Only DeWalt 20V MAX pole heads, the matching extension pole, and batteries built for the DCPH820 system count as safe attachments for this pole hedge trimmer.
Owning a 20V DeWalt pole hedge trimmer solves the ladder problem on tall hedges. Sooner or later, though, every owner wonders what attachments work with the 20V DeWalt pole hedge trimmer and which accessories should stay far away from the tool.
What Attachments Work With The 20V DeWalt Pole Hedge Trimmer? Compatibility Basics
DeWalt treats the 20V pole hedge trimmer as part of a small family of tools, not as a universal power head. The list of true attachments is short, yet each piece is built around the same locking joint and 20V MAX battery platform.
Attachments that work with the 20V DeWalt pole hedge trimmer fall into four main groups:
- The DCPH820BH pole hedge trimmer head that ships with many kits and is sold as a replacement.
- The DCPS620 20V MAX pole saw system that shares hardware with the hedge trimmer head in combo kits.
- The N611762 three foot extension pole that adds reach to both the DCPH820 and DCPS620 tools.
- DeWalt 20V MAX and compatible FLEXVOLT batteries that power the system.
The first table below sums up how each of these pieces relates to the DCPH820 pole hedge trimmer.
| Attachment Or Accessory | Works With 20V Pole Hedge Trimmer? | Main Use |
|---|---|---|
| DCPH820BH Pole Hedge Trimmer Head | Yes, direct fit on DCPH820 pole | Replacement or spare hedge trimmer head for hedges and shrubs |
| DCPH820 Complete Pole Hedge Trimmer Body | Base tool that holds the head | Provides motor, controls, and pole sections |
| DCPS620 20V MAX Pole Saw Head | Shares combo kit with DCPH820 | Limbing and pruning branches when used on a compatible pole |
| N611762 Three Foot Extension Pole | Yes, adds reach to DCPH820 and DCPS620 | Gives extra reach for tall hedges and tree limbs |
| 20V MAX DeWalt Battery Packs | Yes, standard power source | Powers the hedge trimmer and other 20V MAX tools |
| DeWalt FLEXVOLT 20V Or 20V/60V Packs | Yes, compatible with 20V MAX tools | Longer runtime for extended trimming sessions |
| 60V Universal Attachments (DWOAS Series) | No, built for 60V attachment capable power heads | Edger, string trimmer, blower, and other tools for 60V bases |
How The 20V DeWalt Pole Hedge Trimmer System Fits Together
The 20V MAX pole hedge trimmer sold as DCPH820B or DCPH820M1 ships as a complete pole tool. You get a back end with motor and controls, pole sections, a shoulder strap, and a hedge trimmer head with a 22 inch blade.
DeWalt lists this tool as a 20V MAX outdoor product with a seven position, 180 degree articulating head and a one inch cutting gap for branches. Official product pages describe the pole hedge trimmer head as the standard cutting attachment in this system.
The head can be removed for service or replacement, which is where the DCPH820BH part number matters. That replacement head keeps the same 22 inch dual action blade, one inch capacity, and articulating joint, and it locks onto both the DCPH820 pole hedge trimmer and the DCPS620 pole saw pole section. DeWalt lists this shared compatibility clearly.
Attachments For The 20V DeWalt Pole Hedge Trimmer That Do Work
DCPH820BH Replacement Pole Hedge Trimmer Head
The direct answer to the compatibility question starts with the DCPH820BH hedge trimmer head. It is built as a spare or replacement for the head that ships in DCPH820 kits. Owners use it when blades are damaged, when a spare head with a sharp blade saves time, or when they own both the pole saw and the pole hedge trimmer and want to move heads between poles.
N611762 Three Foot Extension Pole
The standout reach accessory in this system is the N611762 three foot extension pole. Retailers describe it as an extension built for DCPS620 and DCPH820 tools, and DeWalt names the same use. Only one extension can sit in the middle at a time, so you add three feet of reach, not six or nine, which keeps the tool manageable.
DCPS620 Pole Saw Head And Combo Kits
Many owners first meet the DCPS620 pole saw head in the DCKO86M1 combo kit, which bundles a 20V MAX pole saw and the DCPH820 pole hedge trimmer head along with one extension pole, battery, charger, and accessories. Combo kit listings show how DeWalt expects the system to work: you swap between a hedge trimmer head and a pole saw head so the same style of tool can prune trees and shape hedges during the same visit.
20V MAX And FLEXVOLT Batteries
Battery packs count as attachments too, and they shape how long you can work between charges. Any standard 20V MAX DeWalt lithium ion pack with the slide style rail fits the DCPH820 pole hedge trimmer. DeWalt also lets FLEXVOLT batteries drop into 20V MAX tools, so a 20V or 20V or 60V FLEXVOLT pack can power the same hedge trimmer. DeWalt notes this cross use on hedge trimmer pages.
Attachments That Do Not Work With The 20V DeWalt Pole Hedge Trimmer
Online listings for DeWalt attachments can look confusing, because some parts share the same yellow and black branding but belong to a different system. To keep your hedge trimmer safe, you need to know which series does not connect to the DCPH820 pole.
60V MAX Universal Attachment System
DeWalt runs a separate 60V MAX universal attachment lineup built around string trimmers and edgers that carry an attachment capable label. Official support pages list power heads like DCST972 and DCED472 along with pole saw, hedge trimmer, blower, and edger attachments under DWOAS part numbers. DeWalt presents this group as a 60V system.
The 20V DCPH820 pole hedge trimmer is not described as attachment capable in those guides. That means the DWOAS series attachments are not designed to lock onto the 20V pole hedge trimmer, even if the cutting head looks similar at first glance.
Third Party Pole Attachments
Some third party brands sell pole saw, hedge trimmer, or brush attachments that claim to fit DeWalt tools. Many of these are built for the 60V universal system or for generic gas powered split shafts, and the locking shapes and drive shafts often differ from what you find on the 20V DCPH820 pole hedge trimmer.
Because of that mismatch, attaching non DeWalt heads directly to the DCPH820 pole hedge trimmer can strip the drive connection, jam the tool, or defeat built in safety features. Third party battery packs that follow DeWalt rail dimensions usually work with 20V MAX tools, but pole attachments that hang off the front of the tool deserve much more care.
| Attachment Category | Use On 20V Pole Hedge Trimmer? | Notes |
|---|---|---|
| DCPH820BH Hedge Trimmer Head | Yes | Standard and replacement head for trimming hedges |
| DCPS620 Pole Saw Head | Only in matching combo or pole system | Pairs with a compatible pole saw style base |
| N611762 Extension Pole | Yes | Adds reach, one extension at a time |
| DWOAS Universal Attachments | No | Built for 60V attachment capable power heads |
| Third Party Split Shaft Heads | No | Locking shapes and drive sizes do not match |
| 20V MAX Battery Packs | Yes | Standard slide batteries for the tool |
| FLEXVOLT Battery Packs | Yes | Can power 20V MAX tools and extend runtime |
Choosing And Using Attachments Safely
The hedge trimmer head that ships with the DCPH820 already covers many yard jobs. It cuts dense shrubs, shapes privacy hedges, and reaches the tops of bushes along fences. If your yard care focuses on those tasks, a fresh blade on the stock head and a spare DCPH820BH head on the shelf may be all you ever need.
Add the extension pole when hedge tops sit several feet over your head and you still want to work from the ground. Add the DCPS620 pole saw system when you often cut limbs thicker than an inch where the hedge trimmer blade stalls. Use battery size to control how long you can work before charging.
Whenever you change an attachment on the 20V DeWalt pole hedge trimmer, remove the battery pack first. Lay the tool on a flat surface, release the locking collar, and pull the head straight off the pole section rather than twisting at an angle. When you slide a head back on, watch the drive shaft and grooves so they line up before you tighten the collar.
Clean blades after every trimming session. Brush off leaves and sap, wipe down the hedge trimmer head, and store it in the sheath that ships with the tool. Check pole sections for dents or cracks, and make sure locking collars still move smoothly and clamp down without slipping.
Practical Takeaways For Your 20V DeWalt Pole Hedge Trimmer
When you look past the long line of DeWalt outdoor attachments on store shelves, the answer to what attachments work with the 20V DeWalt pole hedge trimmer turns out to be straightforward. The DCPH820BH hedge trimmer head, the matching pole saw system, the N611762 extension pole, and the family of 20V MAX and FLEXVOLT batteries all sit inside the intended system.
Everything else either belongs to a 60V universal platform or to another brand. Those parts may share a paint color or a rough shape, yet they are not intended for the DCPH820 pole hedge trimmer. If you stay inside the confirmed compatibility list and care for the heads and poles you already own, that 20V DeWalt pole hedge trimmer will stay ready for hedge trimming, shaping, and light tree work for many seasons.
