How To Choose The Best Speed Square

There are many ways you can end up choosing a speed square, but it’s always critical to do it right, or you won’t have a pleasant experience using the piece. For that, there are several factors to consider:

The most common material is aluminum. We recommend it for people who want a sturdy but still light option. Framers and woodworkers who operate small jobs often get the most of aluminum models.

But if you are someone who needs a larger and sturdier piece, then you’ll want something made of steel. In workshops, a steel square also helps to work as a guide for saws if needed.

You’ll want a speed square that has readable markings that you can see at any moment. For that, we recommend pieces with colored numbers and measurements over any other type of marking.

Some models also have stamped markings, while others have deep carvings as marks, and the rarest of all may come with numbers and lines as protuberances.

The color is also important. If you can go for a black square with yellow or white markings, that will be a much better choice than a metallic or white square with black numbers.

Additional Tools
Some additional tools like protractors and scribe notches are standard features of speed squares. We heavily recommend picking the pieces with the highest number of features so you can get the most out of it.

Some options come with additional levels, while others offer a cutting guide or base that works as a sturdy fence. Anything that adds more practicality to the tool is an excellent option to go for.

How To Use Speed Square Tools For Wood Working Project

Even if you have the best speed square for woodworking, it is essential that you know how to use it. Otherwise, it can be a complete waste of money. Here we teach you how to get the best out of your speed square instead:

Angle Marking
This is one of the most regular uses of a speed square. And it is probably one of the easiest too.

The only step to take is to just adjust the pivot to the board or wood, and then mark the piece by swinging the rafter to one side.

To know which the angle you want to mark is, you’ll have to match the markings of the angles to the edge or a

You should mark following the path from the edge or starting point to the finish point or last angle of the square.
This will help you have a much more accurate angle marking experience.

Measuring Pitches
The pitch is the part of a roof or object that veers down. For example, a speed square pitch would be the one on the side, the angle that goes down.

The work of a speed square to measure pitches helps to make them more accurate. It does this by placing the side of the square on top of an angle with the border that has no base.

Then, you’ll use the flat base or guide part of the square to measure the pitch with a level. You’ll have to make sure the level is flat completely. Otherwise, it will tell you a different pitch measurement according to the marks on the side.

Fencing Saw Cuts
To use the speed square as a fence for saw cuts is even easier than the previous two modes of use. You just need to grab the side of the square that has the flat base or added fence and place it against the guide of the saw.

This way, you can make 45-degree or 90-degree angle cuts depending on your needs. Just make sure the flat base or the fence of the square is directly on the guide of the saw for accurate results.
