The circular saw is a versatile and powerful tool, but achieving clean, accurate cuts requires the right technique, proper setup, and attention to detail.
This guide will walk you through the process of cutting plywood using a circular saw, providing expert tips and troubleshooting advice along the way. Whether you’re cutting plywood for furniture, cabinets, or another project, these techniques will ensure you get the best results.
Materials and Tools Needed for Cutting Plywood with a Circular Saw
Before starting, make sure you have everything you need. Using the right tools is essential for making accurate cuts and ensuring your safety while working with a circular saw.
1. Circular Saw
A circular saw is the most commonly used tool for cutting plywood. Look for one with a fine-toothed blade that’s specifically designed for wood. For general plywood cutting, a 7-1/4-inch blade is the standard size. If you are working with thicker or tougher plywood, you may want to use a blade with more teeth or a blade designed for fine cuts.
Different saw blades work better with different types of plywood. For example:
- Fine-toothed blades are best for softwood plywood, ensuring smooth cuts with minimal splintering.
- Coarse-toothed blades are ideal for hardwood plywood and can help you make quicker cuts, but may leave a rougher edge.
2. Plywood
The type of plywood you choose will depend on the specifics of your project. Plywood comes in various types, such as hardwood, softwood, or MDF (Medium Density Fiberboard), and the thickness can vary from 1/8-inch to 1-inch or more. For best results, ensure that you are using a high-quality sheet of plywood to minimize the risk of splitting or warping.
3. Measuring Tape or Ruler
A measuring tape or ruler is essential to get precise measurements before cutting the plywood. A reliable measuring tape ensures that your cuts are accurate, which is key for creating components that fit together properly.
4. Pencil or Chalk
A pencil or chalk is needed to mark the cut line on your plywood. Make sure your marks are visible, but not so thick that they’ll interfere with the saw.
5. Clamps
Clamps are crucial for securing the plywood to a work surface, preventing it from shifting as you cut. A sawhorse or sturdy workbench can also provide stability.
6. Safety Gear
Safety should always be a top priority. When using a circular saw, make sure you have the following:
- Safety goggles to protect your eyes from flying debris.
- A dust mask to prevent inhaling fine wood particles.
- Hearing protection to block out the loud noise of the saw.
- Gloves to protect your hands from sharp edges and potential splinters.
7. Woodworking Square (Optional)
A woodworking square can be used to check that your cuts are square and ensure they are perfectly aligned at 90 degrees to the edge of the plywood.

Step-by-Step Guide to Cutting Plywood with a Circular Saw
Now that you have all your materials ready, let’s go through the steps for cutting plywood accurately and safely with a circular saw.
1. Prepare Your Workspace
Clear the Area
Before starting, make sure your workspace is clear of any clutter. A clean area ensures you can move freely and operate the saw safely. Additionally, ensure there is ample lighting so you can see your work clearly.
Secure the Plywood
Place the plywood on a stable surface, like a sawhorse or workbench, and secure it with clamps. If the plywood is large, make sure it is adequately supported on both sides of the cut to avoid bending, which could result in an inaccurate or dangerous cut.
Check the Blade
Before making your cut, make sure your saw blade is clean and sharp. A dull blade will make the cutting process more difficult and can cause splintering, which leads to a rough finish.
2. Measure and Mark the Cut Line
Accurate Measurement
Use a measuring tape to measure and mark the exact location of your cut. Be sure to double-check your measurements to ensure that your cuts will be the correct length. For a precise cut, use a ruler to help guide your measurement and mark the exact point on the plywood.
Mark the Cut
Once you have your measurements in place, use a pencil or chalk to mark a straight, visible cut line on the plywood. Try to keep your markings light but distinct. You’ll be following this line with your saw, so the clearer it is, the better.
Use a Square (Optional)
For perfectly straight, square cuts, particularly for crosscuts, consider using a woodworking square. This will help you check that your line is at a perfect 90-degree angle to the edge of the plywood, ensuring that your cut is accurate.

3. Set the Depth of the Cut
Adjust the Blade Depth
Set the depth of your circular saw blade to just slightly deeper than the thickness of your plywood. This ensures that the blade cuts all the way through the plywood while also minimizing splintering on the underside. Too deep of a cut can put excess strain on the saw, while too shallow of a cut may result in incomplete cuts.
4. Set the Saw’s Speed and Angle (Optional)
Choose the Right Speed
If your circular saw has variable speed settings, choose a speed that matches the thickness of the plywood. Generally, a medium to high speed works well for most plywood cuts. Thicker plywood may require a slower speed to prevent binding and ensure a clean cut.
Adjust the Angle (Optional)
If your project requires angled cuts (e.g., bevel cuts), you can adjust the saw’s base to the desired angle. Most circular saws allow angle adjustments up to 45 degrees. Be sure to lock the angle in place before starting to cut.
5. Cut the Plywood
Position the Saw
Align the saw blade with the marked cut line, ensuring that the base of the saw is flush with the plywood edge. Your saw blade should rest just slightly outside of the cut line, so you don’t cut into the marked area.
Start Cutting
Switch on the saw and let the blade reach full speed before starting the cut. Move the saw slowly and steadily along the cut line, ensuring that the base plate of the saw stays flat against the plywood surface. Allow the saw to do the work—don’t force it through the material.
Follow the Line
Keep the saw steady and follow the marked line closely. Focus on controlling the saw’s movement and guiding it along the path without pushing too hard. The smoother your movements, the cleaner the cut will be.
Minimize Splintering
To minimize splintering, always position the good side of the plywood (the side that will be visible) facing downwards. The saw will cause splintering on the underside, so positioning the better side face down ensures that the imperfections will be less noticeable.
6. Finishing the Cut
Turn Off the Saw
Once you’ve completed the cut, turn off the saw and wait for the blade to come to a complete stop before lifting it away from the plywood. This avoids unnecessary contact with the blade and ensures you don’t accidentally make another cut.
Inspect the Cut
Check the edge of the plywood to ensure it’s smooth and even. If necessary, use sandpaper or a sanding block to smooth any rough edges or splinters. This will give your project a more professional appearance.

Tips and Tricks for Better Cuts
Use Painter’s Tape
Apply painter’s tape along the cut line to reduce splintering. The tape holds the fibers together, creating a cleaner edge and preventing the plywood from chipping, especially on the top side.
Support Large Sheets
When cutting large sheets of plywood, ensure that both sides of the sheet are well supported. Use additional sawhorses or supports to prevent the material from bending or flexing during the cut, which could cause the saw to bind.
Use a Guide Rail
For long, straight cuts, consider using a guide rail or straightedge. This tool helps keep the saw aligned with the cut line and ensures you achieve a straight, professional-quality cut.
Make Multiple Passes
For thicker plywood, rather than trying to cut through the entire thickness in one go, make multiple shallow passes. This reduces strain on the saw and helps ensure a smoother cut.
Troubleshooting Common Issues
Saw Binding
If the saw binds during cutting, check if the blade is dull, the plywood isn’t properly secured, or if you are pushing the saw too fast. Reduce pressure and let the saw cut at a steady pace. Ensure the plywood is properly supported to avoid binding.
Rough Edges
If you notice rough edges, this can be caused by a dull blade or cutting too quickly. Sharpen or replace the blade, and try cutting more slowly for a cleaner finish.
Warping or Bending
To avoid the plywood from warping or bending during the cut, make sure the sheet is well supported on both sides. Use additional supports or clamps to stabilize the plywood, especially when cutting large sheets.

Alternatives to Circular Saws
While circular saws are great for cutting plywood, they aren’t the only option. If you need more precision or smoother cuts, consider using the following alternatives:
- Jigsaw: Ideal for making curved cuts or cutting out intricate shapes.
- Track Saw: For extremely accurate straight cuts on larger sheets of plywood, a track saw is a fantastic option. It provides precision similar to a table saw, with the portability of a circular saw.
