Apart from superior accuracy, another huge benefit is that you can use combination squares with just about any material. Be it for metal fabricating, woodworking, etc.

More often than not, combination squares are outfitted with an interchangeable head. If not, then you have to purchase one separately. What the interchangeable heads do is measure custom angles, common angles, and also identify the precise center of any round workpiece.

Different Types of Combination Squares

The structure, in general, doesn’t change much. It’s just that the size is either small or big. And you have to take this crucial factor into consideration if you want the tool to be useful and accurate for your particular projects.

Larger squares are made for large-scale projects. So it goes without saying that you can’t use these for minor applications. So it’s always a better idea to purchase both big and small combination squares to have access to versatility.

Best Combination Squares - Key Features

1. Size

No doubt about the fact that size matters in this case. What size of combination square you get determines how to use the tool. And this is based on what type of projects you undertake. On that note, it’s always a wise decision to buy multiple sizes.

4. Impact Resistance

Accidentally dropping a combination square is something that sometimes cannot be avoided. In that case, it’s in the best interest of your investment to make sure your tools are impact-resistant. The bubble, in particular, should be immune to mishandling as it’s the most likely to shatter easily.
