Circular Saw Types And Features
Any circular saw you choose is going to come equipped with several basic features. When shopping for saws, you will see they are classified by their blade diameter. Most commonly, blades range from 5.5 inches to 7.25 inches.
The blade guard is a crucial safety feature on any circular saw. When the saw is not being used, it covers and protects the blade (and your fingers) from damage. It can be easily retracted in order to expose the blade when it is being used.
The foot plate is a base piece intended to keep the saw steady by pressing against the wood or other material while sawing. Circular saws have a depth adjustment setting that allows you to to move the foot plate so you can accommodate different thicknesses in your materials. The bevel adjustment allows the foot plate to tilt so you can make bevel cuts at the desired angle.
All circular saws are capable of making three basic cuts on wood or other materials. The first is a crosscut which simply means the saw cuts straight across a board. Rip cuts move along the length of the board. Bevel cuts refer to angled cuts that require a bit more creativity and adjustment of your saw settings.
Finally, you are going to run into two basic types of circular saws while you are shopping. The most common type is the sidewinder (or inline) circular saw. These saws have a more traditional appearance with the motor sitting on the same axis as the blade. A shaft connects the blade and motor in order to run it with precision. This type of saw can perform most tasks required from a circular saw, and they are often lightweight and easy to maneuver.
The worm drive saw is a bit heavier and more cumbersome because its motor sits at a right angle to the saw blade. Instead of a shaft, it uses gears to move the blade adding more power than a sidewinder saw. This makes it great for those heavy duty jobs.
Don't Run In Circles: Choose Right The First Time
The type of circular saw you buy is going to boil down to how you plan to use it. Aside from the basic choice between sidewinder and worm saws, you will run into options you might not have considered.
First, decide if you want a cordless or corded saw. This decision will be largely based on where you plan to use your saw and what type of job lay ahead. An obvious advantage to the cordless saw is its convenience. If you are working in a tight space, the cordless circular saw might be your best bet. If you plan to use a cordless saw for your next project, try to stick to cutting wood. Some can cut other materials, but the extra power necessary can drain the battery quickly and take up more time than necessary.
Corded circular saws are more powerful because they don’t have to rely on a limited battery. They can chew through steel, masonry, and are excellent choices for those heavy duty wood cutting jobs. The biggest drawback to a corded circular saw is that you might have to purchase a compatible extension cord.
Second, don’t buy a circular saw without first checking the blade capacity. The blade capacity is the maximum depth that the blade can cut. This feature is indicated by the size of the blade. The bigger the blade, the deeper it will cut. If you have thick pieces that need to be cut, you will want to go with the larger blade. However, if precision and control are your priority, smaller blades are a better choice.
Third, electric brakes are a favorite safety feature of many circular saw users. When the user releases the trigger, the electric brakes reverse the momentum and can stop the blade in nearly two seconds. If your circular saw has this feature, it greatly improves safety.
Other important features, depending on your intended use include spindle locks, bevel capacity, bevel stops, and laser guides. All of these features improve the accuracy and quality of your cuts and improve the ease of use of your circular saw. Laser guides are especially helpful because they use a light beam to show the cutting line.
A Brief History of the Circular Saw
There is a lot of debate over who is the inventor of the first circular saw. Differing stories are told with several European countries claiming first rights. For instance, some say that Samuel Miller invented the first circular saw machine, but it is argued that he didn’t invent the blade to go with it. Others say the dutch were the first to use a circular saw in the seventeenth century.
However, in the United States, we hear a completely different story altogether. Tabitha Babbitt was in Harvard, Massachusetts when it was rumored that she saw two men struggling to saw a log with a pit saw. She then took it upon herself to make a tin disk with notches that could be attached to and spun with her spinning wheel. This significantly cut down on sawing time, and the idea was eventually used in saw mills.
Babbitt was unable to obtain a patent due to her religion, but her invention lives on and has been improved upon over the years. York Saw Works was established in 1906 with its most popular product being the circular saw. This invention has been perfected over time and is now available in many different varieties including hand saws and table saws and is still one of the most popular tools in production today.
