DEWALT 20V MAX 22" Cordless Hedge Trimmer DCHT821B Bare Tool — 22-inch Hooked-Tooth Blade, Compact Low-Fatigue

The DEWALT 20V MAX 22" Cordless Hedge Trimmer (DCHT821B) is a compact, battery-powered trimmer with a 22-inch hooked tooth blade designed to deliver clean cuts and extended runtime for residential and light-commercial hedge work.

This bare-tool model is built for users who already own DEWALT 20V MAX batteries or prefer to customize their battery and charger setup. It combines a high-output motor and a friction clutch for protection, while a slimmer body and balanced design reduce arm strain during longer trimming sessions. The trimmer's hooked teeth help capture and cut branches up to 3/4 inch thick, and DEWALT rates the tool for up to 78 minutes of runtime when paired with compatible high-capacity batteries.

How long will the trimmer run on a single battery charge?

Runtime depends on the battery capacity you use, but DEWALT's design supports extended operation when matched with 20V MAX batteries. With a high-capacity battery, you can expect prolonged cutting time suitable for whole-yard sessions without frequent recharging.

• Up to 78 minutes runtime with compatible batteries (per DEWALT guidance).
• Higher amp-hour (Ah) batteries deliver the longest continuous use.
• Interchangeable with the DEWALT 20V MAX battery platform.

What kind of cutting performance can I expect on thick branches?

The trimmer uses laser-cut, hooked-tooth blades and a robust motor to manage branches up to 3/4 inch thick. You’ll get cleaner, more consistent cuts compared with standard non-hooked blades, making it easier to shape hedges and remove overgrowth.

• 22-inch hooked-tooth blades for improved grabbing and cutting.
• High-output motor designed for dense shrubs and woody stems.
• Clean, fast cuts that reduce tearing and promote a neat finish.

How does the tool protect itself and reduce operator fatigue?

DEWALT includes a friction clutch to help safeguard the transmission if the blades meet an obstruction, reducing the risk of internal damage. The trimmer’s compact footprint—39% smaller than some prior models—improves balance and maneuverability, lowering arm and shoulder strain during extended use.

• Friction clutch helps prevent transmission damage from jams or blockages.
• 39% more compact design enhances control and reduces fatigue.
• Well-balanced housing for comfortable handling in tight spaces.

What accessories or extras should I consider with this bare tool?

Because this listing is the bare tool only, you’ll need a compatible DEWALT 20V MAX battery and charger to operate it. Choosing the right battery capacity and adding protective gear or a dedicated storage case will improve the trimmer’s convenience and longevity.

• DEWALT 20V MAX batteries (higher Ah for longer runtime).
• DEWALT charger compatible with your selected batteries.
• Personal protective equipment: gloves, eye protection, and hearing protection.

Who is this for: The DCHT821B suits homeowners, landscapers, and contractors who already use DEWALT 20V MAX batteries or want to integrate a powerful cordless hedge trimmer into their 20V ecosystem. It fits users who need a compact, reliable trimmer for shaping hedges, trimming ornamental shrubs, and removing light overgrowth while prioritizing cleaner cuts, reduced fatigue, and tool protection features.
