Things to Look for When Buying Miter Saw Blade for Composite Decking

If you are a complete beginner and this is your first time choosing a blade for your composite decking project then this portion will help you. 

I highly recommend reading everything in this section before making your final decision as it will make things a lot easier for you. 

Here are some of the most important things that you need to look for while buying the right miter saw blade for composite decking. 

Blade Diameter

There are two types of blades when it comes to diameter and they are the standard blade (less than 12-inches) and the heavy-duty blade which is more than 12-inch.

The smaller blades will not be able to work well with thicker composite boards that range up to ¾ inch or so in thickness while larger blades can handle such boards.

So, if you are dealing with boards that have a thickness of at least ¾ inch then the standard blades will not be enough for your project and you should go for the heavy duty blade instead. 

The general rule here is to use smaller blades when working on thinner boards while larger ones can handle thicker boards without any issue whatsoever.

Number of teeth 

When working on projects like composite decking you will need to pick a blade carefully. Apart from the cutting depth, you will need to pay attention to the number of teeth a blade has. 

When looking for a blade for composite decking you need to pick a blade that has at least  40 teeth. If you can find a blade with 60 or 80 teeth then that would be even better but it is not really necessary.

The reason why the number of teeth matters so much when working on composite decking materials is that these are usually very round and small in diameter. It means they need more precision to cut smoothly without tearing the material.

Thinner blades will not be able to cut through these materials with the same precision. 

You would need a blade that is less than or equal to 16 teeth for thinner boards, but any thicker board will need at least 40 teeth.

It’s important you use anything over 80 tooth if possible because this allows smoother cuts and better results

Kerf Size 

Another important factor that you need to keep in mind while selecting the blade is the kerf size.  

The kerf size is the width of a blade’s path. 

For composite decking, you will need to use blades with smaller kerfs because these work better for thin materials and produce cleaner cuts without tearing or splintering them apart. 

A bigger kerf can be used if you require more aggressive cutting action but this will usually not be the best option for your miter saw. 

Hook Angle 

Hook Angle is something that most beginners forget to look for. However, it is also one of the most important factors to keep in mind while selecting the right blade for your composite decking. 

 The hook angle is the degree away from the vertical that your cutting edge sits. 

A blade with a greater positive hook angle will cut more aggressively and be able to take on thicker materials better, while a negative hook angle will have less aggressive action and deal well with thin material. 

If you want to use composite decking for outdoor buildings, you will want to use a blade with a negative hook angle.

If you are using the composite decking for indoor purposes or if your saw has an adjustable base plate that can be set at any desired height, then you should go ahead and buy blades that have a positive hook angle. 

These blades cut more aggressively but still manage to do a good job with thin material.

Frequently Asked Questions

Do you need a special saw blade to cut composite decking?

Yes, you will need a blade specifically designed for cutting composite decking. This is because the teeth on this type of blade are set at an angle that allows it to cut through the material with ease. 

They also feature chipping points that prevent the wood from being torn like in regular saw blades. The hook angle of these blades is about 20 degrees.

Can you rip cut composite decking?

No, it is not recommended that you rip cut composite decking. This is because the material has a tendency to chip and tear apart if it’s done in this manner. It is best to use a blade designed for ripping that can handle the material.

What’s the best way to cut composite decking?

Composite decking should be cut with a miter saw blade that has chipping points. The best way to get the optimum performance from this type of blade is by using it at an angle, rather than perpendicular. 

This will also allow for better control and less tear-out when cutting because the teeth are sharper on one side as opposed to both sides like on a crosscut blade.

There are many different types of blades that can be used for cutting composite decking, but the best type is one with chipping points and an angle to it rather than being perpendicular.

This way, you’ll get better control over how the material cuts through as well as less tear-out because there will only be one side of the blade where there are teeth.

Additionally, composite decking can be cut with a variety of blades and not just those that have chipping points; however, it’s best to use these because they will allow you to get better control over how your cuts go through while also minimizing tear-out at the same time. 

Do composite decks get hot?

There is no definitive answer because there are a variety of composite decking materials, and some may heat up more than others. 

That being said, most composites will experience at least one-degree temperature rise when used in direct sunlight. This can be due to the material itself or just as a result of high temperatures during specific seasons (typically summer).

Final Words

I hope if you have made it this far, you will have made a decision according to your needs. However, if you are still struggling to pick the best miter saw blade for composite decking then let me help you. 

From my research, I came to a conclusion that the best blade for composite decking is the Diablo Trex blade. It has a universal fit and it can cut through any material quickly without tearing or harming your surface below.

I hope my article was helpful in some way and that you are now more able to choose what is best for your needs! 

Best of luck, be safe always
