As someone who works in construction and doing some personal woodworking on the side, there's a profound need for a reliable tool with more than mediocre performance. You will find me working on a variety of things, from cutting tube fittings to doing various cuts on maple or any type of hard wood. Doing construction and woodworking has given me countless opportunities to enjoy what I do. Making something out of nothing is already a joy on its own.

During my construction and woodworking jobs, I often found myself using the circular saw more and more. I use it to cut hardwood that I use to make pieces of furniture, and house parts like windows, doors, etc. However, most of the blades of the circular saws that I've been using tend to wobble during prolonged use. There was also a time when the circular saw wasn't able to output the necessary power to make an efficient cut on the wood.

How I wished that the Bosch CS5 120-Volt 7-1/4-Inch Circular Saw was on hand back then. I am not saying that the previous circular saws that I used were of low quality. They are fantastic when they worked properly, but there is something more with the Bosch CS 5 that makes it both elegant and rugged at the same time.

Who Is It For?

The Bosch CS5 120-Volt 7-1/4-Inch Circular Saw is for construction and woodworking nuts who are looking for an all-around circular saw that could do the job whenever, wherever. While lighter than its counterpart from other brands, it packs enough power that could make hardwood look like butter.

When I was looking for a circular saw, I was looking for more than something that would make efficient wooden cuts. I was looking for something that would need minimal maintenance, robust, powerful and light enough to bring anywhere I go. This particular saw is by far, the one that meets all those categories. It is extremely lightweight, powerful, and has a pretty solid build to it.

With a circular saw like this, I never have to worry whether it will be able to make an efficient cut on the hardwood that I will be putting it against. It is indeed a great portable power saw solution. In addition, it also has a good price to performance ratio.

Buyer's Guide

Benefits Every Circular Saw Should Have

Compared to other forms of circular saws, a 120-Volt 7-1/4-Inch Circular Saw is unique on its own. Below are some of the benefits that you can expect out of using one:

  • Powerful Motor

One of the biggest advantages of a power circular saw is that it has an extremely powerful motor. The motor is what makes the bulk of the circular saw. Different saws come with different power output, so make sure you choose the right saw with the right power output for your needs.

  • Simple Efficiency

Among the numerous advantages of the circular saw is its efficiency. Its advantage over the reciprocating saw is that it shortens the cutting time of the reciprocating saw in half. Whenever the blade of the circular saw is turning, it is ready to cut. It’ll cut fast since it doesn’t require a return stroke like the reciprocating saw

  • Portability

Most electric circular saws are also portable. They are lightweight and will fit into any normal saw case. You don’t have to worry about lounging around a humongous power tool whenever you move construction site to construction site.

Things to Consider When Buying a Circular Saw

Of course, a circular saw is a great solution whenever you are looking to cut materials in half the time that it normally would take. However, that is not enough. You also have to take into consideration its build quality, functionality, and usability. Below are some recommended tips that you help you avoid the most common mistakes when choosing a circular saw:

  • Philosophy of Use

When selecting a circular saw, the first thing that you have to think about is what will you use it for. Of course you will use it for cutting materials. But what kind of materials will you be cutting most often. You surely don't need a metal saw if majority of the materials that you will be working on is wood. There's a power output difference between the circular saws for wood and the ones for metal. Obviously, you will require more power in cutting metal compared to wood. So before buying, think of how you will use it and what you will use it for.

  • Saw Functionality

Another thing to consider is the functionality of the saw. Is the safety mechanism of the saw appropriate? Is the operating mechanism easy to access? When you cut wood, the shavings and dust will go spewing everywhere. Does the saw offer a dust chute to prevent those shavings and dust from going to your face? These are just some of the questions you need to ask before picking the right circular saw for you.

  • Saw Durability

The most important part of the saw selection process is its durability. Whatever saw you pick, it must be durable enough to withstand the ruggedness of normal use. During selection, try to ask the hardware attendant if there is any possibility that you could do a durability test on the saw. Feel the saw in your hand. Try to drop it from knee height and see if it comes apart right away. Saws need to be tough since they are construction tools after all. See if the blade assembly is stable during operation and will not fall apart during operation.

This can be remedied, though, by purchasing a separate dust chute for the saw. But for the most part, the reviews were excellent.
