How to Cut MDF Board: Laser Cutter & Circular Saw Methods

Cutting MDF can be tricky if you don’t know what you’re doing. This blog post will show you the best ways to cut MDF board so you can achieve clean and accurate cuts every time. We’ll also show you some of the best tools for the job.

Let’s dive in!

MDF Board vs. Plywood

There’s no denying that plywood is one of the most versatile construction materials out there. But what about its lesser-known cousin, MDF board?

While it doesn’t have the same natural strength and durability as plywood, MDF (Medium Density Fiberboard) has its advantages as an engineered wood that make it worth considering for your next project.

For one thing, MDF is much cheaper than plywood. Thanks to its smooth surface and consistent density, it’s also easier to work with.

And because it doesn’t have any grain, MDF is less likely to splinter or crack when cut or drilled.

So which one should you use for your next project? Ultimately, it comes down to personal preference and the job’s specific requirements.

Plywood is the way to go if you need a reliable and sturdy material that can withstand heavy use.

But if you’re looking for a more budget-friendly option that’s still versatile and easy to work with, MDF board could possibly be the better choice.

How to Cut MDF Board with a Circular Saw

Cutting MDF board with a circular saw is one of the best ways to go about it since it reduces the chances of accidentally chipping the MDF. 

Before starting, make sure that your saw blade is sharp. A dull circular saw blade will cause the board to chip and splinter, making it very difficult to get a clean cut.

You should also double-check that the depth of cut is set correctly. If the blade is too deep, it will bind in the board and could cause kickback.

1. Set up your work area.

Cut MDF outside while wearing a dust mask if possible, as the dust can be harmful to breathe. Place the MDF sheet on sawhorses or a stable workbench. Measure and mark the cut line with a pencil.

2. Ready your saw.

Attach a fine-toothed carbide tipped blade to your circular saw. Set the blade depth to half the thickness of the MDF board.When you’re ready to cut, position the board on the saw table. Make sure that your hands are well away from the blade. 

3. Start cutting.

When you start the cut, use a smooth, even motion. Hold the saw steady with both hands and follow the pencil line as you cut. Keep the blade perpendicular to the MDF surface to avoid chipping or splintering. Don’t try to force the blade through the board – let the saw do the work.

4. Finish up.

Use a sanding block or power sander to smooth any rough edges on your MDF board. If you’re using the MDF for a project that requires a clean, finished look, you may want to seal it with a coat of paint or varnish.

How to Laser-Cut MDF Boards

Laser-cutting MDF board is a great way to add a professional touch to your work. With a little practice, you’ll be able to create precise and intricate designs that will impress your friends and family.

Here’s how to laser-cut MDF boards:

1. Prepare your design.

First, you’ll need to create a design or template for your project. If you need to become more experienced in using design software, many online tutorials can help you get started. Once you have your design ready, save it as a PDF or DXF file.

2. Set up your laser cutter.

Before you start cutting, you’ll need to set up your laser cutter according to the manufacturer’s instructions. This includes adjusting the focus and setting the power and speed settings.

3. Load your MDF board.

Once your laser cutter is all set up, it’s time to load your MDF board. Ensure the board is placed securely on the cutting bed and the design is properly aligned.

4. Start cutting!

Now you’re ready to start MDF cutting. Press the start button on your laser cutter and watch as it does its work. Depending on the size and complexity of your design, it may take a few minutes to finish cutting.

5. Remove your project.

Once the cutting is complete, carefully remove your project from the laser cutter. If there are any rough edges, you can use sandpaper to smooth them out. Be sure to remove any dust, especially if you plan to paint the MDF afterward.

Frequently Asked Questions (FAQs)

How do you cut MDF without chipping?

Using a circular saw with a carbide tipped blade will minimize your chances of chipping the MDF. It is important to take your time and work slowly to avoid making any mistakes.

What is the best tool to cut MDF?

For most applications, a simple handheld saw will suffice. However, a power saw may be necessary for more complex cuts or larger pieces. In general, a circular saw or jigsaw works well for cutting MDF. Some woodworkers also find it helpful to use a router or trimming bit to create clean, straight edges.

How thick MDF can a laser cutter cut?

Most laser cutters can generally handle MDF up to about 1/2 inch thick. However, some industrial-grade lasers can cut much thicker MDF.

What type of circular saw blade should I use to cut MDF?

A fine-toothed blade with at least 50 teeth is best for making clean cuts. In addition, it is important to use a blade designed specifically for cutting MDF, such as a carbide tipped blade. These blades have a special coating that helps to prevent the edges from chipping.

Will Lowes cut MDF for You?

Yes. They can also cut lumber, tile, drywall, and more for you to get started on your project immediately.

How much is MDF board?
