What Is A Speed Square Used For?
We first need to know what a speed square is. A speed square is a marking-out tool that is triangular and is mostly used by carpenters to ensure accurate results.

Other features include a fence that is lipped, numbers that are deeply engraved, cutouts, and notches. All these play a good role in ensuring that it delivers excellent output altogether.
Additionally, there are wordings on the speed square that one needs to clearly familiar with. There is the degree that outlines the degrees ranging from 0 to 90. Common is basically used to show the increase that occurs over a 12-inch common rafter that is between inches 1 to 30.

Uses Of A Speed Square
1. Acts as a guide for the saw
If you are using a circular saw to cut across a piece of wood, then you must consider a speed square to garner excellent and accurate results. You can be able to attain precise 45- and 90-degree angle cuts if guided by a speed square.

The speed square is suitable for use as a saw guide because it is thicker as compared to a combination or a framing square. This ensures that the saw does not slide against the speed square hence accuracy. Besides, it makes sure you are safe when working on your lumber.

4. Protracting purposes
Protracting basically involves reading angles and thereafter marking them to be useful for your work later. Because of the degree markings on the edge of the speed square, it becomes easy to protract.
If you need to mark an angle of 60 degrees, ensure to place the pivot point firmly in opposition to the board that you are working on. Finish by drawing a line across the square found on the diagonal edge’s opposite side and then make the cut.
