“table saws may not cut straight due to misaligned blade, dull blade, or improper blade installation.” Table saws are fundamental tools for woodworkers.

They offer precision cuts, saving time and providing even cuts. However, table saws may sometimes fail to cut straight, leading to frustration and uneven cuts. The problem often arises from misaligned blades, improper blade installation, warped blades, or dull blades.

Identifying the problem and addressing it ensures the table saw cuts straight and produces quality cuts. This guide provides insight into the reasons why table saws may not cut straight and how to troubleshoot the issue.

Blunt Blade Or Dull Teeth

A table saw that doesn’t cut straight can be frustrating to work with. One common reason for this issue is a blunt blade or dull teeth. If left unresolved, this can drastically impact the saw’s performance. To identify and solve this issue, check the blade and teeth for dullness, and replace or sharpen them as needed.

Additionally, it’s important to maintain the saw properly to prevent future occurrences, which includes regular cleaning and lubrication. By taking good care of your saw and addressing issues as they arise, you can ensure that it continues to operate smoothly and provide accurate, straight cuts every time.

Worn Out Arbor Bearings

Arbor bearings play a critical role in the performance of a table saw. If they become worn out, the saw may not cut straight. Signs that arbor bearings need to be replaced include excessive vibration, unusual noises, and loose arbor.

Replacing worn out bearings is a relatively straightforward process that involves removing the blade and arbor assembly, pressing off the old bearings, and pressing on the new ones. With regular maintenance and timely replacement of components, it’s possible to keep a table saw cutting straight and true for years to come.

Insufficient Power Supply

Insufficient power supply can greatly affect the performance of a table saw. When there isn’t enough power, the saw blade’s rotation will slow down, leading to a range of cutting issues. To check for power supply problems, start by examining the power cord and outlet.

Necessary actions include ensuring the saw is plugged into a dedicated circuit, using a thick extension cord, and using the appropriate blade for the job. It is important to ensure the saw is receiving adequate power to prevent further cutting issues.


After dealing with an ill-functioning table saw, you now have a better understanding of the possible reasons why your machine fails to cut straight. Whether it’s due to the type or quality of blade and fence, improper calibration, or internal mechanical issues, it’s essential to ensure that your table saw is in good working condition to ensure optimal and safe performance.
