  • You will need to make sure that you have a miter saw set up and ready to go
  • Next, you will need to take your baseboard and mark out where you want to make your cuts
  • Once you have your lines marked, you will need to set up your miter saw so that the blade is at the correct angle
  • Now, all you need to do is line up your baseboard with the blade and make your cuts!

So, in the next few paragraphs, we will tell you how to cut baseboard inside-outside corners with a miter saw. Also, to understand this equipment, you will get a guide by the end of the article.

But before that, let’s see what miter saw is all about.

What Is Miter Saw? How to Use it?

What Is Miter Saw? How to Use it?

To understand the process of cutting baseboard inside-outside corners, first, we have to know the machine.

It is a handy and versatile tool, ideal not only for professionals but for all DIY lovers.  Its main function is to cut materials such as wood, metal, and plastic. However, it is currently a basic tool in carpentry, plumbing, and masonry.

The miter saw belongs to the family of circular saws but has special characteristics that differentiate it. The main characteristic of these saws is their precision since the cuts will not depend on our pulse.

The cuts with this type of saw are perfect, thanks to a rotating disk. The disk allows you to work both on the lower and upper parts of the miter saw. Therefore they are usually chosen to carry out the finest jobs.

With the right blade, miter saws can cut a wide variety of materials thanks to their great power. We can say then that the specialty of miter saws are precise cuts of great accuracy.

How to Make Miter Cuts?

The miter cut is a way of calling a cut made at a 45 ° angle. You can follow these tips to make neat and safe miter cuts:

  •         Position the workpiece and clamp it with the collet chuck.
  •         Attach the miter angle to the saw. Miter saws with lasers will project the cutting line onto the workpiece.
  •         Insert the saw slowly and make the cut.
  •         Use all the safety implements.

Before starting, let’s understand the options for a miter saw

As with any tool, there are accessories and options designed to facilitate use:

  •         A laser guide to visualize the line of the cut;
  •         A suction system to remove dust with an attached vacuum cleaner ;
  •         Sergeants to fix the table to a bench;
  •         Stops and presses to hold and lock the wooden pieces on the table;
  •         Extensions to keep the wooden pieces stable;
  •         A transport cart to facilitate movement;
  •         Progressive start-up to avoid shaking;
  •         A speed regulator to adapt to the material;
  •         A slot cutting function to copy those made by a milling machine;
  •         Fine adjustment of angled and slanted cuts.

To cut inside or outside corners, you usually have to cut each piece’s end at 45 degrees. If you are cutting your pieces while standing on the miter, saw, set the angle of the saw to 45 degrees. If the pieces are cut flat, give the blade a 45-degree tilt. If you are working with a miter box, make sure it has slots that have a 45-degree tilt.

Also, we know the angles of the walls should be 90 degrees (two angles of 45 degrees). However, it often happens that this angle differs from this measurement. To get the exact angle of your inside or outside corner, use a false square and protractor. Once the measurement is taken, divide it in half, and you will get the exact angle of your cut.


Do not underestimate the dangers of the electric miter saw. If you need to cut short lengths, use C-clamps to hold the piece. Do not try to bring your hand or fingers near the blade.

You cut the angle opposite to the one you wanted! Who hasn’t already made this mistake?

To remember:

The shorter side of the corner is always on the side of the plinth patterns for inside corners. And this is vice versa for outside corners. You can also keep the scraps from your cuts. They will help you find the right angle for the next molding.

Sometimes it is easier to take exact measurements using a reference point on the tape measure rather than using the hook.

  • Protector for the disc, thus preventing the entry of unwanted objects when cutting a piece of material.
  • Fixing clamp which allows fixing the slats or material to be cut and give it greater stability.
  • Regulating butterflies; adjust the upper work table’s size to achieve the depth of cut you want.
  • Cutting guide; you avoid measuring and marking each cut that you are going to make.
  • Upper lateral guide to be able to mark the measurements to be carried out on the upper work table.
  • Size and power will depend on the work you are going to do and the frequency of the use you plan to give it. From this, choose a miter saw that suits your needs.
  • Connector with a vacuum cleaner, although it does not influence the quality of the cut if it allows working on cleaner surfaces.

If you’re using a power drill, start by drilling a hole in the center of where you want to make your cut. Then, attach the hole saw attachment to the drill and start cutting around the perimeter of the hole. As you get close to finishing your cut, slow down so that you don’t overshoot your mark.

Baseboard Inside Corner 45-Degree

Assuming you would like a blog post discussing how to properly install baseboard in an inside corner that is 45 degrees: When installing baseboard in an inside corner that is 45 degrees, it is important to use a coping saw.

First, you will need to measure the angle of the corner and mark it on the baseboard.

How Do You Get the Outside Corners of Baseboards?

There are a few ways to get clean, sharp outside corners on your baseboards. The first and most important step is to measure and mark your cut lines accurately. A small mistake at the beginning can cause big problems later on.

Once your lines are marked, you have a few options for cutting the boards. You can use a mitre saw, which will give you the cleanest and most precise cuts. If you don’t have access to a mitre saw, you can use a handsaw or even a power drill with a spade bit attachment.

Just be careful not to overcut the corner – it’s better to err on the side of caution and make several shallow passes rather than one deep cut. After the boards are cut, it’s time to install them. Start at the outside corner and work your way in towards the wall.

Use finishing nails or screws to secure the baseboards in place. Be sure to predrill holes for the nails or screws so that you don’t split the wood. Finish up by caulking any gaps between the baseboard and the wall, then paint or stain as desired.
