Last Updated On May 3, 2023

You may need a piece of 4×4 wood with bevel cuts for your DIY projects or other constructional works. In that case, a circular saw can be a handy tool due to its adaptability and mobility. But how to cut 4×4 with a circular saw?

Generally, cutting a 4×4 bevel cut with a circular is relatively easier than other alternatives. First, ensure that the wood is secured and marked, then adjust the blade and place it over the wood. Now let it cut through the lumber slowly.

Read on to learn the step-by-step process in detail.

How To Cut 4×4 With A Circular Saw?

Here, we’ll break down the process of how to cut a 4×4 bevel with circular saw step by step for your precise understanding.

Step 1: Secure The Cutting Piece

If you want an accurate and precise result of the final cutting piece, then you must secure the beam first for enough grip and support. Clamp your beam into a flat, even, and solid table.

Step 2: Estimate And Mark It

Now you need to measure and mark the piece according to the final piece you want. Measuring the cutting piece twice before starting the process is ideal for ensuring every measurement is right. Using a pencil to mark is preferable so that you can erase the previous mark in case of re-marking.

Step 3: Adjust The Cutting Depth And Line The Blade

Circular saws are versatile but have some limitations in terms of cutting depth. You just can’t grab the tool and cut through a 4×4 beam because it won’t. 

Generally, a traditional circular saw includes a 6-1/2” or 7-1/4” blade which has the highest cutting depth of 2-1/8” and 2-1/2” for 90° cuts. But you need to cut 3-1/2” with the blade for a 4×4 beam. Therefore, you need to ensure that the blade in your saw is capable of cutting all the way through a 4×4.

Now line up your saw’s blade on the cutting piece. Make sure the angle of the blade is accurate, and the blade is square.

Step 4: Cut

After you’ve secured, measured, and marked the wood and the blade is in its place, it’s high time that you cut the beam. Start from the scrap end and cut the piece gradually. 

Suppose you want the final piece to be 6’ long and 4×4, and you’ve measured the wood from the right. In that case, the left side is the ideal side to place the blade. This way, you can cut through the wood perfectly.

Step 5: Turn The Wood And Cut it Again

Now unclamp the beam, flip the wood at 90°, and then secure it again. Cut the wood again following the similar method explained above. Follow the same cutting and flipping method until you get the 4 cuts, and the final piece is separated from the original piece.

Step 6: Finish The Task

The final step is inspecting the final piece. Check whether the measurements are correctly cut and if any area of the 4×4 piece needs sanding for leveling. And if everything is okay, then congress, you did it!
