How To Choose A Circular Saw?

Are you in the market for a new circular saw? If so, it can be tricky to determine which one is right for you. There are a lot of different factors to consider, from the size and power of the saw to its features and price. In this blog post, we’ll outline the key things to look for when choosing a circular saw and provide some tips on how to find the best one for your needs. Let’s get started!

Body style 

There are three different styles of circular saws: worm drive, sidewinder, and direct drive. Within each style, there are several sub-styles that differ greatly in their power sources and functionality. Let’s take a closer look at these options.

Size & power 

Large saws (over 10″ diameter) are typically used by contractors and are heavy (10 lbs. or more), but they can tear through any job with ease. Even when cutting thick material like 2x4s, the weight of the saw makes it easy to use so you don’t have to apply pressure while cutting. Lighter-weight models (around 7″ diameter) are easier for smaller hands to handle, so if you’re looking for something your size – especially if you want a light-duty option for home projects – this is what we recommend.

Saw power 

Electric vs. cordless? The corded electric models will be less expensive than their cordless counterparts, but you’ll need an extension cord and an outdoor outlet in order to use them. Cordless saws are free from power cord limitations, but they’re usually more expensive and require a battery. The most powerful of the bunch, worm drive saws can be very heavy, but also pack a punch that you won’t find in other types of circular saws.

Blade size 

The blade itself is measured in inches and there are three standard sizes: 7 ¼”, 8″ & 10″. Each size has its own pros and cons. For example, small blades (7 ¼”) have lower torque so they may stall on thick material or when cutting with the grain, while larger blades (8″+) cut faster but create a smaller kerf (width of cut). So if you want to minimize splintering wood as you cut (such as with face frame cabinets), go for a larger blade – but you’ll need to make more passes.

Blade shape 

Circular saw blades come in either the standard round shape or an alternate bevel style that’s ideal for cutting into walls and other angled areas.

Quality of components 

The best circular saws include cast magnesium components, such as the motor housing and gear case cover, which make them even more durable than usual. Cheaper models typically use stamped steel instead. Other features like dust blowers help keep your line of cut clear, providing better visibility to what you’re cutting and improving safety on the job site.

How to choose the right circular saw for your needs?

How much do you plan to use the saw and how often will impact your purchase. The more you’ll be using it, the more important features like power and durability become. If you’re using it infrequently, a cheaper model may suit you just fine.

Pros of using a circular saw :

  1. Save time 
  2. Less elbow grease needed when using a circular saw because it is easier to use than using other saws.
  3. Can be used for various purposes, projects, and cuts.
  4. Can be used by anyone to cut almost anything with minimal effort or pressure while cutting.

Cons of using a circular saw:

  1. Sawdust can be very dangerous and harmful to your lungs. Make sure you wear a mask when cutting with a circular saw to avoid breathing in any harmful particles.
  2. Very sharp blade. Be extremely careful not to cut yourself while using the circular saw. 
  3. If you are not wearing protective equipment on your hands, use a pair of gloves to protect yourself from any harm that may come.
  4. Can be difficult for first time users. Using a new tool can be hard at first but with practice it will become easier and more comfortable to use the circular saw.

How is a circular saw used?

A circular saw is used by placing the blade on the material you want to cut and then pushing it through. You can use a tape measure or ruler to mark where you need to make the cuts.

Some models of circular saws include a laser guide, which will show where your blade will go if you place it over the measurements from your tape measure or ruler.

The blade should be at a 45 degree angle when you are marking your measurements. The tape measure or ruler will lean against the angled blade while you’re making your mark on the material you want to cut via the saw.

When actually using your circular saw, adjust the depth of cut so that it is just below where you marked. The more you gradually lower the saw, the more accurate and cleaner your cut will be.

Make sure to wear goggles or a face mask while making a cut to avoid any chips from flying into your eyes or on to your face. When cutting through a piece of thick material, you may have to place some pressure on the top part of the material to keep it in place while cutting.

When you are finished with your cut, make sure to turn off your circular saw and let it cool down for a little bit before putting it away or taking it apart. 

What are the important safety precautions when using a circular saw?

  1. Always wear protective gear when operating any type of saw. When using a circular saw, make sure to wear goggles or some type of face mask to protect your eyes and face.
  2. You should also wear heavy duty gloves that will provide hand protection while you are cutting with the circular saw.
  3. Always keep an eye on where the blade is at all times when making a cut with a circular saw.
  4. Another safety precaution you should follow is to never use the circular saw on wet or damp surfaces. The water can cause the blade to slip, which will result in injury if not careful.
  5. Always disconnect your circular saw from power before putting it away for storage. If you are moving the circular saw around a lot, place it in a carrying bag so you can move it around without having to worry about accidentally cutting yourself or others.
