Chapter 1 Why do You Need to Use the Type of Saw Blade Carefully?

Composite decking is a type of material in the decking industry. It is made by combining different materials.

Manufacturers sometimes mix the components. They add pigment and preservatives. The mixing happens by heating, forming into a board-looking length, and then cooling.

The composite decking weighs more than wood most times. Although it is not as strong as wood, however, in comparison with wood, composite decking does not rot, warp, or give fragments and does not require painting, staining, and sealing. These make composite decking a preferred choice.  

To cut, drill and fasten the composite decking, you will need standard woodworking tools. You should use carbide-tipped saw blades. This is because they stay sharp for a longer time. The blades should not overheat during cutting, as this avoids the cutting effect.

Though composite decking cutting is similar to normal woodcutting, it still requires attention to details and gaps. This is why you need to be careful with the type of saw blades you use.

Cutting composite decking could be complicated as it expands and contracts with temperature.

Working in the morning while the composite decking is still cool is advisable, as when the material heats up, it expands and becomes more pliable. This makes cutting difficult.

Chapter 2 Which Saw Blades are Suitable for Cutting Composite Flooring

Cutting composite decking is similar to cutting normal lumber; it requires special saw blades. So when cutting composite decking, it is advisable to use saw blades that are convenient and flexible for cutting. The saw blades must also be sharp.

We recommend table saw blades for this cutting task, circular saw blades, and miter saw blades. The essence of choosing these saw blades is the ease with which they help you cut composite decking cleanly and smoothly. They are sharp, which makes them save time.

Jigsaw blades are also flexible, making them suitable for making curvy designs on composite decking.

When you don’t use these saw blades, you might waste valuable products and have a negative end product.

2.1 Circular Saw Blades:

A circular saw blade is a disc with teeth that can cut composite decking utilizing a spinning motion.

You can attach them to various power saws depending on the size of the composite decking. The depth of the cut you can make on composite decking depends on the blade capacity.

The larger the saw blade, the deeper the cut. However, the blade’s speed, type, and finish cut depend on the number of teeth. Fewer teeth allow you to cut composite decking faster and more teeth will give it a finer finish.

2.2 Table Saw Blades:

The table saw blade is one of the most important blades when cutting composite decking. It’s best used with a table saw. When in a table saw, you can adjust the blade up and down to control the depth of the cut.

There are various table saw blades; the difference is the number of teeth. A particular table saw blade to cut composite decking should have a few numbers of teeth and a diameter of 7 to 9 inches.

The table saw blade made for cutting composite decking has a special tooth design that allows it to cut through composite decking.

2.3 Saw Blade: Miter Saw Blades

Miter saw blades exist in various types. These types involve different sizes and shapes to suit different purposes. Composite decking can be a little difficult to cut without chipping.

This is because the plastic veneer is thin and can easily chip. This is why miter saw blades for cutting composite decking are designed with a triple chip tooth and more teeth to make them ideal for cutting composite decking without chipping.

2.4 Saw Blade: Jigsaw Blades

These blades are versatile and offer a great service of accuracy when cutting through composite decking.

It is important to select the jigsaw blades according to the material you are cutting. It is easy to select because most manufacturers specify on the blades the type of materials you can cut with it.

The thinner ones are the best version of jigsaw blades to use for composite decking. This is because it is flexible (bendable), making it easy to make curves and patterns in composite decking.

All the saw blades above, except jigsaw blades, are capable of cutting composite decking and are similar in their functions and build. They make simple crosscuts in composite decking. The jigsaw blades are best for making curves and patterns.

The power saw they can be used with are also similar. You can use all the saw blades with a miter saw. This provides accurate and straight cuts. However, a table saw with a support extension can make all cuts easier.

The cuts performed by these saw blades come independently from the teeth rather than the whole blade. Therefore, the tooth type selection is similar to all these blades.

So, a high number of teeth and the thinness of the blades make them ideal for achieving fine and accurate cuts in composite decking. The carbide-tipped feature of these saw blades also makes them ideal for having a great cutting lifespan.

4.4 Saw Blade: Jigsaw Blades

These blades have a completely different function from the earlier-mentioned saw blades. They are more versatile in making curves, patterns, and designs in composite decking. The blade makes plunge cuts. They are also valuable in making intricate cuts due to their sizes (thin).

However, due to their thinness, they snap easily under pressure. This shows that it is not powerful and could be dangerous to use. It also has low precision while cutting through composite decking.
