What Type Of Circular Saw Blade Do You Need To Cut Metal?

When it comes to cutting metal, there are a lot of options out there. However, one of the most popular tools for the job is a circular saw. Circular saws are versatile, powerful, and easy to use, making them a go-to for many DIYers and professionals alike. But when it comes to choosing the right circular saw blade for cutting metal, things can get a little confusing. In this article, we’ll take a closer look at what type of circular saw blade you need to cut metal.

Types of Circular Saw Blades

Before we dive into the specifics of metal-cutting saw blades, it’s important to understand the different types of circular saw blades available. Here are the main types:

Rip Blades: These blades have fewer teeth and are designed for making long, straight cuts. They’re not great for cutting metal, as they tend to create a lot of heat and can cause the metal to warp or become damaged.

Crosscut Blades: These blades have more teeth and are designed for making smooth, clean cuts across the grain of wood. They’re also not great for cutting metal, as they tend to get bogged down and can cause the metal to become damaged.
Combination Blades: These blades are designed for both ripping and crosscutting, and are a good all-around option for cutting wood. However, they’re not ideal for cutting metal.
Metal-Cutting Blades: These blades are specifically designed for cutting metal, and are the best option if you’re looking to cut metal with a circular saw.

What Makes a Good Metal-Cutting Blade?

So, what exactly makes a good metal-cutting blade? Here are a few key factors to consider:

Tooth Count: Metal-cutting blades typically have a lower tooth count than wood-cutting blades. This is because metal is harder and more abrasive than wood, so the teeth need to be spaced further apart to prevent the blade from getting bogged down.
Tooth Shape: The teeth on a metal-cutting blade are usually flat and square, as opposed to the angled teeth on a wood-cutting blade. This allows the blade to cut through metal more effectively.

Blade Thickness: Metal-cutting blades are usually thicker than wood-cutting blades, as they need to be able to withstand the heat and pressure of cutting through metal.
Material: Metal-cutting blades are typically made from carbide or high-speed steel, which are both durable materials that can withstand the rigors of cutting metal.

Choosing the Right Metal-Cutting Blade

Now that you know what to look for in a metal-cutting blade, how do you choose the right one for your needs? Here are a few things to consider:

Type of Metal: Different metals require different types of blades. For example, if you’re cutting aluminum, you’ll need a blade with a high tooth count and a thin kerf. If you’re cutting thicker metals like steel, you’ll need a blade with a lower tooth count and a thicker kerf.
Blade Diameter: The diameter of your blade will depend on the size of your saw and the thickness of the metal you’re cutting. Make sure to choose a blade that’s the right size for your saw.
Blade Quality: Not all metal-cutting blades are created equal. Make sure to choose a high-quality blade that will last and perform well.

Conclusion

If you’re looking to cut metal with a circular saw, it’s important to choose the right type of blade. Metal-cutting blades are specifically designed for the job, and have a number of features that make them ideal for cutting through metal. By considering factors like tooth count, tooth shape, blade thickness, and material, you can choose the right blade for your needs and get the job done quickly and easily.

Frequently Asked Questions (FAQs) – What Type Of Circular Saw Blade Do You Need To Cut Metal?

1. What is the difference between a regular saw blade and a metal cutting saw blade?

Metal cutting saw blades are designed with harder teeth and a more aggressive tooth geometry to cut through metal. Regular saw blades are not designed for cutting metal and can easily become damaged or broken when used to cut metal.

2. Can I use a wood cutting saw blade to cut metal?

No, you should never use a wood cutting saw blade to cut metal. Using a wood cutting saw blade to cut metal can cause the blade to overheat, warp, and even break. It can also cause kickback, which can be dangerous.

3. What type of metal cutting saw blade should I use for thicker metals?

For thicker metals, you should use a blade with fewer teeth per inch (TPI). This will allow the blade to remove more material with each pass and prevent the blade from becoming clogged. Blades with a TPI of 14 or less are ideal for cutting thicker metals.

4. How can I extend the life of my metal cutting saw blade?

To extend the life of your metal cutting saw blade, you should avoid forcing the blade through the metal. Let the blade do the work and use a steady, controlled feed rate. You should also use a lubricant to reduce heat and friction, and clean the blade after each use to prevent buildup.
