The Best Circular Saw Buyers Guide

Nothing in your inventory of power tools works as hard as your circular saw.  This material-chewing beast is the equivalent of the machine gunner in an infantry platoon; laying waste to those heavy-duty general purpose cutting tasks.  There are a few saws on the market that log as many on the job hours as your circular saw.  This saw is the perfect tool for cutting straight or beveled cuts in anything from .25-inch plywood, to 2 x 6 oak planks.

Circular saws are used by nearly every person in the construction industry; from carpenters and tile layers, to roofing contractors and brick layers.  In this guide, we will discuss how a circular saw works, what advantages it offers over other tools, and review the top seven circular saws currently available on the market.

How a Circular Saw Works

A circular saws works just as its name implies.  A round blade spins in a counterclockwise direction as it cuts through material.  Some manufacturers will vary their designs to some extent but overall, most circular saws look and function in a similar manner.  Their thick blades make these saws ideal for cutting dense material.

A base plate on the bottom of the saw rests on the material that you are cutting and the counterclockwise motion of the blade helps the user to keep the saw securely on the work surface.  Many are available with other options such as laser guides and dust blowers.  The dust blowers remove sawdust from the work piece so the user can see their cutting lines at all times.

The most common design for circular saws is called a “sidewinder” design.  In this design, the blade is attached directly to the side of the saws’ motor which supplies the cutting power.  The other design is called a “worm drive”.  With a worm drive, the motor is positioned at a right angle to the blade.  Gears are used to increase the torque that is delivered to the blade so they can cut through tougher material than sidewinder models.  Worm drive circular saws are usually the quieter of the two.

Different Types of Circular Saw Blades

Blades for a circular saw are available in different configurations.  Some blades are made cutting through wood or fibrous materials while others are designed to cut through stone or even metal.  The common sizes usually range from 5.5- inches to 7.25-inches.  One of the main variations that you will find with circular saw blades are the teeth:

  • Flat-Top – Blades with flat-top teeth are used on both hard and soft woods.
  • Alternate Top Bevel – Each tooth alternates between a left bevel and a right bevel. Provides a smoother cut in veneered and natural woods.
  • Combination – Just as their name implies, good for crosscutting and ripping.
  • Triple Chip Grind – Great for cutting plastics, MDF, and laminates, the TCG alternates between a flat tooth and trapeze tooth. Also good for metal cutting.
  • High Alternate Top Bevel – Used for cutting materials that are surfaced with melamine. Melamine is a covering that is predisposed to to chipping.

Advantages to Using a Circular Saw

Unlike many of the other saws you have in your shop, a circular saw cannot cut curved patterns or intricate shapes.  It can however chew through some of the toughest materials commonly used and even cut bevels.  Even though there are saws you may have that can cut finely detailed designs, none of them will chew through the materials you are working with like a circular saw.

Considerations Before Buying

As you start shopping for your circular saw, there are a few things you need to consider as you look.

Design – As we have already mentioned, circular saws come in two main designs, sidewinder and worm.  Your budget and needs will be the determining factor on which to choose.

Size – The size of the saw you get will depend upon what you are planning on using it for.  The most common size, 5.5-inches to 7.25-inches, will be enough for most tasks however.

Blade Type – The best bet here is to buy one of each type of blade.  However, if you only use one particular type of material, you can limit excess spending by only getting the blade you need.  Just ensure the blade you pick will fit your saw.

Price – As with anything you plan on buying, price is a factor that comes into play.  Circular saws range in price from $50 to $400.  More costly models usually are easier to use and are equipped with features that make using them more rewarding.
