Buyer's Guide

Benefits of Using a Power Circular Saw

Here are some of the benefits that you can expect when using a power circular saw:

  • Portability

Most models of power circular saws are designed with portability in mind. As such, they are easy to bring wherever you want to go. This is also beneficial especially if you only have a limited space for working with your tools, as you can easily fit this tool in a small space.

  • Convenience

One of the most obvious benefits offered by a power circular saw compared to a manual one is convenience. While a manual saw may need more hard work and physical labor, a power circular saw will allow you to finish a job faster. As such, this type of saw can save you energy and time compared to a manual hand saw.

  • Precision

A circular saw is designed with precision in mind. For instance, the vertical cut angle may be adjusted from the standard 90 to 45 degrees, or any in-between angle. Even the cutting depth can be pre-adjusted as well. This means that the moment you use the saw, you can already expect the quality of the output.

What Makes a Good Circular Saw?

One thing is for sure. You will find a number of options on power circular saws on the market. Choosing the best one for your needs can be challenging. However, by taking into consideration the following features, you can still end up with a model that is ideal for you.

  • Saw Style

There are different types of circular saws that you might encounter on the market. You can choose from worm drive, sidewinder, small sidewinder, cordless, as well as a trim saws. Each of these types offer their own set of benefits and drawbacks. Choose one that will fit not just your needs, but your preferences as well.

  • Shoe Styles

One thing that you need to realistically anticipate is that there will come a time that you will end up dropping your saw. Choose a circular saw that is equipped with raised reinforcing ribs located on the top, as they will not bend as compared to flat aluminum shoes when hitting the ground. On top of that, a cast metal shoe may add more weight to the circular saw.

  • Adjustment Options

Smooth cornered, bigger lever locks as well as full-round knobs which may be tightened down using the entire hand are often more convenient, because it becomes easier and faster to adjust the cutting depth, as well as bevel settings compared to hard-to-grasp, small wing nuts and levers.

Reviews & Testimonials

One customer mentioned that he purchased this model mainly because it is made by a recognized name in the industry. Aside from that, he admires that this tool can “cut very well”, as it is equipped with great blades that are carbide tipped. The line is easy to follow, thus making every cut precise.

Another customer described it as a “cutting edge saw”. He tried it on different types of wood, particularly cedar, pine and oak. According to the customer, the saw is powerful, terrific, and solid, without unnecessarily being heavy. The calibration marks are also accurate and clear for depth. Since the base plate is made of aluminum, the weight is kept down as well.

Not all customers give positive feedback, however. For instance, one mentioned that the case is big, which means that it can take too much space. Another also wished that this model could have had a blade brake as well as a rip guide. These are fairly minor responses, compared to the positive ones given by most customers.
