How to Cut a Baseboard Corners – A Woodworking Tool Guide

In most modern homes, your walls and floors will typically meet at a 90-degree angle, and this is a region most of us like to keep out of sight or covered up for a variety of reasons. The solution for most of us is the use of a baseboard, which is a trip of wood that runs along the entirety of this joint. Whether you’re a beginner trying to learn how to cut and install baseboard corners or an experienced contractor, the process of cutting baseboards is more or less universal.

The techniques, tools, and approaches you can employ will not vary regardless of the type of project involved. The basic design is straightforward for most people, but many people face challenges when it comes to cutting out the corners. The difficulty for most people is that for these joints to work well and look their best, the joints must align and lap perfectly. 

There are different approaches you can use to achieve high-quality baseboard corners, and different tools will be required for each one of them. In this post, we’ll explore some of the most effective and accessible ways to cut baseboard corners with the hope that this may also serve as a woodworking tool guide.

Let’s dive right in.

Cutting Baseboard Corners Using Miter Saws

Miter saws are some of the best tools to use while cutting baseboard corners, thanks to their ability to cut out perfect 90-degree angles. This is ideal for this type of job since these are the angles baseboard corners take, allowing the edges to overlap to perfection and result in a pleasing corner.

They come with crosscut blades with multiple teeth and have adjustable angle settings, making it possible to cut boards at any angle you desire. Here’s how to work with a miter saw:

Mark and Measure the Direction of Your Cut

Take a tape measure and pencil and measure our wall so that you obtain the precise positions you want to place on your baseboard. Make a mark on the outer and inner limits of the intended corner, keeping in mind that the outside edge will be slightly longer than the wall length.

Adjust the Angle of Your Saw

Your saw angle will differ slightly depending on the position of your board, so make your miter angle the appropriate size. Adjust the boards using measurements taken with your bevel. 

Cut the Baseboard Corner

Clamp the board down in the desired position, place the blades at the set marks, and begin cutting. Only cut once the saw has powered fully. Take a hand sander and clean the cut area to make it smooth afterward.

Using a Table Saw to Cut Baseboard Corners

Because miter saws can be difficult to get a hold of if you’re not a woodworking professional, table saws are a great option for getting the job done. Here’s how to get it done:

Measure and Cut Your Board Pieces

Due to the nature of table saws, you’ll first need to cut them down into manageable pieces. Measure out the appropriate sizes and run them along the table for the saw to handle.

Mark the Cut Lines

Take your pieces and carefully measure the angle you wish to cut along (45 degrees). Keep in mind that the outer edges of these boards should be slightly longer than the inner limits.

Cut the Board

Take the prepared boards and run them along the table saw’s path. To achieve the smoothest line possible, let the blade do its job without adding too much pressure of your own to it. Lightly guiding the wood along the path should be more than enough effort on your part.

Using a Circular Saw to Cut Baseboard Corners

Another choice at your disposal when figuring out how to cut baseboard corners is to use a circular saw. These are saws that can be found in most people’s toolsheds, but many people might not consider them their first choice when it comes to projects such as this. It’s possible to use a circular saw when you don’t have access to more precise options such as miter saws, even though the outcome might be slightly rougher along the edges (a hand sander will take care of this). 

Thanks to how circular saws are designed, you can operate them while holding them in your hands and manipulate them to create angles as precise as miter saws. Here’s how to work with a circular saw:

Cut and Measure the Length of Your Boards

Take your tape measure and use it to determine the length of the wall to be baseboards, taking note that you’ll need some extra length on the outer edges of your pieces. Use the circular saw to cut the boards down to the desired size.

Measure the Mark and Intended Angle

Once you have boards of the desired size, make marks at 45-degree angles on adjoining pieces so that they will make a clean 90-degree corner when placed together. 

Make Your Cut Along the Line and Angle

Thanks to the fact that you can operate a circular saw while holding it conveniently in your hands, it will be possible to narrow down your angles and create precise cuts and angles. Be sure to hold the saw steady along the lines you marked out and let the saw warm up to full speed before making contact with the wood.
