Try Square
A fixed 90-degree tool for checking and laying out right angles on wood.
What is it?
The try square combines a steel blade and a stock set at exactly 90 degrees. Woodworkers use it to check square edges and faces and to lay out precise right-angle lines.
What is it used for?
- Checking right angles on stock
- Laying out square cuts and joints
- Verifying machine setups
How to choose
Choose blade length by the work (6 or 12 inch common). A cast or rosewood stock with a graduation-stamped blade is a precision staple.
Anatomy
Understanding the parts of a try square helps you use, maintain, and buy it with confidence.
- Body: the main working portion of the tool
- Working end: the part that contacts the material
- Handle: the part you grip for control and leverage
Materials & construction
Quality try squares are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.
Safety & maintenance
- Inspect the tool before use and replace any that are worn or damaged
- Use the right tool for the job and apply controlled force
- Store tools clean and dry to prevent corrosion
- Wear appropriate eye protection for the work
