What is a Combination Square Set?

The combination square set (also simply called a “combination set”) is a measuring tool which is designed primarily for measuring angles and lengths.

It is used by people working in a number of different trades, including woodworkers and engineers.

“Combination squares” can be purchased without the centre or protractor head, coming simply with the “standard” square head. You may find that carpenters only need to use the square head, whilst the centre and protractor head is more often used by engineers.

However, they are, in essence, the same tools, and centre and protractor heads may still fit on the rules of combination squares bought without them, especially if made by the same manufacturer.

The combination square was one of the inventions of Laroy S. Starrett and was first created in 1878.
