What Is A Miter Gauge On A Table Saw? | Complete Guide

Do you know what a miter gauge on a table saw is and how it can help you? A miter gauge is an important tool for making accurate crosscuts on a table saw. It slides in the groove on the rip fence and allows you to make angled cuts by setting the angle of the blade.

If you want to know more than in this article, I will outline everything you need to know about miter gauge.

What Is A Miter Gauge On A Table Saw

A miter gauge on a table is a tool that is used to accurately cut any angle that is not possible with a regular table saw or a miter saw.

The miter gauge is bolted securely to the table of a table saw so that a workpiece can be pushed through it at an angle, to make a smooth and accurate cut (known as miter cut).

It is used in conjunction with a miter slot that’s the groove that runs across the table of a table saw. 

Different Miter Gauges

Miter gauges come in different sizes and shapes depending on what type of cut you’re making. They are usually made out of wood, plastic, or metal. There are two types of miter gauges:

  • Fixed-angle miter gauges
  • Variable-angle miter gauged

Fixed-angle miter gauging is done using a fixed angle. Variable-angle miter gaugers use a variable angle. Both types of miter gauges are used to make cuts. When making a cut, there are three angles involved:

  • Cut length
  • Cutting depth
  • Angle of cut

Cutting depth refers to how deep the blade goes into the material. The angle of cut refers to the angle at which the blade makes contact with the material. Miter gauging helps determine the cutting depth and angle of cut.

Types of Miter Gauge

The Miter gauge is used by carpenters and woodworkers to precisely control the angle at which a saw blade is held for cutting miter joints and other types of miters. There are two main types of miter gauges:

Sliding Miter Gauge:

A sliding miter gauge slides along the edge of the material you’re cutting. This type of miter gauge is usually used for cutting large pieces of lumber. It is used for measuring angles up to 90 degrees.

Fixed Miter Gauge:

A fixed miter gauge stays stationary while you cut. This type of mitered gauge is usually used for smaller items such as picture frames. It is used to measure angles greater than 90 degrees. If you’re using a fixed miter gauge, hold it firmly against the material and then move the material away from the gauge.

Both types of miter gauged use a blade to cut the corner. The blade is attached to a lever that moves up and down. When the lever is pulled back, the blade cuts into the material. When using either type of miter gauge, make sure the blade is sharp. Dull blades can cause damage to the material you’re cutting, which could lead to costly repairs.

To use a miter gauge, hold the material against the blade and pull the lever back until the blade hits the corner. Then push the material away from the blade. Once you’ve finished cutting, slide the blade back into its slot.

Miter gauging is essential for cutting wood, metal, plastic, and glass. If you don’t use a miter gauge, you could make angled cuts that aren’t straight. Using a miter gauge ensures that you make straight cuts every time.

Steps To Use a Table Saw Miter Gauge:

  1. Make sure the table saw blade is properly aligned with the fence.

  2. Place the board against the fence.

  3. Adjust the height of the table saw miter gauge.

  4. Set the desired angle of the cut. Then press down firmly on the miter gauge.

  5. Cut the board.

  6. Remove the board from the table saw.

  7. Repeat steps 1 through 6 until all the pieces are cut.

  8. After cutting, remove the miter gauge and clean up the area where you made the cut.

Tips on Using a Miter Gauge:

Here are some tips about using a miter gauge:

  • Use a miter gauge to ensure that your cuts are straight and level.
  • Make sure that your saw blade is set correctly.
  • Hold the miter gauge firmly against the piece of wood you are cutting.
  • Always hold the miter gauge securely while making your cuts.
  • When cutting multiple pieces of wood, place the first piece on top of the second piece. This will prevent the bottom piece from moving.
  • Cut each piece separately.
  • Make sure there is no space between the two pieces of wood.
  • Never leave a miter gauge unattended.
  • Store the miter gauge away from heat and moisture.
  • Be careful when removing the miter gauge from the wood.
  • Do not use a miter gauge if the wood is wet.
  • Avoid using a miter gauge if you are unsure about its safety.
  • Always read the instructions included with the miter gauge.


Q: How do you read a Mitre gauge?

A: Place the blade of the miter gauge against the edge of the material. Hold the gauge firmly in place. Measure the angle using the scale marked on the gauge.

Q: Can I make 45-degree cuts without a miter gauge?

A: No, you cannot make a 45-degree cut without a miter gauge.

Q: What is the difference between a miter gauge and a miter slot?

A: A miter gauge is used for making 90, 45, or 30-degree cuts. A miter slot is used for making 45-degree.

Q: How do you use a miter scale?

A: Miter scales are used to measure the angle of the cut. They are attached to the table and move up and down along with the table. This allows the user to see exactly where the blade is cutting. If you are using a miter saw, then you will probably need a miter scale.

Q: Do you need a miter gauge to cut a 45-degree angle?

A: Yes, you need a miter gauge to use along with a miter slot to cut a 45-degree angle, called a miter cut.

Q: How do you measure the angle of a miter cut on a table saw?

A: To measure the angle of a miter cut, use the edge of the blade. Measure the distance from the tip of the blade to the point where the blade meets the fence. This measurement is called the “blade height.”
Next, measure the distance from the tip to the bottom of the blade. This measurement is called “blade runout.” Blade runout is usually less than 1/16th of an inch. Blade runout is the difference between the top and bottom of the blade.
To calculate the actual angle of the miter cut, subtract the blade runout from the blade height. For example, if the blade height is 3 inches and the blade runout is.25 inches, then the actual angle would be 2.75 degrees.
