Speed Squares Frequently Asked Questions
Which is the most common size for speed square?
There are many sizes of speed squares on the market. It can be hard to pick one that will work best for you. The most popular size is 7 inches, but there are also 6 inch and 12-inch options available. Determine your needs before picking an extent, so you don’t get stuck with an item that doesn’t fit your needs or expectations.
On the other hand, you can use these sizes for different purposes. For example, if you have just started working with wood or another material, a 7-inch square will work best! Choose one appropriate to your needs and expectations to fit nicely into what type of project you will be doing.
What are the primary purposes for your speed square?
The Speed Square is the Swiss army knife of carpenters everywhere. Not only does it include all the functions of a combination square, try square, and framing square – but it also includes basic measurements like length and area in both imperial (inches) or metric (centimeters).
The Speed Square combines a framing square, try square, and combination square in one device. It is used to make basic measurements on dimensional lumber and marking lines when cutting with a saw at 45 or 90-degree angles.
Why is a speed square called a speed square?
It was an invention by Albert Swanson way back in 1925. He would later create the Swanson Tool Co., and the name Speed Square is branded to them, but the name has stuck to describe them.
A Speed Square is called a speed square because it can be used to quickly calculate the most common angles in carpentry (90 and 45 degrees) and use this tool to mark lumber lines when cutting with saws. A framing, try, or combination square is not always convenient enough, so people find these functions useful all packed into one tool.
How thick is a speed square?
Speed squares come in different thicknesses on their various sides. A thicker side is often designed to be a saw guide, making it quite thick and dangerous for some people since you may not expect the edge of such an object to be sharp that could cut your hand. The other sides are typically thinner, so they won’t slice down through whatever material or sheet metal you’re using them with.
