Into To The Top Rated Combination Squares For Construction or Home Use
Invented by Laroy Starrett in 1883, a combination square is a tool that few understand how many uses it really has. This tool is used in woodworking, metal work, and stone masonry in multiple ways. At its simplest, a combination square consists of a ruler (or ruled blade) and a head or handle attached to it. The head may be a standard or square head, but a combination square could also have a protractor head and/or a center head.
The standard or square handle or head is the mostly common one and is used to lay out or check right angles and 45-degree angles. The handle basically contains two parts, the shoulder and an anvil. The shoulder is at a 45-degree angle from the ruler or ruled blade in order to mark or find 45-degree angles. The anvil forms a 90-degree angle with the ruler and can be used for determining or creating right or 90-degree angles. The handle also contains an adjustable knob so that it can be moved along the ruler, depending on the size of the job. Usually the head contains a vial that acts as a level to determine if surfaces are level. Combination squares often usually contain a scriber, which is a scratching tool to mark a surface at a certain location, even on tough surfaces. Very hand when you don’t have a pencil!
Let’s Take a Look at 10 of The Best Combination Squares on The Market With Reviews
The combination square is most commonly used to find a 45-degree angle or a 90-degree angle and create a perfectly perpendicular surface. However, the combination square has a whole host of uses other than the measuring of 45-degree and 90 degree angles as mentioned above. It can also measure the center of round surfaces or determine flatness of a surface. If the model features an attached protractor, it is useful for measuring angles or setting angles. It can also be used as a depth gauge and most models contain a rudimentary level for determining if flat surfaces are even. When turned vertical, this vial can be used as a plumb. With all of these features in a lightweight tool, why would any professional or do-it-yourself hobbyist not have one of these valuable devices!
You need to consider the kind of job to do when choosing a combination square. Make sure you buy one to handle the scale of job that you are doing. In other words, the bigger the space or job, the bigger the combination square you’ll need. Another factor is durability. Consider what materials were used to make the blade and the handle or head. Also check for extra features or accessories that might be handy.
