Why you should trust this review
We maintain established hedges including formal boxwood borders, arborvitae screens, and ornamental privet on our testing property. We trim these hedges 3 to 4 times per year and have evaluated the long-term blade retention and cutting consistency of each tested model over a full growing season.
How we tested corded hedge trimmers
We trimmed a 40-foot boxwood hedge and a 20-foot arborvitae row with each trimmer, measuring cut speed, stem completion rate (percentage of stems cut in single pass vs. requiring a second pass), and vibration level. We also evaluated blade heat after a 20-minute trimming session and checked for any blade oil requirement indicators.
Who should buy the DEWALT DCHT820B?
Homeowners with established formal hedges that require regular maintenance trimming. Those with woody, mature boxwood or arborvitae where lesser trimmers bog or require second passes. Anyone who wants a hedge trimmer that will remain sharp and effective through multiple seasons without blade sharpening.
DEWALT DCHT820B: the best corded hedge trimmer
The laser-cut hardened steel blade is the defining long-term advantage of the DCHT820B. Laser-cut blades have more precise tooth geometry and significantly harder surface hardness than stamped blades, which translates to better edge retention over time. In our side-by-side test with the BLACK+DECKER at the same starting sharpness level, the DEWALT blade produced noticeably cleaner cuts on arborvitae stems after 40 feet of trimming, while the BLACK+DECKER began showing slight stem crushing rather than clean cutting.
The full-wrap front handle design allows the trimmer to be held in horizontal, vertical, and angled positions with equal comfort, which is important for the varied angles required to trim hedge tops, sides, and interior growth access points in a single session.
BLACK+DECKER BEHT350: the best value for typical homeowners
For homeowners trimming boxwood borders and privet 2 to 3 times per season, the BLACK+DECKER delivers adequate cutting performance at a significantly lower price. The blade stays sharp through standard seasonal use without the premium hardening of the DEWALT. For infrequent use on standard hedge species, the cost savings are substantial and the performance difference is negligible. For heavy use on mature woody hedges, the DEWALT’s blade quality justifies its premium.
What to look for in a corded hedge trimmer
Blade length for your hedge dimensions. Longer blades are faster on long straight hedge faces. Shorter blades give more control on curves and topiary shapes. Choose based on your specific hedge configuration.
Blade material for long-term performance. Laser-cut or hardened steel blades cost more but retain sharpness significantly longer than standard stamped blades. For annual blade replacement cost savings, the premium blade pays for itself within two seasons.
Handle configuration for your cut types. If you primarily trim hedge tops, a standard forward handle is adequate. If you trim sides and angles regularly, a rotating rear handle or full-wrap front handle prevents wrist strain.
Motor amperage for stem hardness. Standard leafy hedges: 3.5 to 4A is adequate. Mature woody boxwood and dense arborvitae: 4A minimum. Thick multi-year growth hedge maintenance: consider 4.5A or step up to a gas hedge trimmer.
Frequently asked questions
How do I get straight hedge cuts with an electric trimmer?+
Use a string guide: stretch a level string along the desired cut line and use it as a visual reference as you sweep the blade along the hedge top. This produces professional-level straight cuts.
What blade gap size do I need for my hedge species?+
Boxwood, privet, and dwarf yew: 5/8 inch is adequate. Arborvitae, hornbeam, and larger ornamental hedges: 3/4 inch. Thick, old formal hedges with mature woody stems: 1 inch or more.
How do I clean hedge trimmer blades after use?+
Wipe blades with a cloth dampened with tool cleaner to remove sap. Apply a light coat of machine oil or blade lubricant spray to prevent rust. Store with the blade guard installed.
Is a corded hedge trimmer better than battery-powered?+
For extended trimming sessions on large hedges, corded trimmers maintain full power throughout. Battery models typically provide 30 to 60 minutes of runtime before needing recharging.
