How To Cut Miters On a Table Saw? – Complete Guide

Today, I’ll teach you how to use mitre splines to make table saw mitre joints stronger and easier to construct. For a long time, I’ve used mitre joints in my projects, and I’m going to show you how to make them fool-proof.

How To Cut Miters On a Table Saw

The first thing you should do is properly set up your saw. You’ll need enough space between each blade so they don’t get snagged when you cut through your workpiece. Check out our video tutorial on How To Choose A Table Saw if you’re not sure if your saw will work for your project.

If your saw has a fence, make sure it’s in the right place. The fence is designed to keep your material straight as it passes through the saw. It’s critical to make sure the fence is parallel to the blade’s edge (or perpendicular to the direction you are moving). This ensures that the material passes through the saw at the proper angle. Place a square against the front face of the fence to evaluate whether or not it is level. Make sure the square’s two faces are flush with the fence. Then, from the backside of the fence, move the piece of material into the path of the blade and measure. The fence is level and ready to go if the measurements are even.

You can still cut mitre joints without a fence if you designate where you want the material to stop moving. Place a scrap board against the fence to indicate where the material should stop. Cut off any surplus material by sliding the item against the fence.

Setting Up Your Workpieces

It’s time to cut some mitres now that the saw is ready! To begin, select two pieces of stock to serve as the cube’s sides. These parts must be able to extend at least 1/8″ past the saw blade edges. Reduce the size of these parts.
Next, cut another piece of wood to act as the cube’s top. This component must again be large enough to extend at least 1″ but no more than 2″ beyond the ends of the blades.
It’s now time to put the cube’s sides together. Clamp one end of each piece of stock to the saw to begin. Continue to feed the stock through the saw until it comes to a halt. Trim any overhanging material with a sharp utility knife.
Should be repeated for the opposite end of the stock. When you’re done,

Carpenters Square Method

A miter is a tool for cutting 45-degree angles in the ends of boards (or other materials). It may be used for a variety of tasks, but it’s most typically employed to trim or shape wood and plastic objects like moldings and picture frames. Cuts with these sorts of angles can also be made with miter saws. Miters come in a variety of shapes and sizes, but they always have one thing in common: the angle they create. The key distinction is how much material must be removed from the board’s edge before the final cut can be done.
The “inside corner” miter saw and the “outside corner” miter saw are the two fundamental miter saw styles. A 45-degree cut is made along the inner edge of the board with an inside corner miter saw, and a 45-degree cut is made along the outer edge of the board with an outside corner miter saw. Some miter saws come with their own accessories, such as a template to assist you exactly aligning the board. You may need to use a second jig to keep the board in place at other times.
Simply follow these procedures to make a 45-degree miter joint:
Make the incision at a depth of 0.25 inches.
Align the fence with the blade by adjusting it.
Adjust the blade’s height to the appropriate level.
Lower the blade by turning the handle clockwise.
Rotate the workpiece to the right by 90 degrees.
To finish the cut, lower the blade.
Cut the second mitre junction by repeating steps 4–6.
Cut the remaining mitre joints by repeating steps 1–7.
Using a sharp utility knife, trim any overhanging material.
Using 220-grit sandpaper, smooth the surfaces.
Finish with the finish of your choosing.
Use drywall screws to secure the frame to the wall.
Use nails or thumbtacks to hang photographs or artwork.

A mitre saw is a wood-cutting power instrument. It’s similar to a circular saw, but it has movable blades that can be placed at various angles and changed in a variety of ways depending on the project. The horizontal, vertical, half-lap, and dovetail mitres are the most prevalent.
The first two kinds are straightforward: A horizontal mitre saw cuts wood across the grain horizontally, whereas a vertical mitre saw cuts wood vertically. You may also acquire one that cuts in both directions at the same time (known as a “tabletop” cutter).

Miter Saw Safety Tips

There are a few things to bear in mind when operating a miter saw to safeguard your safety. Even if you’re just working on a tiny section of the project, you should always wear eye protection. Never leave the saw unattended, and always make sure the blade is entirely off the ground before lowering it while changing the blade.

Digital Angle Cube Method

This approach enables you to easily measure and mark the precise angle required for each joint. A digital angle cube, which is just a level with an LCD display, is used in this manner. Place the angle cube on the tabletop of your miter saw to utilize this approach. Make sure the blade is set high enough so that the angle cube’s bottom edge is flat with the table saw’s base plate.
After that, line up the board’s edges with the slots on the angle cube. Adjust the angle until the top edge of the board is parallel to the LCD display’s midline. With a pencil, mark the cut’s position. Lower the blade onto the board and carefully slide it back and forth along its length. Continue to move the blade until you reach the required depth.
When it comes to measuring and recording the precise angle, there are a variety of options. However, throughout the years, these three strategies have shown to be the most effective for me.


How do I use my crosscut sled?

Set the blade height to zero first. Then, to the width of your material, adjust the fence. The material should next be slid into the sled. Finally, press the handle forward to secure the sled.

What is the difference between a jig and a sled?

Jigs are usually mounted on the bottom of a table saw blade. A sled is a piece of equipment that attaches to the table saw directly. Jigs are generally more stable than sleds since they don’t rely on the stability of the table saw. Sleds, on the other hand, are more convenient to travel and store because they are not tied to anything.

How do I attach a sled to my table saw?

First, secure one end of the sled to the table saw. Then slip the sled beneath the blade and tighten the screw on the table saw’s opposite side. After you’ve attached the sled, double-check the blade height.

Is it safe to use a hand saw while operating a miter saw?

Yes! Using a hand saw to make a mitre cut is totally acceptable. Remember to switch off the power first. Also, check sure the region around the blade is free of debris. Simply swap to a different blade if you need to cut various pieces of wood.

Which Miter Cutting Method Is The Best?

The sliding compound mitre technique is the most common cutting method among DIY enthusiasts. This technique is ideal for smaller items such as picture frames and cabinet doors. It also gives you a lot of control over the final product.
However, it does not offer the same level of flexibility as the other two approaches. As a result, it might not be the best option for bigger jobs like kitchen cabinets.
The digital angle cube approach could be exactly up your alley if you want something with greater versatility.


A mitre saw is an excellent tool to have in any home workshop. They can help you save time and money by making rapid cuts for jobs that require trimming or finishing.
