Why Doesn’t My Table Saw Cut Square
If you’re a woodworker or someone who enjoys DIY projects, you know how frustrating it can be when your table saw doesn’t cut square. You measure twice, cut once, but somehow the angle is still off. So, why does this happen? There are a few common reasons why your table saw may not be cutting square, and understanding them can help you troubleshoot and fix the issue.
Blade Alignment: One of the main culprits behind an inaccurate table saw cut is blade misalignment. Over time, the blade may become tilted or improperly aligned, leading to angled cuts. To check the alignment, you can use a combination square or a specialized tool called a dial indicator. Adjusting the blade alignment is a relatively simple fix that can greatly improve the accuracy of your cuts.
Fence Issues: Another reason for a lack of squareness in your cuts could be problems with the fence. The fence is the guide that runs parallel to the blade and helps control the position of the workpiece. If the fence is not properly aligned or is not firmly locked in place, it can cause the wood to veer off at an angle during the cut. Make sure to regularly check and adjust the fence to ensure it is perpendicular to the blade.
Worn or Dull Blade: A worn or dull blade can also contribute to inaccurate cuts. As the blade loses its sharpness, it may start to deflect or wander from the intended path, resulting in angled cuts. Regularly inspect the condition of your blade and replace it when necessary. Using a high-quality, sharp blade is essential for achieving square cuts.
In conclusion, if your table saw is not cutting square, it could be due to blade misalignment, fence issues, or a worn/dull blade. By addressing these common issues and ensuring proper alignment and blade condition, you can improve the accuracy and precision of your table saw cuts.
What is a Table Saw?
A table saw is a versatile woodworking tool commonly used in woodworking shops and construction sites. It consists of a circular saw blade mounted on an arbor, powered by an electric motor. The blade protrudes through the table’s surface, allowing it to cut through various materials with precision.

Issues with the table or miter gauge can also contribute to inaccurate cuts. If the table is not flat or the miter gauge is not aligned properly, it can affect the stability and precision of the cuts. Check and adjust the table and miter gauge to ensure they are in good condition and properly aligned.
5. Operator Error
Finally, operator error can also play a role in producing non-square cuts. Improper technique, such as applying uneven pressure or not maintaining a steady feed rate, can result in inaccuracies. Taking the time to learn and practice proper cutting techniques can help minimize errors.
By addressing these potential causes of inaccuracy, you can improve the squareness of your table saw cuts and achieve more precise results.
Inadequate Setup
A common reason for a table saw not cutting square is an inadequate setup. When setting up a table saw, there are several key factors that need to be addressed in order to ensure accurate and square cuts.
Fence Alignment: The fence of a table saw is responsible for guiding the workpiece during the cut. If the fence is not properly aligned, it can result in angled cuts. To ensure the fence is aligned correctly, use a square to check that it is parallel to the saw blade.
Blade Alignment: The alignment of the saw blade is crucial for square cuts. If the blade is not perfectly parallel to the table and fence, it can cause the workpiece to be cut at an angle. Adjust the blade tilt and height to ensure it is aligned correctly.
Miter Gauge Calibration: The miter gauge is used to make crosscuts and angles on a table saw. If the miter gauge is not properly calibrated, it can result in inaccurate cuts. Check that the miter gauge is square to the blade and adjust as necessary.
Table Flatness: A flat table surface is essential for accurate cuts. If the table is not flat, it can cause the workpiece to tilt during the cut, resulting in angled cuts. Use a straightedge or level to check the flatness of the table and make any necessary adjustments.
By addressing these setup issues, you can ensure that your table saw cuts square and accurately. Regular maintenance and adjustments are important to maintain the performance of your table saw and ensure accurate cuts over time.
Low-Quality Blade
If your table saw is not cutting square, one possible reason could be a low-quality blade. A dull or poorly-made blade can cause your cuts to be inaccurate and not square. When the blade is not sharp enough, it can tear through the wood instead of making clean cuts, leading to a lack of precision.
It is important to invest in a high-quality blade for your table saw. Look for blades with carbide tips and made from high-quality steel. These blades are more durable and will provide cleaner cuts, ensuring that your table saw cuts square.
Regular maintenance is also important to keep your blade in good shape. Make sure to clean it regularly and inspect it for any damage or signs of wear. If you notice any issues, replace the blade immediately to avoid any further problems with accuracy.
