§ FAQ

What is the difference between the DCHT821B and the DCHT821P1?

The DCHT821B is the bare-tool version — it includes only the trimmer body with no battery or charger. The DCHT821P1 is the full kit that includes a DCB205 20V MAX* 5.0Ah battery and charger. If you already own DEWALT 20V MAX batteries, the DCHT821B is the more economical choice.

What battery does the DCHT821B require?

The DCHT821B accepts any DEWALT 20V MAX* battery. For extended trimming sessions, a 4.0Ah or 5.0Ah pack is recommended. DEWALT rates the included 5.0Ah battery (sold separately with the P1 kit) for up to 78 minutes of runtime.

How compact is the DCHT821B compared to the older DCHT820?

The DCHT821B is 39% smaller than the DCHT820 platform, making it noticeably easier to maneuver in tight spaces and around shaped hedges where a full-size trimmer is awkward.

Does the DCHT821B have a friction clutch?

Yes. A friction clutch is built in to protect the transmission if the blades encounter a hard obstruction during use, reducing the risk of gear damage.

What is the maximum branch thickness the DCHT821B can cut?

The DCHT821B is rated for branches up to 3/4 in. in diameter. Larger woody growth should be removed with loppers or a pruning saw before trimming.
