What Is a Combination Square?
A combination square is an essential multi-functional precision tool for measuring and layout in woodworking, metalworking, and machining. Built with a durable stainless steel ruler and clear etched graduations, it delivers accurate measurements every time.
Square head: Measures right angles and depths with precision
Protractor head (select units): Marks and measures angles up to 180° — ideal for bevel cuts and layout tasks
Center finder (select units): Locates the center of round stock or pipe — perfect for drilling and turning applications
Adjustable mechanism: Smooth sliding blade for easy alignment across a range of tasks
Whether you’re a professional machinist, pattern maker, woodworker, or serious hobbyist, a quality combination square is one of the most versatile tools in your kit.
