Quality Craftsmanship: Top 5 Best Combination Square Reviews

A combination square is a great and valuable addition to any woodworking, metal or mason workshop. This tool will help you make accurate and precise square cuts for your projects. Remember that you don’t have to be a pro to construct nicely finished structures. As long as you are a dedicated craftsman, quality, accuracy, and precision should be your driving force.

With that said, let’s look at what makes a combination square, how to identify the best of this tool and also reviews of some of its best models in the market.

What is a Combination Square?

Like we’ve mentioned above, a combination square is a measuring and marking tool. It is majorly used to mark right angles when making square cuts, checking internal and external right angles and marking right angled miters. Of all marking and testing tools, it is the most versatile one; although it can be quite challenging to use if you are not used to.

This tool can also be used in various other applications e.g. it can be used as a depth gauge for mortises.

Combination squares are made of steel, and the structure consists of a ruler and a head (sliding square). Just loosen the bolt to slide the head up and down the ruler. To fix the square head in place, just tighten the bolt again.

Some of this tool are designed with an optional protractor head while other also have a 3rd attachment known as the center head.

In this section, we will discuss the various applications of the combination square and the specialty of each head attachment. Use this as a guide to help you choose the best features and also learn how to use each one of them.

A basic combination square usually has a level in the square head, if you come across one that lacks a level then move on to the next item. Why? Because the level is very useful in woodworking and if you go with a tool that doesn’t have one, then you will miss out on its very significant uses.

Another significant feature is the 45° angle feature, although you will find some squares that have 90° angle feature which isn’t that useful. The scriber is also a mother feature to look out for in a combination square. It is a small rod that is sharpened to a point and is used to cut guidelines in wood projects.

If you want a more professional and versatile tool, then an optional protractor head is a good consideration to make. This one can measure a variety of angles which enable you to create more precise and accurate angles in wood. If you are going for a protractor head, choose one with level.

The other optional piece we mentioned was the center head. This one is used in determining the center of a circular project like the center of a dowel or a plate. Any round project pieces need to be measured on a center head to determine the most central point of the project.

Using the center head is not in any form complicated. You just need to place the circular edge onto the piece and mark a line. Repeat this from the other side of the material you are working on and mark another line. The point where the two lines intersect is the exact center of the woodworking piece.

Other Things to Consider when Looking For an ideal Combination Square

Once you have established your type of application and the correct attachment you want to your project it becomes easier to choose a tool that will enable you to mark and test wood for your projects. Determining the application only is however not enough, you should also consider the size of the tool. Remember that size will go by the space and size of job you are doing. Therefore, buy a big combination square if you will be handling larger projects and a smaller one for small projects. Keep in mind that the bigger the job or space, the bigger the tool needed.

Besides, the price is also crucial to consider. Combination squares are priced differently depending on materials used, size, manufacturers, design and even the features presented in the tool. If you are on a tight budget, then choose from the low-end combination squares; these are not in actuality poor quality, they are just a bit economical with essential features. Otherwise, if you are a machinist or work at a professional level, then make a one-time investment of a high-end square with optional attachments and a wide array of features.

Apart of application size and price, other things to consider should improve the accuracy of the tool, versatility, ease of use (if you can’t handle it before purchase then you won’t be able to after purchase) and durability. You should ensure that the materials used are durable of good quality and so should be any other additional features of the square.
