Categories : tools
SKU : WOR-TOO-078
The DEWALT DCS551B is a 20V MAX drywall cut-out tool designed for fast, clean cutouts in drywall, acoustical ceiling tile, plywood, and similar materials. Its 26,000 rpm motor delivers quick plunge cuts, while the tool-free bit change system lets you swap bits in seconds without a wrench. A bright LED light illuminates the work area, and the dust-sealed switch resists drywall dust for longer tool life.
The high-speed motor, combined with a narrow nose, gives you good visibility and control around outlets, switches, and other cutouts. Because this is a bare tool, you pair it with any DEWALT 20V MAX battery and charger you already own. It fits confidently in a tool bag and is a go-to for drywall finishers, framers, and remodelers.
Use a sharp spiral bit for clean edges in drywall and ceiling tile. Keep the tool moving at a steady pace to avoid burning the bit. The dust-sealed switch and sealed body help the tool hold up to jobsite dust. For deeper cuts, adjust the depth ring to the material thickness. Always wear eye protection and a dust mask when cutting.

Drywall cutout is one of those tasks that separates the pros from the amateurs. The DEWALT DCS551B makes it easier with a high-speed motor, tool-free bit changes, and a light that shows exactly where you're cutting. The compact body fits well in hand, and the sealed switch resists the gypsum dust that kills lesser tools.
Pair this tool with a carbide spiral bit. Spiral bits clear chips away from the cut and produce a smooth edge. Feed the tool gently; don't force it. For thin drywall, you can complete the cut in one fast pass.
If you already own DEWALT 20V MAX tools, the DCS551B is a smart add-on. It runs on the same batteries and has no cord to manage. You can take it up a ladder or into a crawl space without dragging a cord behind you.
No, this is a bare tool. It requires a DEWALT 20V MAX battery and charger, which are sold separately.
It is designed for drywall, acoustical ceiling tiles, plywood, and similar soft materials. Use a carbide spiral bit for best results.
The bit change is tool-free: pull the chuck sleeve back, insert the new bit, and release the sleeve. No wrenches required.
Any DEWALT 20V MAX battery works. Runtime will depend on the battery amp-hour rating; higher Ah gives longer runtime.
Yes, the narrow nose and LED light make it very accurate for cutting out electrical boxes and other openings in drywall.












Great cutter.
Cuts drywall quickly. The LED light is helpful.
I'm a drywall finisher. This tool has made my work so much faster. The 26,000 rpm makes clean cuts. The bit changes are tool-free and quick. The LED is a great addition. It's a must-have for any drywaller.
It's light and easy to use. Cuts precise holes.
This cut-out tool is awesome. It cuts circles for outlets perfectly. The depth adjustment is easy. I've used it on multiple jobs. No dust cloud because I connect a vac.
I bought this for my son who is an electrician. He says it works well. It's a bit loud but okay.
It works but the battery drains fast. I guess that's expected.
Great for cutting drywall. The bit stays sharp. I like the LED light. Very convenient.
I've been in construction for 45 years. This is the best cut-out tool I've used. It's powerful and precise. The tool-less bit change is a lifesaver. It's well built. I recommend it to everyone.
No issues. Does exactly what I need.
It's a good tool. The LED could be brighter.
I use it for ceiling tile work. It cuts cleanly and quickly. The motor doesn't bog down. The handle is comfortable. I've had no problems. Highly satisfied.
