A Combination Square Set with Protractor (also known as a Combination Set) is a multi-purpose precision instrument used in woodworking, metalworking, and engineering. It consists of a graduated steel rule and three interchangeable heads: a square head, a protractor head, and a center head, all designed to slide along and lock onto the rule.
