As a woodworker, you probably don’t have any other choice than to invest in a good miter saw to make your work easier. In the market today, you have a myriad of miter saws that you can pick from.

However, the 10-inch and 12-inch miter saws, are the two sizes that are common among woodworkers. Both miter saw sizes could actually be useful for various woodworking projects, but you may have to determine the one you want as both offer different uses.

Read on as we examine and take a closer look at the contrasting facts of these two miter saws.


10-inch miter saw

Firstly, let’s look at the qualities that make up a typical 10-inch miter saw.

1. Speed

One of the perks of a 10-inch miter saw is that they spin faster as compared to its 12-inch counterpart. More paces are created with a 10-inch miter saw.

What explains this is the size of the blade – having a smaller radius makes them spin more rapidly and consequently creating a smoother and more accurate cut.

This doesn’t only help you get more work done in little time but also deliver superior quality work.

2. Blades

A sharp blade is an essential feature when it comes to creating a good quality workpiece. A smaller radius blade spins faster through material than a larger one leaving behind the smoothest cuts possible. Basically, the faster the blade, the smoother the cut it creates.

Additionally, it’s no doubt that a 10-inch blade is less likely to wobble, hence delivers straighter and more precise cuts.

Replacing the blade is also easy to do as it is more available, and you don’t have to search hard to get the best fit. And perhaps, you want to cut some budget, sharpening the miter saw blade also doesn’t cost much.

The small surface area of the 10” blade causes more pressure to be exerted on the material comparatively. You probably may have heard somewhere that pressure = 1/surface area.

Hence, when the surface is less, the pressure will increase.

3. Portability and flexibility

One of the good things about a 10-inch miter saw is its size plus versatility.

With this, a 10-inch miter saw will take up less space in your workshop or workspace and provide for a freer surrounding. That also means no need for a special room to operate. This also contributes to the ease of movement of the miter saw from one place to another.

Hence, it is possible to use at various locations like shuttling between job site projects and your workshop without much stress.

4. Price

As expected for any power tool, the more you take it higher, the more the price gets. Of course, a 10-inch miter saw is relatively cheaper in price than its 12-inch counterpart.

12-inch miter saw

1. Power

No doubt, many of the 12-inch miter saws available are more powerful than the 10-inch miter saws. The amperage of the saw tells you the power capacity of the miter saw; all you have to do is check for it to find out.

Many of the 12-inch miter saws come with a 15-amp motor providing you enough power to cut through thicker and larger pieces of materials. However, you may not need a 12-inch miter saw for standard cuts.

2. Blade

Also, one good feature of some 12-inch miter saw is that you can also use a 10-inch miter blade.

The combination of the motor power and the 10-inch miter blade may be a big plus for faster and smoother cuts. The higher revolutions of the blade per minute help the saw to deliver more precise and accurate cuts for finer woodworking.

They also work well for laminates and plywood.

3. Construction

The durability that 12-inch miter saws offer is also something major to talk about.

The use of the powerful motor ensures there is no excess strain on the miter saw as it cuts through hard materials. No strain also means that the cutting blade will stay sharp for a longer period. This makes the miter saw last longer. Although this may shoot up your utility bill a bit, it allows you to make cuts in lesser time and saves you some time to do more.

They have tougher construction to handle more difficult jobs.

4. Price

The 12-inch miter saw typically costs more than a 10-inch miter saw. Also, the replacement of blades may incur more costs.
