how a Circular Saw Cut a 2×4? Step by Step Guide

The first thing you need to do is make sure your blade is right for the job. The 24-tooth, 5-inch blade is the one that works best for cutting 2x4s. You can’t always find that kind of blade, so you have to be creative with what you have.

The 24-tooth blade is the one that works best for cutting 2x4s. A 20-tooth blade or bigger will work, but you may have to remove a lot of material and repeat passes in order for it to cut all the way through.

20-Tooth Blade

If you do have a 20-tooth blade, use it but be aware that you’ll probably need to remove a lot of material and repeat passes to get it all cut.

Not knowing what blade you have is the first mistake most people make when they try to cut a 2×4 with a circular saw.

Another mistake is trying to push down on wood as it goes through the blade, which can cause it to jam.

Before you start cutting

  • you need to buy or find a backer material that’s the same size as your piece of wood. A backer will provide the platform that you need to keep your piece steady while cutting it.
  • You can use plywood, OSB board or a piece of MDF as your backer. Just make sure that you have something that’s sturdy enough to support the wood.
  • You’ll also want to clamp down your backer when you’re cutting the 2×4.

Place your backer

  • board on top of the 2×4. Place it flush with one end of the 2×4. Make sure that your clamps hold it securely in place.
  • You don’t need to clamp down your piece, but it will be more stable if you do.

If your blade

  • is higher than the 2×4, then place a couple of wood blocks under it so it’s level with the board.
  • If your blade is below the 2×4, use two pieces of scrap wood to prop up one end so that it doesn’t fall down onto your blade.

Now you’re ready to cut!

Cutting through a 2×4 can be tricky, especially if all you have is a circular saw and no other tools. You can cut through a 2×4 with a circular saw, but it takes some practice.

You’re going to need to be patient and remember that you may have to remove material several times if your blade isn’t big enough or if it’s dull. It’s also worth mentioning again that you should definitely use a backer board to cut through your 2×4.

Step 1

  • Before you start cutting, position the blade so it’s perfectly level with the edge of the wood. Then slowly lower it down onto the wood until it cuts through completely.
  • About halfway into the cut, turn off your saw and lift up on the saw so it slides out of the wood. Then turn your saw back on and finish making the cut through to the other side of the board.
  • If you leave the saw on, it might jam. Also make sure that you’re cutting with proper form, not trying to force or press down on the saw as it makes its way around the 2×4.

Step 2

  • Apply downward pressure to the saw and cut through your board one section at a time.

Step 3

If you’re having trouble with the cuts, then it’s worth investing in a better blade that can make clean cuts without jamming or breaking.

You’ll need to put more effort into cutting with a cheaper blade and achieve the same results, so if you prefer not to do that then it might be worth paying more for a blade that can cut through 2x4s with less effort.

  • While circular saws are limited to cutting straight lines and basic angles, there’s no reason why they can’t get the job done when it comes to your woodworking projects.
  • Circular saws are handy to have around the home, but they don’t work for every woodworking project. They are limited to making straight cuts or simple angles, although you can use them for almost anything if you know how to make your cuts safely and effectively.
  • Cutting a 2×4 with a circular saw isn’t impossible, but it does take some practice and patience. The key is to make sure you have the right blade and backer board in place to get the best results possible.

Step 4

  • You can also try cutting through your 2×4 by making several cross cuts instead of one long cut.
  • That way you won’t need a bigger blade or a sturdier blade, although you’ll need to make careful cuts with a straight edge.

Step 5

  • Finally, if all else fails, consider investing in a better circular saw that can help you cut through 2x4s with ease and less effort.
  • You may end up paying more in the long run, but it will definitely be worth it if you value your time and safety.
