Every building or home improvement project requires you to possess all the right tools ahead of time. Every professional carpenter owns or has access to a speed square—a tool used to measure and mark precise angles in pieces of wood for guiding saw cuts. Most speed square tools are multipurpose and are very useful when it comes to checking the accuracy of your cut. They also come in various sizes and feature a simple layout for easy use. Here are some we recommend.
What to Look for in Speed Squares
Here’s what you’ll want to know before making a purchase:
- Features: Speed squares usually include a ruler, T-edge, diamond-shaped hole, and lines that mark out varying degrees of angles. Each feature plays a role in how you use and manipulate the tool so that you can make precise and accurate cuts using a saw. You can measure angles by lining up the speed square with the edge of the board and then pivoting the tool until it aligns with a specific angle.
- Ease of Use: Look for clearly marked measurements so that the speed square is actually speedy and straightforward to use.
