Additional steps are outlined in the content below.
So, if you are confused about it, can you cut drywall with a circular saw? Indeed, this is a very impactful tool that shares significant advantages over traditional methods.
1. Can You Cut Drywall with a Circular Saw?
Yes, you can cut drywall with a circular saw effectively. This method provides speed and accuracy, typically surpassing many traditional cutting tools, especially for large and straight cuts. But your success depends on good technique, the right blade, and safety steps.
Advantages of Using a Circular Saw for Drywall
Fast and Efficient
A circular saw cuts through drywall much faster than utility knives. This is especially true for thick sheets. This speed advantage is crucial because it enables the handling of large projects or meeting tight deadlines. You will find that professional contractors often prefer this method for production cutting.
Straight and Clean Cuts
The guided cutting action produces remarkably straight edges with minimal cleanup required. You can also achieve beveled cuts for specialty applications, such as creating angled joints or fitting drywall around corners. To make beveled cuts, adjust the angle of your circular saw's base plate accordingly. This precision eliminates the need for extensive sanding along cut edges.
Versatile
Circular saws handle many cut types. For instance, this includes straight cuts, beveled edges, and partial cuts. Moreover, they also work on both rough framing cuts and finish work. Ultimately, this versatility makes them ideal for complex installations. It helps when you need custom fits.
Necessary Precautions and Tips When Using a Circular Saw for Drywall
Use the Right Blade
You should install a fine-tooth carbide blade specifically designed for drywall cutting. Choose blades with 40-60 teeth for the smoothest cuts, such as the Freud D0760A and DeWalt DW3128P5. Avoid using standard wood-cutting blades, as they typically create rough, chipped edges and excessive dust. However, specialized blades designed for both wood and drywall may also be suitable. Avoid masonry blades entirely, as they'll tear through drywall messily.
Set the Depth Correctly
You must adjust the blade depth. It should extend just 1/8 to 1/4 inch beyond the drywall thickness. For standard 1/2-inch drywall, the best setting is to set your blade to 3/4 inch deep. For 5/8-inch fire-rated drywall, adjust to 7/8-inch.
Furthermore, this prevents damage to surfaces underneath, such as flooring or electrical components, and ensures a complete cut through the drywall, which is essential for a clean installation.
You should check depth settings before each cut, especially when switching between different drywall thicknesses.
Support the Material
You need to ensure the drywall sheet is well-supported on both sides of the cut line. Use heavy-duty sawhorses rated for at least 1,000 pounds for optimal support. If using two 2x4 boards on sawhorses, ensure they are securely positioned and adequately supported to prevent sagging and instability during cutting.
Moreover, you should position supports no more than 16 inches from the cut line to prevent sagging. For large 4x12 sheets, use three support points. Unsupported sheets often crack along the gypsum core or break completely, wasting expensive materials and resources.
Safety Gear
You must always wear ANSI Z87.1-rated safety glasses and an N95 or P100 dust mask. Drywall cutting generates crystalline silica dust that can cause silicosis if inhaled over prolonged periods. 3M's 8511 respirator, which is N95-rated, provides effective protection against drywall dust and helps minimize respiratory irritation.
Furthermore, consider wearing hearing protection when using power tools, such as foam earplugs (32 NRR rating) or earmuffs, for extended cutting sessions.
Guidance and Marking
Use a straight edge or chalk line to mark the cuts. If you clamp a guide board along the cut line, you'll ensure perfectly straight results. Accurate marking prevents costly mistakes you might regret later. To ensure precision, consider using a straightedge for longer cuts and a chalk line for marking straight lines over larger areas.

How do I cut drywall without creating too much dust?
The best trick is hooking up your circular saw to a vacuum cleaner. Most newer saws have a dust port built in, such as the ONEVAN 125mm Brushless Cordless Saw. Connect a shop vac equipped with a HEPA filter to the dust port of your circular saw, if available, to significantly reduce dust during cutting. If your saw lacks a dust port, consider using a handheld vacuum nearby to catch dust as you cut. Also helps to crack open some windows or get a fan going.
What's the best way to cut curves in drywall?
You'll want a jigsaw for curves. Circular saws are great for straight cuts, but they can't handle curves worth a damn. Something like the ONEVAN cordless jigsaw will let you make smooth curves and cut around things like outlet boxes without much fuss.
How do I keep my cordless circular saw from overheating when cutting drywall?
Don't push it too hard - let the blade do its thing. Keep a steady pace instead of trying to rush through. When you overwork the motor, it heats up quickly. Ensure your blade is both sharp and clean. A dull blade makes everything work harder than it needs to. Brushless motors are worth considering since they run cooler and last longer.
Is it safe to cut drywall indoors with a cordless circular saw?
Cutting drywall indoors requires careful attention to safety precautions. Get some air moving with windows or fans. Wear an N95 or P100 mask - that gypsum dust isn't something you want in your lungs. Safety glasses are a no-brainer, too. Keep your work area clean to prevent tripping hazards.
What's the best way to deal with drywall dust?
Use a shop vac with a HEPA filter while you're cutting. When you're done, vacuum everything thoroughly. Don't sweep - that just kicks dust back into the air. Use damp rags to wipe down surfaces afterward. Bag up the dust and seal it before disposing of it. Keep that dust mask on during cleanup as well.
