Worx Nitro WX844L 20V Cordless Narrow Crown Stapler: specs and who it suits

The Worx Nitro WX844L is a cordless stapler that fires 18-gauge narrow crown staples without a compressor, hose or gas cartridge. It runs on a 20V Power Share battery and is aimed at finishing work, underlayment and small carpentry jobs. Here is what its features mean in practice.

How it works without a compressor

Pneumatic staplers need an air compressor and hose. Worx says this tool uses its Air Impact Technology to drive staples from the battery alone, which gives you the mobility of a cordless tool. The brand rates it at up to 80 staples per minute and 500 shots per charge. Actual numbers vary with the staple length, the wood and the battery's state of charge.

Staple size and materials

The stapler takes 18-gauge narrow crown staples from 3/4 inch to 1.5 inches (about 19 to 38 mm) long. Worx says it sinks them into hardwoods such as maple and oak. The listed jobs include trim, cabinet backing and underlayment. A narrow crown staple leaves a smaller mark than a wide one, which is why it is used for finishing rather than heavy framing.

Firing modes

Two modes are available:

• Contact actuated: for rapid bump firing, where you press the nose against the work and pull the trigger. It is fast for repetitive jobs.
• Single sequential: for precise, one-at-a-time shots, where the sequence of nose and trigger matters. It is better for placement.

A tool-free depth adjustment dial controls how deeply each staple sits, so you can set it flush or slightly countersunk.

Jams, loading and warnings

If a staple jams, the tool-free release lever lifts and unhooks to clear it, with no tools. Worx adds an anti-ejection design that keeps staples in place when the magazine is open. A quick-load magazine, a low-staple indicator and a dry-fire lockout stop the tool firing when it is empty, which avoids marking the work.

Visibility and handling

The narrow nose is meant to give a clear view of the work surface, and dual LED lights help in dark spots like cabinet interiors. A non-marring tip pad helps protect finished surfaces. The tool weighs about 7 lb (around 3.2 kg), has a rubberized soft grip and comes with a belt clip. Its listed dimensions are about 11.8 x 11.2 x 3.5 inches (30 x 28 x 9 cm).

What's in the box

The listing says the package includes the stapler, a belt clip, a carry bag, 200 1.25-inch 18-gauge narrow crown staples, a 2.0Ah battery and a charger. The product description ends with a note that the battery and charger aren't included, which conflicts with the feature list, so check what your package contains before relying on either.

Who it suits

It suits DIYers and tradespeople doing trim, cabinetry and light carpentry who want to avoid hoses and compressors. Anyone with Power Share batteries can share them across the Worx range, which the brand says covers more than 140 tools.

What to check before you buy

• Battery and charger: confirm whether they are included in the version you are buying.
• Staple type: it takes 18-gauge narrow crown staples only; check the length range.
• Materials: consider the wood hardness and thickness you will staple into.
• Safety: wear eye protection and keep hands away from the nose, as the manual directs.
• Run time: 500 shots per charge suits most projects, but plan a spare battery for long jobs.
