7 miter saw blades to change the way you cut.

You could be forgiven for thinking all miter saw blades are the same. But they are not.

In your daily DIY or professional life, you deal with many types of materials, and they all have different considerations that should be kept in mind when cutting them.

We talk you through the best miter saw blades in each category so that you get the results you deserve.


When Should I Replace My Miter Saw Blade?

Unfortunately, there is no exact answer. Miter saw blades don’t have indicator lights that tell you when you should change them. So it comes down to experience and blade manufacturer recommendations.

The first thing is to read the operating manual. This will indicate the frequency of blade changes. Next, consider what you are sawing. If you are chopping through softwood, the blade will last longer. If you are cutting sheet metal or hardwood, it has a greater impact on the condition of the blade.

The third consideration is the quality of the saw blade. What material is it? Carbon steel varieties dull faster than those made from cobalt steel or carbide-tipped tungsten.

The fourth factor is how well the saw cuts. If you’ve noticed that tasks take longer to complete, it is a sign that your saw blade is dull.

And finally, it depends how many times you use the saw. If you use it every day, expect to change the blade every two weeks to a month. However, if you are using your miter saw infrequently, that same blade could last you for years.

How Do I Choose a Miter Saw Blade?

Buying the right miter saw blade is crucial for the best outcomes in your projects. So, here is a handy guide to help you.

Blade Material

Miter saw blades come in several materials, designed to cater to different projects.

Carbon Steel

Carbon steel is the cheapest type of miter saw. It caters to soft materials and plastics. Carbon steel blades dull quickly due to their soft teeth, so don’t expect them to stand up to the rigors of frequent use.

High-Speed Steel (HSS)

High-speed steel blades are more robust when compared to carbon steel blades. They retain their cutting edge better and perform at higher temperatures, meaning the blades are less likely to dull.

Typically, these blades can withstand heat up to 600 degrees centigrade and score between 62 and 66 on the Rockwell Hardness Scale. Because they run at higher speeds, HSS blades will cut through MDF and hardwood with ease.

Cobalt Steel Blades

Cobalt steel blades are an alloy, containing 8 percent cobalt. This makes them robust and able to withstand even more punishment than the HSS blades. Like the HSS varieties, cobalt steel blades also withstand high temperatures, making them hard-wearing and resistant to dulling.

Carbide-Tipped Blades

These blades are more expensive because they are incredibly robust. They typically score 65 to 80 on the Rockwell Hardness Scale, making them among the hardest wearing blades you can buy. They cut through sheet metal, aluminum and even steel.

Blade Size

The material you are cutting dictates the size of the blade. For sheet material, you will want a thin edge for finer lines. Also, unless you are sawing multiple sheets at one time, the depth of the blade won’t matter much.

However, if you are cutting thick lumber, you will want the maximum depth blade you can get.

The Bore

Check the bore size on your machine by consulting the owner’s manual. The bore size is crucial if you want the blade to fit your device.

The Diameter

If the diameter is too large, this could affect the blade guard and become a safety issue. Again, the manual will address this, along with the width of a suitable blade. The wider the blade, the wider the cut.

Remember

All the measurements are etched on the surface of the blade.

Number of Teeth

What material you cut is crucial to choosing the correct blade, and the number of teeth is a guiding factor. It is called the tooth per inch, or TPI for short.

Type of BladeTPITotal Number of TeethSuitable For
Coarse3 to 840 to 60Lumber, hardwood, softwood, MDF
Medium8 to 1860 to 80Lumber, hardwood, softwood, MDF, plyboard, sheet metals
Fine18 to 3280 to 120Plyboard, frames, sheet material, non-ferrous metal

Quick Note

A blade with 60 to 80 teeth makes the best general-purpose blade and should be suitable for most tasks.

Kerf

Kerf refers to the width of the cut, which relates directly to the width of the blade. The kerf is often thinner than the center of the blade as it tapers towards the edge. A full kerf has an edge measuring 0.125 inches, while a thin kerf is 0.094 inches.

Full kerfs are more durable and better suited to cutting through tougher material. However, you will need a bigger motor if you are using a full kerf. A thin kerf suits finer detail work and creates less wastage. The downside is that these blades are prone to greater damage as they are less durable.

Remember

A full kerf blade will increase the strain on your miter saw motor. Check that you have the power to run a full kerf blade.

Type of Saw

Miter saws come in all shapes and sizes. You can get single and double bevel miter saws, as well as sliding varieties. The blade sizes vary from 8-inch, 10-inch and 12-inch, so the blades need to match the saw size.


The Best Miter Saw Blades of 2020

With so many miter saw blades to choose from, we reviewed dozens of varieties to help you arrive at the right choice for your miter saw and project.

1. Makita A-9368110-Inch Miter Saw Blade

Best Miter Saw Blade for Hardwood

Makita A-93681 10-Inch 80 Tooth Micro Polished Mitersaw Blade
Check Price

This Makita is a 10-inch blade, so it is slightly smaller than some on the list. It means it will decrease the depth that you can cut, but if you intend on sawing through thinner material, this won’t be a problem.

The 80 carbide teeth are honed using 600 grit to provide a mirror finish. The ultra-thin kerf means you get a smoother cut with less drag on the motor, and less material wastage. Plus, the teeth are hook teeth with a 5-degree angle, with an alternative top and face design for precision cutting.

The other advantage of hook teeth is that they scoop the debris and sawdust away. This reduces the chances of the blade gumming, which creates kickback. It also means you get a better sightline when you are cutting.

The only downside to this blade is the cost. It is a Bosch, so we know it isn’t going to be cheap, but other manufacturers offer packs of blades for similar prices. That said, this saw blade slices through hardwood, softwood and plyboard with ease and is a quality product.

PROS:
  • Carbide-tipped blades.
  • Hook teeth.
  • Ultra-thin kerf.
  • Fine crosscutting.
CONS:
  • Expensive.

How to Clean and Maintain Your Miter Saw Blade

If you want to get the maximum use from your miter saw blade, you will need to clean it from time to time to maintain it.

  1. Place the blade in water: Once you have removed the blade from the saw, take some all-purpose cleaner and dilute it in warm water in a washing-up bowl. Place the blade in the water and immerse it. Leave it to soak for a few minutes to allow the detergent to do its work.
  2. Scrub: Remove the blade carefully and scrub away any stubborn areas with a toothbrush. Immerse it back in the water, taking care to grip the blade by the center hole and give it a shake in the water to wash away any final bits of debris.
  3. Dry: Lift the blade from the water and dry it thoroughly with a cloth.

You could also make sure that after each use, you take a brush and wipe the surface of the saw blade. This sweeps away any loose debris that may become compacted and cause damage. And one of the best ways to maintain your saw and blade is to use oil and lubricant on the moving parts that require it to keep them working smoothly.

Top Tip

Some people use citrus products to keep their blades shiny and clean.

How to Sharpen a Miter Saw Blade by Hand

You can use a power tool to do this, which would be much quicker. However, sharpening a saw blade only takes about twenty minutes at the most, even when you are using a file.

1. Unplug the Saw

Before you do anything, make sure the saw is unplugged and switched off. Never attempt to remove the blade with the machine plugged in.

2. Loosen the Wrench

Many miter saws have a fastening wrench. Simply loosen this to remove the blade.

3. Remove the Blade

Carefully remove the blade. Take a marker pen and mark the blade at the point where you intend to start sharpening. Now clamp the blade in a vice, making sure the teeth are free.

4. Grab a File

Grab a triangular file. The teeth are set at a specific angle, so make sure you don’t deviate from this. Place the file on the start point where you marked on the blade with the pen.

5. Zig-Zag the File

Run the file to match the same angle of the teeth and work in a zig-zag fashion, working backward and forwards four times. Now skip the next tooth and repeat the process for every other tooth.

6. Flip the Blade

Once all the way round, flip the blade and start working in the same manner on the teeth that face the other way, working towards your marker.

7. Clean Up the Blade

Remove the blade and give it a clean with some soapy water. Make sure the blade is completely dry before inserting it back into the saw.


The Cutting Edge

Miter saws are versatile tools, but when you factor in the right blade for the task, you improve your results enormously. The design of the teeth, the angle and the way the teeth are sharpened all make a difference to the outcome of your project.

Think about the material you are working with and how it behaves when you are sawing. Is it brittle, does it splinter? Choosing the right blade is crucial if you want your project to look like it was completed by a professional.
