An Overview On Circular Saws

Circular saws are one of the most popular power tools out there, and having one is an absolute must for any DIYer or craftsperson. Circular saws come in a number of styles and configurations. One of the first considerations when choosing a circular saw is whether you want a corded or cordless model.

Cordless models are generally smaller and provide the convenience of transporting the saw someplace else, or operating in spaces where extension cords are unavailable or unsafe. However, the batteries on cordless saws drain quickly when cutting tougher or thicker material. Corded saws are generally slightly larger and can provide more cutting power for longer periods of time.

The other major determining factor in circular saws is blade size. Along with corded or cordless designations, most circular saws are referred to by the specs of their cutting edges. The most common blade size is 7  1/4 inches. Blade size determines the cutting depth of the saw, or what thickness of material it’s capable of cutting through in one go. Saw manufacturers will often include straight-down cutting depth in a circular saw’s specifications, and sometimes also 45-degree cutting depth.

Circular saws also vary by type of motor. Sidewinder circular saws are the most common, in which the motor is aligned along the same axis as the blade. These versatile tools are suited to most applications. Worm drive saws have the motor positioned at a right angle to the blade and use gears to increase the torque transferred to the blade. These powerful devices are ideal for heavy-duty jobs, but they are also heavier.

Regardless of the type of saw you choose, you should verify that you know how to use it safely before getting started. A good way to accomplish this is by spending some time with the instruction manual before you do anything else.

Other considerations with circular saws include shoe material, guides and bevel abilities. The shoe is the foot plate that rests on the work surface, and it can be made from a variety of materials, including aluminum, steel and magnesium. When considering shoe materials, it’s important to balance durability and weight. Shoes can also incorporate guides for measuring and aligning cuts.

Finally, a saw’s bevel abilities refer to the angles at which it can cut. If you work on a number of complicated projects that might require more than a few standard angles, you should seek a circular saw with enhanced capabilities.

DWYM Fun Fact

The history of the circular saw is shrouded in some degree of mystery. The first patent filed for it, in 1777, may indicate that circular saw blades were already in common use by that time.

Since then, the circular saw has evolved into a compact, portable and versatile tool. Another type of saw with a circular blade is the table saw, which provides a flat surface and a stationary blade, with the work piece being maneuvered towards the saw.

 

The Circular Saw Buying Guide

  • Consider whether your planned jobs will require angled or beveled cuts. Circular saws with bevel capabilities often have “stops” at specific angles to aid in making accurate bevel cuts.
  • The most common stops are 45 degrees and 22 1/2 degrees.
  • Blade material is a crucial factor in determining what the circular saw can cut and how quickly the blade will dull.
  • Blade types include steel, high-speed steel, carbide-tipped, tile-cutting and masonry blades.
  • Ergonomics are important when comparing circular saws. The various knobs, handles and other surfaces should be suited to the size of your hand and be comfortable to grip and operate.
  • Be sure to buy safety gear like goggles, work gloves and a dust mask when you order your circular saw. You should use these, along with long pants, long sleeves and steel-toed shoes, while you work with power tools.
