MDF is a widely used material in woodworking, and a table saw is a versatile tool suitable for various types of cuts. If you want to know if you can cut MDF with a table saw, our woodworking experts got the answers!
In this guide, we’ll share if it’s an appropriate tool along with important safety measures to cut MDF successfully.
Is it Recommended to Cut MDF Using a Table Saw?
Yes, cutting MDF with a table saw is a common and efficient way to work with this material. However, safety precautions are important to prevent injuries and ensure the best possible results.
What Type of Blade to Use For Cutting MDF
A crosscut blade with 80 to 100 teeth or a fine-toothed blade with 60 to 80 teeth can produce clean and smooth cuts on MDF.
Before cutting MDF with a table saw, it’s important to consider several factors to ensure safety and achieve the best possible results:
- Use a blade with a high tooth count and a low hook angle, like the carbide-tipped blade to prevent splintering and tear-out on the material.
- Ensure the blade is sharp to avoid burning and reduce the risk of kickback.
- Wear appropriate protective gear, such as safety glasses, a dust mask, and hearing protection, to prevent injuries and minimize exposure to dust.
- Use proper cutting techniques, such as making multiple shallow passes instead of one deep cut, to avoid binding the blade and causing kickback.
- Use a dust collector or wear a dust mask to minimize exposure to MDF dust, which can be harmful when inhaled.
Factors to Consider When Choosing a Blade To Cut MDF
With the variety of blades available in the market, selecting the appropriate one can be daunting. However, considering certain factors can help you choose the right blade and ensure the success of your project.
Size of the Blade
Generally, a blade with a diameter of 10 inches or more is suitable for cutting MDF sheets up to 1 inch thick.
Using a small blade can cause overheating and result in uneven cuts or burn marks on the material, while a large blade can put excessive strain on the motor and cause the saw to bog down.
Number of Blade’s Teeth
Typically, a blade with 60 to 100 teeth is recommended for MDF cutting. Blades with a large quantity of teeth produce cleaner, smoother cuts on MDF [1], resulting in a better-finished product.
Type of Blade
MDF is a dense and uniform material that requires a blade with teeth designed to make smooth and clean cuts. Choosing the right blade type not only ensures the quality of the cut but also prolongs the life of the blade.
Several blade types are available for table saws that effectively cut MDF.
Type of Blade | Number of Teeth | Characteristics |
Crosscut blade | 60 – 100 |
|
ATB(Alternate Top Bevel) blade | 60 – 100 |
|
Composite blade | 40 -100 |
|
Combination blade | 24 – 50 |

How To Cut MDF Using a Table Saw
You can cut MDF on a table saw using two main methods: crosscutting and rip-cutting. Before using a table saw to make rip cuts or crosscuts on MDF, it’s important to follow these safety precautions:
- Wear appropriate safety gear, including safety glasses, ear protection, and a dust mask to protect against airborne dust.
- Ensure the saw blade is properly installed and tightened.
- Adjust the blade height and fence to the correct position for the desired cut.
- Ensure the saw is properly grounded and there are no exposed wires.
- Keep your hands away from the blade at all times, using a push stick or push block to guide the board through the saw.
- Use a feather board to maintain a flat MDF board against the table and fence.
- Do not stand directly behind the blade, as kickback can occur.
- Keep the work area clean and free of any debris that may cause slips or falls.
How To Rip-Cut MDF Using a Table Saw
Rip cutting is when you cut the MDF board parallel to the grain, ideal for creating longer pieces, resulting in a rougher and less refined edge. Here are the steps for using a table saw for rip-cutting MDF:
- Ensure that the saw blade is suitable for ripping MDF and is sharp before adjusting the blade height so it is just over the MDF board’s height. Next, set the rip fence parallel to the blade and adjust its distance from the blade according to the preferred width of the rip cut.
- Measure and mark the MDF board where the rip cut needs to be made by using a straightedge to draw a straight line along the length of the board to guide the saw.
- Ensure the saw’s safety features, including the blade guard and anti-kickback pawls, are in place and functioning properly. Wear appropriate safety gear, such as safety glasses, ear protection, and a dust mask.
- Turn on the saw and slowly feed the MDF board into the blade while you keep the board pressed firmly against the rip barrier, but avoid pushing it too hard, which can cause kickback. You can use a device such as a push stick or push block to keep your hands safe from the blade.
- Once the cut is complete, turn off the saw and remove the board. Inspect the cut for any rough edges or splinters that need to be sanded down.
How To Crosscut MDF Using a Table Saw
Alternatively, crosscutting involves cutting the MDF board at a right angle to the grain, which is best suited for producing shorter pieces, resulting in a neater and more refined edge.
Below are the steps for using a table saw to crosscut MDF:
- Check that the saw blade is appropriate for crosscutting MDF and is sharp before you adjust the height of the blade to just slightly higher than the MDF board. Then, set the miter gauge to the desired angle or keep it at 90 degrees for a straight cut.
- Measure and mark where the crosscut needs to be made on the MDF board, ensuring that it is perpendicular to the edge.
- Ensure that the saw’s safety features, such as the blade guard and anti-kickback pawls, are functioning correctly and that you are wearing the necessary safety equipment, such as safety glasses, ear protection, and a dust mask.
- Start the saw and gradually feed the MDF board into the blade while keeping it securely against the miter gauge, taking care not to push too hard to avoid kickback. Use a push stick or push block to prevent your hands from getting too close to the blade.
- Once the cut is complete, turn off the saw, remove the board, and inspect the cut for any rough edges or splinters that need to be smoothed out with sandpaper.
Alternative Woodworking Tools For Cutting MDF
In addition to a table saw MDF can be cut using several other woodworking tools. These include:
- Circular saw
- Jigsaw
- Router
- Oscillating multi-tool
FAQ
What is the best way to cut MDF?
The best way to cut MDF depends on the project and available tools. However, a table saw is the most efficient and accurate way to cut MDF, especially for long, straight cuts. But you can use a circular saw or jigsaw for smaller projects or when portability is important.
Conclusion
By taking the necessary safety precautions, you can cut MDF with a table saw effectively. Choosing the appropriate blade type, tooth count, and saw size can ensure precise and tidy cuts.
With the correct tools and safety measures in place, cutting MDF with a table saw can be a straightforward process for professionals and do-it-yourself enthusiasts alike.
