Can a dado blade be used for plywood?
Hey there, woodworking enthusiasts! As a supplier of Saw Blades for Plywood, I often get asked a bunch of questions about which blades work best for different tasks. One question that pops up quite a bit is, "Can a dado blade be used for plywood?" Let's dig into this topic and find out the ins and outs.
First off, let's talk a bit about what a dado blade is. A dado blade is a special type of saw blade that's designed to make wide, flat-bottomed cuts, usually for creating rabbets, dados, and grooves in wood. These blades typically consist of a set of multiple blades that can be adjusted to vary the width of the cut. They're super handy when you're building cabinets, shelves, or other furniture pieces where you need to join pieces of wood together using these types of joints.
Now, plywood is a different beast. It's made up of thin layers of wood veneer that are glued together at right angles to each other. This construction gives plywood its strength and stability, but it also means that cutting it requires a bit of finesse. The layers of veneer can splinter or tear if you're not using the right blade, which can ruin your project and make it look less than professional.
So, can a dado blade be used for plywood? The short answer is yes, but with some important considerations.
Pros of Using a Dado Blade for Plywood
One of the main advantages of using a dado blade on plywood is that it can create clean, precise grooves and dados. If you're building a cabinet or a bookshelf and you need to insert shelves into grooves in the sides, a dado blade can make those grooves with a nice, flat bottom and straight sides. This ensures a snug fit for the shelves and a more professional-looking finish.
Another benefit is that dado blades can be adjusted to different widths. This means you can customize the size of the groove or dado to fit the thickness of the plywood or other materials you're using. For example, if you're using 3/4 - inch plywood for your shelves, you can set the dado blade to create a groove that's exactly 3/4 inches wide, ensuring a perfect fit.
Cons of Using a Dado Blade for Plywood
However, there are also some drawbacks to using a dado blade on plywood. One of the biggest issues is the potential for splintering. Because plywood is made up of multiple layers of veneer, the dado blade can cause the veneer to splinter or tear as it cuts through the wood. This is especially true if the blade is dull or if the cutting speed is too fast.
Another problem is that dado blades can be a bit more difficult to use than regular saw blades. They require a special arbor on your saw, and you need to be careful when adjusting the width of the cut to make sure it's accurate. If you're not experienced with using dado blades, it can take some practice to get the hang of it.


Alternatives to Dado Blades for Plywood
If you're worried about splintering or if you're not comfortable using a dado blade, there are some alternatives that you might want to consider.
One option is to use a Thin Kerf Circular Saw Blade. These blades have a narrow kerf (the width of the cut), which means they remove less wood as they cut. This can help reduce splintering and make for a cleaner cut. Thin kerf blades are also more efficient, as they require less power to operate.
Another alternative is to use Gang Saw Blades. Gang saw blades are a set of multiple blades that are stacked together and used to make multiple cuts at the same time. They can be used to create grooves and dados in plywood, and they can be a good option if you need to make a lot of cuts quickly.
If you're mainly doing crosscuts on plywood, a Crosscut Saw Blade might be the way to go. These blades are designed to make smooth, clean cuts across the grain of the wood, which is ideal for cutting plywood to size.
Tips for Using a Dado Blade on Plywood
If you do decide to use a dado blade on plywood, here are some tips to help you get the best results:
- Use a sharp blade: A dull blade is more likely to cause splintering and tear-out. Make sure your dado blade is sharp before you start cutting.
- Set the correct cutting speed: Cutting too fast can cause the blade to overheat and damage the plywood. Follow the manufacturer's recommendations for the cutting speed based on the type of plywood and the size of the blade.
- Support the plywood properly: Make sure the plywood is well-supported on your saw table to prevent it from vibrating or moving during the cut. This can help reduce splintering and ensure a more accurate cut.
- Use a zero-clearance insert: A zero-clearance insert is a piece of material that fits around the blade in the saw table. It helps support the plywood right up to the edge of the blade, which can reduce splintering on the underside of the cut.
