Pinpointing the Most Suitable Miter Saw Blade Size for You

Now that you realize that the blade size matters, you’ll need to learn more about the main three miter saw sizes, as well as the most frequent woodworking tasks that lead to the choice of the necessary type of equipment.

Crown it all with the most reasonable price tag in mind, and you’re on your way to sticking with the most effective tool on the DIY scene.

Exploring the Prevalent Miter Saw Sizes

Similar to most woodworking machines, miter saws are produced in a treasure trove of variations. To be more specific, the blades on these tools come in multiple sizes. On the one hand, it allows you to stay with the exact size you need.

On the other hand, if you’re a beginner woodworker, a choice this extensive may stand in your way of sticking with the ideal miter saw blade size for you.

In a nutshell, there are 3 main blade sizes. Out of the three, one is probably worth laying your hands on, unless you’re planning to use the tool for professional purposes. In the latter situation, i.e., if you’re a savvy carpenter, you already know what we’ll talk about below.

Before we proceed, what every miter saw ‘hunter’ should bear in mind is that blade size is not the only criterion to focus on. Blade type, cutting capacity, power, durability are also vital when it comes to the equipment’s performance.

So, what exactly does miter saw size implies? Does it have anything to do with the height or width of the tool? Not exactly.

It’s the blade that marks the size of the miter saw. In this respect, the 7.5-inch, 10-inch, and 12-inch blade sizes are most frequently applied. The blade size determines the stuff you can work with, its thickness, as well as the machine’s working speed and configuration.

In the next section, we’ll cover more details on choosing a miter saw based on the type of project you’ll utilize it for.

How Big of a Miter Saw Do I Need for My Projects?

If you’re asking this question, you’ll easily get the idea of how to use a power miter saw — and are already on your way to finding the right answer.

Because you already know that the most suitable blade size for you is closely connected to the projects you typically work on. Below, we’ve listed all the details in this respect:

  1. If you’re planning to cut crown molding, then a good 10” is right up your street. If in your case crown molding work involves cuts up to about nine inches, then a durable 12-incher for maximum cutting capacity would be the best choice. A solid 10” will cope with this uneasy task, too. But if that’s your regular work routine and if the idea of making inaccurate cuts seems unappealing to you, then do stick with a high-quality 12” beast.
  2. If you’re planning to cut laminate flooring, the tool choice depends on the circumstances. For tinier cuts, a 10” blade will do. Don’t hesitate and grab a 12” tool for larger cuts. This will aid you in maintaining accuracy, while saving your precious time (in case you’re pressed for it). There’s another essential parameter to keep laser-like focus on here. It’s the type of material you deal with. In case the stuff is average, go for a ten-incher. If the material you need to cut through is tough, a sliding 12” is a must-have.
  3. If you want to cut medium-sized non-industrial baseboards, a top-notch 10” miter saw will be enough. It will excel in cutting 6-in. baseboards with acceptable accuracy. If you already own a 12-incher, feel free to use this miter saw for baseboards. To work with wide baseboards, you’re going to need to purchase a sliding miter saw. Alternatively, a reliable table saw is also a spot-on option.

10 or 12 Inch Miter Saw: Outlining the Nuances

There are cases when substituting a ten-incher for a twelve-incher is a worthless idea. The thing is, larger blades are often incapable of functioning properly in small rooms.

Furthermore, these machines are robust, meaning they can be ‘too much’ for certain not-too-thick types of materials. In other words, if you need a small miter saw for trim work, you can go with a ten-incher without a shadow of a doubt.

At the end of the day, my recommendation is to buy a 10” miter saw instead of a twelve-incher, especially if you’re a DIYer on the hunt for your ‘first baby’ saw.

A 10-inch blade miter saw is a can-do-it-all tool that will help you cope with most jobs once you get the gist of its features. It’s fairly easy to master and exactly what you need for your home woodworking ventures.

In addition to all this, chances are, by the time you start a project requiring a 12-inch miter saw, you’ll already have figured out the best way to use your good old 10-inch miter saw for it. That’s very reasonable and economical, so think about it before buying the first attractive tool you run into.

A Few Words on Blade Interchangeability

Bear in mind that with regard to blade interchangeability, the possibilities are rather limited. Simply put, you can change an old miter saw blade for a new one with the same parameters.

But there’s absolutely no way of using a 12-incher on a 10” machine. That’s the biggest factor that makes the ‘what to choose’ question so difficult for most people who are shopping for this kind of equipment.

Do Take Pricing Into Account

When shopping for the perfect-size machine for your needs, don’t forget about such a vital criterion as pricing. The cost of tools varies significantly from one item to the other, so making sure that the price tag resonates with your budget requirements is something you should definitely take care of.

Remember that with the right amount of practice and effort, you can utilize a smaller blade on the jobs of a larger one. It may take a bit more time in the beginning, but generally speaking, the operation is more than feasible. And it’s cost-effective, unless you need some exceptionally heavy-duty machines for industrial use.
