Pros
  • Easily haul it around – the weight of 24.2 pounds
  • Able to fit in most tight spots – measured by 18-1/8
Cons
  • The brake slows the blade rapidly

According to our testing, the Metabo HPT Compound 10" Miter Saw is the best option you can buy.

It is 10” sized, which goes everywhere more easily than the 12" dual bevel sliding or 100lb radial arm. It’s also compact enough to fit in narrow quarters and lightweight enough to be used by one hand.

Yet, there’s plenty of power in this guy for 2”x6” or 2x4” studs as well as accuracy for window molding, base, or crown.

The cut with the stock blade is really smooth. Regardless, its price point can’t be lower.

How To Choose The Most Accurate Miter Saw?

Size

When choosing a miter saw, there will be several sizes for you to choose from. Normally, a sliding compound miter saw at the size of 8.5 inches can handle 85% of the jobs you need to do.

Specifically, if you often work with base and crown cuts, you should get a saw of 10 or 12 inches in size. But if you mostly make flat cuts on the base, you should opt for an 8.5-inch miter saw as it’s more portable. All in all, when choosing a size, follow these rules:

  • The 12-inch type is for cutting deeper materials like 1x12 and you have space for a larger saw, especially a stand. This size is suitable for cutting vertical crown tall as well.
  • The 10-inch type is for those who want both portability and capacity.
  • A miter saw smaller than 10 inches is suitable for those who prefer portability and need to cut smaller crown, base, and door trim.

Types

One of the first and foremost things you need to decide on when shopping for a miter saw is the type. Regarding this matter, you face 5 options.

  • Sliding miter saw: this type features rails that allow the saw blade to slide back and forth across the wood, offering much deeper cuts than miter saws without rails. This type is suitable for deeper materials such as 1x12 and 2x12 lumber. But these saws are not compact.
  • Compound miter saw: consisting of a bevel and miter, this type can miter and make bevel cuts, suitable for crown molding.
  • A basic miter saw: this type can make cross cuts as well as miters, but not bevel cuts. These saws are lightweight and cheap but have limited cutting depth and width.
  • Compound sliding miter saw: this type has rails for larger crosscut capacity and a left bevel for compound cuts. It’s suitable for deeper material such as 1x12 and 2x12 lumber but not portable.
  • Dual compound sliding miter saw: this type comes with sliding rails, a miter table, as well as beveling that goes left and right. Using these miter saws, you don’t have to flip the material around for the opposite compound cut. All in all, they are suitable for a base flat and bevel-cut crown, but they cost more.

Cord or Cordless

While this seems not prominent, you will also need to decide if you want a corded or cordless tool as it’s related to portability.

If you feel that a cordless miter saw can help you save a great deal of time and energy, there are many battery-power models available that offer the same power as corded models.

Which Brands Make The Most Accurate Miter Saw?

Makita

Founded in 1915, this company has built a reputation for its research and development capability. Its products are incredibly durable and quality.

DEWALT

With nearly a century of experience in the power tool business, this is the leading brand to buy from. It focuses on design and innovation to help you increase productivity.

FAQs

Which is better 10 or 12 miter saw?

This depends on your preference and the material you will cut. The 12-inch size offers more cutting power for deeper material but the 10-inch size is more portable and has more blades available.

Are sliding miter saws accurate?

Yes, sliding miter saws allow for precise cuts.

What size miter saw is best?

The best size of a miter saw depends on the use of each person. But it seems that the 10-inch size is the best of both worlds by offering both cutting capacity and portability.

Will a 10-inch miter saw cut a 4x4?

Yes, it will. In fact, the 10-inch miter saw can make perfect 4x4 cuts.

Do I really need a dual bevel miter saw?

This depends on your needs. If you are a professional who wants extreme convenience when cutting wood by not having to flip the material around, this is the perfect tool for you. But other types like a compound sliding miter saw can make such cuts well.

Conclusion

We hope that this post has provided all the information you’re looking for to find the most accurate miter saw. There are a number of factors to take into account, but remember that regardless of the size and budget, you must always pay attention to the accuracy of these tools
