What Is a Drywall Cut Out Tool and How Does It Work?
A drywall cut out tool uses a small-diameter helical or spiral bit — typically with a 1/8-inch shank — that spins at high RPM and plunges directly through the drywall panel. Both tools use the same 1/8-in. helical bits that guide the cut by riding on whatever you're cutting out.The smooth, unfluted tip of the bit rides along the edge of an electrical box, light can, or window jamb, allowing the tool to follow the outline of the object without measuring or marking. A specially designed router bit cuts through the drywall as it follows along the edge of an electrical box or a heat-duct opening. Cutting openings with a router requires less accurate measurements than does cutting with a saw, because you need to find only one edge and follow it around.
This "hang first, cut second" workflow is why professional drywall crews rely on cut out tools: you screw up the panel, plunge the bit near your target, and route around it in seconds — no tape measure, no square, no pencil lines.
Do You Need a Drywall Cut Out Tool?
A cut out tool is worth it if you are:
- Hanging multiple sheets and each has electrical boxes, light switches, or outlet openings to cut
- An electrician or low-voltage installer adding old-work boxes to finished walls
- Cutting openings for recessed lights (can lights), HVAC registers, or access panels
- Working overhead on ceilings where measuring and marking is awkward and slow
You can probably skip it if you are:
- Patching a single hole or cutting one outlet opening — a jab saw or utility knife works fine for that
- Doing demolition rather than precise new-work cutouts
- Only making straight cuts to size sheets — a utility knife with a T-square is faster for that job
Drywall Cut Out Tool vs. Oscillating Tool vs. Jab Saw
One of the most common questions is whether you really need a dedicated cut out tool, or if an oscillating multi-tool or a jab saw can handle the same job. Here's how they compare for the specific task of cutting openings in drywall:
| Task | Drywall cut out tool | Oscillating multi-tool | Jab saw |
|---|---|---|---|
| Outlets & electrical boxes | Fastest for “hang then cut” tracing | Slower (mark first), but controlled | Works, slow & tiring |
| Small patch openings | Fast but dusty | Great control | Fine for 1–2 holes |
| Accuracy / tight fit | Excellent when tracing edges | Good with careful marking | Depends on hand skill |
| Dust | More dust | Usually less | Low (no power) |
What to Look for in a Cordless Drywall Cut Out Tool
When shopping for a cordless drywall cut out tool, these are the features that matter most on the jobsite:
RPM and cutting speed. Most drywall cut out tools operate between 26,000 and 30,000 RPM. Higher RPM generally means smoother cuts with less paper tearing.
Depth adjustment. A specialized depth guide ensures uniform cutting depth and consistent engagement with the bit's cutting edge.You want the bit to extend only about 1/8 inch past the back of the drywall.
Collet size. Look for dual collet compatibility (1/8-inch and 1/4-inch) so you can use standard drywall spiral bits as well as larger shank bits for wood, plywood, or tile backer board.
Weight and ergonomics. A compact, lightweight body (under 2.5 lbs) and a comfortable grip make a real difference across a full day of hanging.
Battery platform. A 20V battery platform means your cut out tool can share batteries with your screw gun, drill, sander, and other cordless tools — fewer chargers, lower total cost.
LED work light. An integrated LED illuminates the cut line, which matters in unfinished spaces with poor lighting (which is most of them).

FAQs
Can I use a drywall cut out tool on cement board or plywood?
Yes—with the right bit. Drywall spiral bits are for gypsum board. For cement board, use a carbide bit; for plywood/wood, use a suitable multipurpose/wood-rated bit and the correct collet size.
What direction should I cut around an electrical box?
With most spiral bits, one direction tends to “pull” the bit toward the box edge while the opposite direction can push it away and overcut. Tip: do a quick test on scrap, then trace the box in the direction that keeps the tool riding the edge smoothly with light pressure.
How do I avoid damaging wires in electrical boxes?
- Turn off power to the circuit before cutting
- Set depth shallow (just enough to clear the drywall)
- Keep pressure light and let the bit do the work
Is a cordless drywall cut out tool powerful enough?
For typical drywall (including common 1/2" and 5/8"), modern cordless models are plenty capable. The main advantage is mobility—no cord management, especially on ceilings and remodel sites.
What bits do I need for outlet cutouts?
A standard 1/8" drywall spiral bit covers most outlet/switch box cutouts. Keep spares—sharp bits cut cleaner and faster.
