What is plywood?
Plywood is a versatile material that is commonly used in construction and woodworking projects. It is made by gluing together multiple layers, known as plies, of thin wood veneers. The grain of each veneer is typically rotated perpendicular to the adjacent layers, which helps increase the strength and stability of the plywood.
Plywood comes in various thicknesses, sizes, and grades, making it suitable for a wide range of applications. It is known for its strength, durability, and resistance to warping, making it a popular choice for both structural and decorative purposes.
The layers of wood veneers used in plywood are usually sourced from different types of hardwoods or softwoods. Hardwood plywood is made from hardwoods such as birch, maple, or oak, while softwood plywood is made from softwoods like pine or cedar. The type of wood used for the veneers can affect the appearance, strength, and price of the plywood.
One of the main advantages of plywood is its ability to resist splitting and cracking. The cross-grain construction of plywood makes it less likely to splinter compared to solid wood. This makes plywood a great choice for projects that require a stable and splinter-free surface.
Types of Plywood:
There are several types of plywood available, each with its own unique characteristics and uses:
- Structural plywood: This type of plywood is specifically designed for use in construction and is often used for flooring, walls, and roofs.
- Marine plywood: Marine plywood is specially treated to resist rotting and is commonly used in boats and other outdoor applications that are exposed to moisture.

Choosing the right circular saw for cutting plywood
When it comes to cutting plywood sheets with a circular saw, choosing the right tool is essential for achieving clean and accurate cuts. Here are some factors to consider when selecting a circular saw for cutting plywood:
Type of Circular Saw
There are two main types of circular saws that are commonly used for cutting plywood: sidewinder saws and worm drive saws. Sidewinder saws are lighter and more compact, making them easier to maneuver and control. They are generally a good choice for cutting plywood sheets that are 1 inch or thinner. On the other hand, worm drive saws have more power and torque, making them better suited for cutting thicker plywood sheets. They are also more durable and can withstand heavy-duty use.
Saw Blade
Another important factor to consider is the type of saw blade that you will be using. For cutting plywood, it is recommended to use a carbide-tipped saw blade with a high tooth count. The high tooth count will result in smoother cuts and reduce the risk of splintering. It is also important to ensure that the saw blade is sharp and in good condition before starting your cutting project.
| Aspect | Consideration |
|---|---|
| Saw Size | Choose a circular saw with an appropriate blade size that can accommodate the thickness of the plywood sheets you will be cutting. |
| Power Source | You can choose between corded circular saws and cordless circular saws. Corded saws generally provide more power, while cordless saws offer greater mobility and convenience. |
| Bevel Capacity | If you anticipate the need to make beveled cuts, consider a circular saw with a bevel capacity that allows for angled cuts. |
| Ergonomics | Look for a circular saw with comfortable grips and ergonomic features that will reduce fatigue during extended cutting sessions. |
Overall, choosing the right circular saw for cutting plywood involves considering the saw type, blade type, saw size, power source, bevel capacity, and ergonomics. By selecting the appropriate saw for your specific needs, you can ensure cleaner, more accurate cuts when working with plywood sheets.
Consider the power and blade size
When cutting plywood sheets with a circular saw, it is important to consider the power of the saw and the size of the blade. Both of these factors can greatly affect the quality and efficiency of your cuts.
The power of a circular saw is typically measured in amps. Higher amp ratings usually indicate a more powerful motor, which can make it easier to cut through thick plywood sheets. If you are planning to cut through large or dense plywood, you may want to consider using a circular saw with a higher amp rating.
In addition to power, the size of the blade also plays a crucial role in cutting plywood. Circular saw blades come in various sizes, typically ranging from 6 to 10 inches in diameter. The larger the blade, the deeper the cut it can make. For cutting plywood sheets, it is generally recommended to use a blade size between 7 and 8 inches.
| Power | Blade Size | Suggested Use |
|---|---|---|
| 10-12 amp | 7-8 inches | General plywood cutting |
| 12-15 amp | 8-10 inches | Cutting thick or dense plywood sheets |
Keep in mind that using a circular saw with insufficient power or an inadequate blade size can result in poor quality cuts and can even damage the plywood. It is important to choose a saw with adequate power and the right blade size for the job at hand.
Look for additional features
When selecting a circular saw for cutting plywood sheets, it is worth looking for additional features that can make your cutting tasks easier and more efficient.
One important feature to consider is an integrated dust collection system. Cutting plywood produces a lot of sawdust, which can be messy and obstruct your line of sight. With a built-in dust collection system, the saw will capture the sawdust as you cut, keeping your work area cleaner and improving visibility.
Another useful feature is a laser guide. This feature projects a laser beam onto the material being cut, helping you achieve more accurate and precise cuts. The laser guide allows you to follow a straight line with ease, resulting in cleaner and more professional-looking cuts.
Some circular saws also come with an electric brake. This feature can greatly improve safety by quickly stopping the blade’s rotation when you release the trigger. An electric brake not only reduces the chance of accidental injury but also allows you to make faster repetitive cuts.
Additionally, consider a saw with an adjustable bevel capacity. This feature allows you to tilt the blade at different angles, making it easier to cut beveled edges or create precise mitre cuts. An adjustable bevel capacity gives you more versatility and flexibility in your woodworking projects.
| Additional Features | Description |
|---|---|
| Integrated dust collection system | Captures sawdust for a cleaner work area |
| Laser guide | Projects a laser beam for more accurate cuts |
| Electric brake | Quickly stops blade rotation for improved safety |
| Adjustable bevel capacity | Tilts blade at different angles for more versatile cuts |
Considering these additional features when choosing a circular saw can enhance your cutting experience and help you achieve better results with plywood sheets.
