Do you know why the zero on a table saw is offset?
The answer to this question may surprise you. When the blade of a table saw is at its lowest point, the distance from the blade to the fence is actually greater than when the blade is at its highest point. This means that if you were to measure from the blade to the fence at its lowest point, and then again at its highest point, you would get two different measurements.
Why does this happen? The reason for this offset has to do with physics – specifically, with torque. When the blade of a table saw is at its highest point, it produces more torque than when it’s at its lowest point. This extra torque causes the blade to move away from the fence, which results in an offset between the blade and the fence.

Why is the zero on a table saw offset?
Here are some reasons:
- The fence on a table saw is typically set to the right of the blade. That way, when you rip aboard, the fence will be on the opposite side of the blade and you won’t have to worry about your hands coming too close to the blade. If the zero were in the middle of the blade, it would be very easy to accidentally cut yourself while pushing a board against the fence.
- Another reason is that it’s easier to make accurate cuts when the zero is offset. If the blade was in the middle of the table, your cuts would be off-center because of how the board moves as it slides across the table. By having the zero offset, your cuts will be more accurate since they’re being made in the same spot each time.
- The third reason is that the offset helps to keep the board from binding against the fence. If the zero were in the middle of the blade, there would be a small gap between the board and the fence. This could cause the board to bind against the fence and create dangerous kickbacks. By having the zero offset, there is more room between the blade and fence, which prevents binding and kickback.
- The fourth reason is that it’s easier to see the blade when it’s offset. If the blade was in the middle of the table, it would be difficult to see where the cut is going to be made. By having the zero offset, you can easily see where the blade is and make accurate cuts.
So there are several reasons why the zero is typically offset on a table saw. It makes it safer to use, more accurate, and easier to see. Having it offset also helps to prevent binding and kickback.
Here are some tips for staying safe when using the zero on a table saw offset:
- Always use a push stick or push pad when woodworking with a table saw. This will keep your hands away from the blade.
- Keep your fingers retracted when pushing the wood through the saw.
- Don’t try to free a piece of wood that is stuck in the blade. Wait until the blade has stopped completely before trying to remove the wood.
- Make sure the fence is parallel to the blade and that it is adjusted properly before cutting.
- Be aware of where your hands are at all times when working with a table saw.
Is there a specific time when you would want to use an offset zero?
There is no one-size-fits-all answer to this question. Sometimes, an offset zero can be helpful when you are making miter cuts. However, it is always important to use caution when working with a table saw, regardless of the settings you are using.
Can I use the zero on a table saw to make angled cuts?
Yes, you can use the zero on a table saw to make angled cuts. However, it is important to be aware of the potential dangers of doing so and to take all necessary precautions when using this type of saw.
Is there a way to permanently fix the zero so that it doesn’t move?
There is no way to permanently fix the zero so that it doesn’t move. It is important to be aware of this and to adjust the setting as necessary when switching between different saw blades or types of wood.
So there you have it. The zero on a table saw is offset for two reasons- to make it easier to line up the fence with the blade and to keep the distance between the blade and fence consistent as the blade moves up and down.
We hope this explanation was helpful and cleared up any confusion about this common woodworking term. Have you ever used a table saw? If so, did you know why the zero was offset? Let us know in the comments below!
