batteries, a tool-only stapler adds capability without duplicating them.

In the box

A belt clip, a carry bag and 200 1.25-inch 18-gauge narrow crown staples. There is no battery or charger.

Who it suits

It suits home renovators and woodworkers who do trim, cabinet backs, small carpentry and underlayment, and anyone who wants cordless convenience. It isn't a framing tool; narrow crown staples hold light to moderate fastening jobs.

What to check before you buy

• Battery and charger: you need a compatible Power Share 20V battery and charger.

• Your material: check that the holding power of narrow crown staples suits the job.

• Spare staples: 200 is a small starter supply.
