Best Cordless Circular Saw Guide

When you’re looking for the best cordless circular saw for the money, you need to know what features are available. Only then can you decide which features meet your needs the best, so you’ll know which one is for you.

Important Circular Saw Fundamentals

Circular Saw Designs

  • Sidewinder saws are the traditional circular saws that are the most commonly used. The motor on a sidewinder saw is found on the same axis as the blade, and the blade is driven by the shaft that runs straight to the motor. In comparison to worm drive saws, the sidewinders are more compact and lightweight, and they can be used for most circular saw projects.
  • Inline Saws, or worm drive saws, place their motors next to the saw blade at a right angle. Gears are used by the motor to increase the torque that is conveyed to the blade. Worm drive saws are usually quieter and longer, and they’re a good saw for heavy-duty use.

Circular Saw Power Sources

  • Cordless circular saws are super convenient on the worksite, especially when having an extension cord can cause safety issues. They’re usually smaller than a corded circular saw, so they work well in small spaces. These are great for cutting wood due to their battery power limits, although they can cut tougher materials, they take up a lot of power and kills the battery fast. Normal cordless saw sizes range from 5-3/8 to 6-1/2 inches.
  • Corded circular saws are better for tougher jobs as they don’t have batteries that’ll die quickly. The normal size for a corded saw is 7-1/4 inches, and they normally require an appropriate extension cord.

Circular Saw Features

The function of a circular saw is to make fast and straight crosscuts across a board or along the length of aboard. Circular saws can also be used for bevel cuts. Basic features include the following…

  • Blade Guard – When the saw is not in use, the blade guard covers the blade for safety, and it retracts to reveal the blade when you are ready to use it.
  • Foot Plate – This is also called a shoe, and it keeps the saw steady up against the wood.
  • Bevel Adjustment – This lets your footplate move relative to the blade, and it is used to make bevel cuts.
  • Bevel Capacity – This tells you the maximum bevel cut that your saw can make.
  • Bevel Stops – These are preset that let you make fast adjustments for bevel cuts.
  • Size – Diameters are used to classify circular saw sizes with 5-1/2 to 7-1/4 as the most common sizes.
  • Blade Capacity – This is the capacity or maximum depth of cut that a saw can make. Basically, the larger your blade is, the deeper the cut you can make. Also, saws that have a smaller hold capacity are more lightweight and are easier to control.
  • Electric Brakes – The brakes on a saw will reverse the electrical flow in the saw motor when you push the trigger release. When you reverse the electrical flow, you quickly stop the blade’s momentum in as much as two seconds. This feature stops the blade a lot faster than a saw that does not have this feature.
  • Spindle or Shaft Lock – This makes blade changes a lot easier by immobilizing the blade and shaft.
  • Laser Guides – Guides help increase your cutting accuracy by aiming a light beam onto your work area.

Circular Saw Blades

Different blades are used for different projects. Always make sure the blade you’re purchasing is compatible with your saw when you’re buying one. Here are a few tips on buying blades.

High-speed steel blades

These blades are stronger than steel blades and also stays sharper longer.

Carbide-tipped blades

These have carbide tips that are attached to their teeth. They stay sharper longer than high-speed or steel, but they are more expensive.

Tile-cutting blades

These blades are specially designed tile-cutting blades used for cutting ceramic tile, and some of the better quality tile-cutting blades come with diamond-tipped blades.

Masonry blades

These are used on abrasive material like a brick, concrete, cinder block, and other masonry materials.
