How Wide Are Miter Slots?

Miter slots are the long, narrow channels cut into the top and bottom of a woodworking table saw’s table. These slots are used to guide the miter gauge or crosscut sled for precise, repeatable cuts.

The width of a miter slot can vary depending on the manufacturer, but they are typically 3/4″ wide or less.

While the width of a miter slot may not seem like an important measurement, it can actually have a big impact on the accuracy of your cuts. A wider miter slot will provide more support for the miter gauge or sled, which can help to prevent the gauge from wobbling during a cut.

This can lead to cleaner, more accurate cuts.

However, wider miter slots can also make it more difficult to keep your workpiece aligned with the blade. This is because there is less room for error when positioning the workpiece in the wider slot.

For this reason, some woodworkers prefer narrower miter slots for greater control over their cuts.

Ultimately, the width of miter slot you use is a matter of personal preference. Experiment with different widths to see what works best for you and your woodworking projects.
