Why Should You Use a Circular Saw to Cut 2×4?

As stated earlier, there are dozens of methods to cut a 2×4 lumber, but there is hardly any that comes close to using a circular saw.

The circular saw blade comes in different variations, each packed with dozens of sharp-edged teeth. The circular saw also has a motor capable of generating a tremendous amount of power. Other tools like the jigsaw can cut the 2×4 lumber, but not as fast and easy as the circular blade.

To put it in a much simpler perspective, the correct circular saw blade will cut through your 2×4 lumber like a hot knife through butter. With the circular saw, you can successfully cut through dozens of 2×4 lumber in minutes.

Tools needed to cut a 2×4 lumber

Using a circular saw takes some level of getting used to. You need to practice and have a bit of experience to use the tool, so get yourself acquainted with how to use the tool properly if you are a beginner. To use a circular saw to effectively cut a 2×4 lumber, you need the following:

  • Safety gear: for this task, you need gloves and eye protection (goggles).
  • A circular saw: It’s important to pick out a saw that feels handy, light and generates enough power to execute the task. Check here our review about circular saws.
  • A circular saw blade: the “combination blade” is suited for cutting a 2×4 lumber.
  • A power source and outlet if you are using an electric circular saw: most circular saws are electrically powered.
  • A clamp: this is to hold the lumber in place while cutting. If you don’t have a clamp, make sure to get something that can hold the 2×4 lumber firmly while sawing.
  • A marker and a ruler: you can get a pencil. A marker and a ruler will allow you to make straight markings on the point of the 2×4 lumber you want to cut.
  • A measuring tape: this is used to measure the length and breadth of the area to make accurate markings and cuts on the 2×4 lumber. A tape rule or measuring tape will suffice.

Tips and Pointers on cutting a 2×4 lumber with a circular saw

  • Use the correct blade. Circular saw blades come in different designs, several teeth and each has a specific purpose. To cut a 2×4 lumber, use a combination blade. The combination blade is a kind of all-purpose blade for woodwork. Using the wrong blade will give you a very uneven and messy result
  • Always start slow. Don’t be too hasty to cut through if you are inexperienced.
  • Secure the wood firmly while cutting: if your lumber is not firmly locked in, your blade can get stuck leading to a kickback. A kickback is when the wood thrusts backward at a very high speed.
  • If you discover that your cut is not aligning with the marked line, stop and start over to ensure a clean and accurate cut.
