Table saws are a much-cherished tool in the wood crafting world, and nobody can deny that part. But when it’s about making a 45-degree angle cut, even the professionals might blunder.

Now, the question is, how to cut a 45-degree angle with a table saw?

Proper preparation is crucial for this task. The blade must be set to a suitable height, and you should outline appropriately. Using a tool like a miter gauge, you’ll have to adjust the saw to the 45-degree angle mark. Finish the task by placing the wood firmly in that position.

However, simple mismanagement can cost you heavily. So you must follow all safety procedures!

For Protection: Dust Mask, Safety Glasses, and Earplugs

And if you’re ready with all the tools and safety procedures, we can now proceed to the action part.

Go through the following steps to cut one smooth 45-degree angle with your table saw:

1. Get Prepared

This preparation step is essential to get all the other steps right. Here’s what you got to do:

Turning the saw off to prevent any accidents is a good choice. But unplugging it is recommended.

Using any measuring tool, determine the width and length of your wood. And then mark the places based on where you want the angle cut. Double-check the end and start points. Now, join the marks and outline them darkly.

The blade primarily stays at ⅛ inch. But for cutting angles, it’s better to raise it to ¼ inch. You can do so easily using the adjustment crank.

2. Set Your Angle

This step requires you to be vigilant. Be patient and calmly use the tools to set it to the right angle.

Here’s an overview of what you’ll be doing-

Use the drafting triangle if you’re cross-cutting. And for cutting along the edges, go for the taper jig. Keep the space cleared so you can precisely set the angle.

A miter gauge is a semicircular tool that has different angles marked on it. Use it the following way:

Firstly, You need to hold the gauge tightly and place it against the triangle’s flat edge.

Secondly, move the gauge till its handle moves and points to the exact angle.

Then you’ll have to rotate it clockwise, so the handle locks at your 45-degree angle.

Angled cuts that are done on the board edge are known as bevel cuts. For this type of cut, instead of a miter gauge, you’ll be using the taper jig.

Using a sled-style taper jig is suggested.

First, you’ll have to open the jig and press the wood against it. Next, measure the distance between the jig and the endpoints of the cut. You should be able to set your wood piece at a correct angle this way.

3. Cut the Wood

First and foremost, no matter how frequently you use a table saw, never compromise taking protective measures.

Put on all the safety gear. Use good earplugs and dust masks. With that in mind, let’s get into our final set of steps.

Practice setting angles and cutting on some pieces of scrap wood before. Inspect if the cuts are clean enough and make adjustments as needed.

When you’re going for a 45-degree angle, it’s suggested to go for cutting two pieces together. If the pieces fit all well, it means your miter gauge is set precisely.

One notable feature of the table saw is its metallic fence that ensures utmost safety.

Remove the miter saw out of the way and lay the wood between the saw and fence. Keep the saw aligned with your sketched outline. It’s recommended to leave about 6 inches in between the blade and your hand.

If you’re going for a bevel cut, place the board on its end.

You’ve got your wood piece set at your 45-degree angle, and all you have to do now is to cut it safely. Make sure to stand behind the wood and not the saw blade.

Push the board towards the blade and pull it back after cutting. Lastly, check if the angle is all right.

And you’re done!

Conclusion

By following the correct procedures, using a table saw is as easy as a piece of cake. It’s so simple that you can seamlessly describe how to cut a 45-degree angle with a table saw the next time someone asks you about it. There are other amazing applications of table saws too like rip cutting, cross-cutting, dado cutting, etc. Good luck!
