Can a 10 inch Miter Saw Cut a 4×4? – Ultimate Cutting Guide

Written by | Updated On July 14, 2020

Last week, we were having a conversation with DIY amateur woodworkers and consulting their frequent problems. A common and valid query was raised there and many times before too – Can a 10 inch miter saw cut a 4×4? There’s a lot of debate and confusion over this issue!

Yet we can solve it by examining different perspectives like cutting capacity, types of miter saws, how many cuts you are willing to, and more. Let’s find out whether it would be an ordeal for your 10″ best miter saw or not! 

What 10-inch miter saw does?

Before we get into the details, we should take a quick look at what 10-inch miter saw does.

The 10-inch blade can do angle crosscuts that are up to 5 inches wide, generally seldom more than 4 inches. For beginners miter saw, a 10″ miter saw is your best bet. We can cut through the material more quickly and have smoother edges. They’re less expensive to purchase in the first place and don’t use as much power to operate, saving your money on your utility bill.

If we compare the blade with 12″ miter saw, the 10″ miter is faster. The 10″ blade will have a higher RPM rate than 12-inch blade on an equal-powered motor. And higher RPMs mean a finer finishing. The 10″ blades are easier to handle, and the cuts they make are less aggressive. 

We can do more jobs with our 10″ miter saw. If we are cutting a 4 to 5 inches crown molding or smaller laminate flooring or baseboards, we can try our 10″ miter saw.

Can we use a 10-inch miter saw to cut 4×4?

If we want to answer with one word, we can say – Yes. We can. But we have so many other things to consider! 

We always misunderstood that the size of blades only matters the cutting capacity. But the design of the saw also determines the cutting capacity of the power tools. 

Generally, a sliding 10″ milter saw has a higher cutting capacity, versatility, and torque than a stationary one. The sliding saw can tilt back and forth so you can have a range of motions. And this feature increases the cutting capacity too.

Again, when you want excellent crosscuts, and confused about buying a circular saw vs miter saw, you should buy a miter saw. Miter saws can cut through wood, plastic, and some metals depending on the kind of blade that we are using. 

Remember, the blade angle can be changed quite drastically in relation to the fence. You can have either very precise angles adjusting 1 degree at a time or preset common cuts like 15, 30 or 45 degrees.

The kerf of the blade also influences the cutting capacity. Thinner kerf can render smoother cuts. 

After all of these considerations, if you want to be frugal in this pandemic situation and want to cut some 4×4 studs by your 10″ miter saw, you need to follow our cutting steps with some preparations. Since cutting 4×4 dimensions is around the highest range for 10″ blade, we have to be cautious about the blades. We should cut the 4×4 with 10″ inch miter saw occasionally. 

If you have a 10″ inch miter saw, we recommend you not to cut any piece which is bigger than 4×4.

Now there’s a question that may arise in your mind – Will a 12-inch blade do a better job?

Generally, if you consider buying a 12″ miter saw for some larger jobs or power or cutting capacity, the 12-inch miter saw is the creme de la creme. It can do all types of crosscuts on wider and thicker pieces of lumber. But if all you need is a miter saw to cut 4x4s, I would definitely recommend you to save your bank and stay with a regular, 10-inch miter saw.

How to cut a 4×4?

We need to follow some precautions cutting 4×4 with miter saw. Let’s go through the steps carefully – 

Step 1: Marking the stock

Grab your pencil and draw a line or mark on the 4×4. This process ensures appropriate measurements and some degree of accuracy. 

* Mark the piece on all the sides. 

Step 2: Preparing the saw

The next step is to prepare the saw. Remember to make good stability on your workbench as the motor will be pushed to its limit.

Now, calibrate the blade’s angle on at a 90-degree angle so that it will fall straight down. 

* Always recheck the angle when you are working with a square to have an accurate cut.

Step 3: Positioning the 4×4 

Place the stock on the workbench and put the marked area under the blade. 

* You can fix the 4×4 to your workbench if you don’t have repeated cuts, and thus you can avoid kickback too. 

Step 4: Cutting the 4×4 

Now comes the tricky part. Again, you can get used to it after a couple of times. You will need finesse, time, and patience to do this step. 

  • Firstly, start your saw when the head is in the resting position. 
  • Then, bring it down slowly towards the mark and again push down firmly to 4×4 for more stability. Now, once you have done with one side, bring the blade back up and stop the saw. 
  • Flip the other side of the stock to the blade and then again continue the process. 

Following these steps can deliver you a smooth, clean edge with your miter saw. 

Don’t try to cut the piece with one stroke. It will end up in rough cuts and also damage the saw. And wear a pair of earmuffs and protective goggles.
