Key Features
Brushless Runtime
The brushless motor gives this drywall sander better runtime, steadier speed, and less maintenance than a brushed setup. That matters when you are sanding long seams and want the tool to stay consistent instead of fading as the job drags on.
Reach Tight Areas
A telescoping shaft and articulating head help the pad stay planted on the wall or ceiling while giving you access to confined spaces and awkward angles. You spend less time fighting the tool and more time actually flattening compound.
Cleaner Sanding Setup
The DeWALT DCE800B 20V MAX Cordless Drywall Sander connects tool-free to compatible DEWALT dust extractors through AirLock and can pair through Wireless Tool Control. That means faster setup and a cleaner room when drywall dust is the part everyone hates.
Overview
The DeWALT DCE800B 20V MAX Cordless Drywall Sander is a battery-powered drywall sander built for sanding joint compound on walls and ceilings with less cord management and easier dust collection. This is a drywall sander designed for finishing drywall surfaces in remodels, new construction, and punch-list work. Model Number: DCE800B. If you want a cordless sanding setup that can move room to room without dragging an extension cord, this is the tool DeWALT built for that job.
The core of the tool is a brushless motor, and that matters for more than just spec-sheet talk. A brushless setup helps deliver better runtime, improved durability, and more consistent sanding speed while also cutting down on maintenance. DeWALT also gives you a variable speed dial, so you can slow the tool down when you are feathering finish coats and turn it up when you need to move material faster. It has a top speed of 1,200 RPM, giving you controlled material removal instead of an all-or-nothing feel.
Where this cordless drywall sander really earns its keep is reach and surface contact. The telescoping shaft helps you work into large spaces and awkward spots without constantly repositioning ladders or body position, while the articulating head helps the sanding pad stay in contact with the surface at different angles. That combination is useful on ceilings, tall walls, stairwells, and tight corners where a fixed-head sander can feel clumsy. Balanced weight distribution is also called out by DeWALT, which helps reduce fatigue during longer sanding sessions.
Dust control is a big part of whether a drywall sanding tool is worth owning, and DeWALT clearly built this one around extraction. The DCE800B uses a quick, secure, tool-free AirLock connection for compatible DEWALT dust extractors. It is also equipped with Wireless Tool Control for pairing with compatible extractors, so the vacuum side of the setup can work more seamlessly with the tool. For drywall finishing, that means less airborne dust, less cleanup, and a better chance of keeping occupied spaces under control during renovation work.
The platform story is straightforward. This is a 20V MAX cordless tool-only model, so the battery and charger are sold separately. DeWALT states about 30 minutes of runtime when used with the DCB205 battery, which gives buyers a realistic reference point for planning work. If you are already on the DeWALT 20V MAX system, that makes this tool easier to add without buying into another battery line.
DeWALT also notes compatibility with DWE7801 soft and DWE7802 hard backing pads. That gives you some flexibility in how the sander behaves depending on the finish level and surface you are chasing. For drywall pros, that kind of pad choice can help when moving between aggressive stock removal and more refined finish sanding.
This is not a light-duty hand sander replacement. It is a purpose-built drywall finishing tool for contractors, remodelers, and serious users who want faster sanding, better reach, and real dust-management options. If you only patch a wall once a year, this is more tool than you need. If drywall work shows up regularly and you are tired of cords, dust, and inconsistent sanding, the DCE800B makes a lot more sense.
Long Reach Without the Cord
This cordless drywall sander is built to cover wall and ceiling work without the constant hassle of managing a cord behind you. The telescoping shaft helps you reach farther while the articulating head keeps the pad tracking the surface instead of skipping across it.

Built to Work With Dust Extraction
Drywall sanding gets messy fast, so DeWALT gave this tool a setup that works with extraction instead of treating it like an afterthought. AirLock gives you a quick connection to compatible DEWALT dust extractors, and Wireless Tool Control adds another layer of convenience when paired with a compatible extractor.
