Different Types of Cutting Blades and Their Uses

There are a lot of factors to consider when choosing a cutting blade. It’s not a simple as many would think it is. First, you need to identify which blade your machine requires, what you plan to cut, and what type of cut you will make. 

After which, you need to determine the width of the blade that will work for the type of cut you want. Always remember that wider widths make straighter cuts in thicker materials. If you want to make a curve, your choice of blade width will depend on a lot of factors. A lot of manufacturers offer charts to help you pick the right width.

Aside from that, the number of teeth per inch will also affect the cut you will make. As a general guide, the more teeth per inch, the finer the cut will be and the fewer teeth per inch, the rougher the cut will be. 

When you have considered all the factors, including the length, width, and teeth per inch, it’s time to find the right tooth configuration for the material you are cutting. If you follow all these steps, you can guarantee to pick an ideal solution for your cutting needs, be it on stainless steel, nickel alloys, titanium, aluminium, and all steel alloys and other non-ferrous metals.

Now, let’s discuss the different types of cutting blades and their uses.

What Is a Band Saw Blade?

A band saw blade is a type of blade used to cut curves, even in thick lumber and metal. It can help optimise the process of creating cabriole legs, ripping both ferrous and non-ferrous materials to crosscut short pieces. However, a band saw is most commonly used for cutting irregular shapes. The best thing about a band saw is that it can make the smoothest cuts, and with the right blade, it can be used to cut different kinds of materials, such as wood, steel, and other metals. 

Although it is rarely the first stationary power tool that is being purchased, it is among the most versatile ones. Most band saw blades are made of alloys coated with carbon properties. So, if you’re uncertain of which type works best for your shop, don’t forget to do your research and consult the experts on what works best for you.  

Bi-Metal or Carbide: Which Is Which?  

When it comes to operating band saws, it is best to use the blade recommended for the job. Unfortunately, there is more than one option for the job, which is intimidating and overwhelming. That’s why we’ve come up with a comprehensive comparison between bi-metal and carbide blades to help you out. 

Bi-Metal Blades: What Can They Do?

If you want band saw blades that can work in a range of sawing applications and materials, bi-metal blades are the perfect tool for you. Also called M42 blades, they are known for being cost-effective and extremely efficient. These high-quality cutting blades combine the flexibility of a spring steel backer and the resistance of an M-42 high-speed steel tooth, making them ideal for cutting metal. In fact, bi-metal blades are designed to cut a wide variety of materials, including carbon steel, tool steel, structural steel, stainless steel pipes, angles, flat stocks, etc. 

Carbide Blades: What Are the Advantages?  

The carbide blades’ long service life is one of the main reasons most shops decide to make the switch. These blades’ longevity is attributed to their durability and heat resistant properties. Carbide is best suited for use in solid materials since its continuous cut faces fewer vibrations than when cutting structural or thin wall tubing. 

More than anything, coated carbide blades deliver the best performance since the thin film coating the tooth edge helps transfer the heat from the cutting edge. This protection enables the blade to stay cool, which means cutting faster and providing a much longer blade life. 

That’s why carbide blades are engineered for different uses in mind. In fact, you can use carbide blades for: 

General Purposes

Carbide blades are engineered and designed to be versatile. That’s why they are generally recommended for cutting and sawing operations where materials being cut frequently change. Their durability eliminates the need to change blades since they work well on a range of materials. 

Hard-to-Cut Objects

Steels and other metals may require a set of specialised tools for cutting. The carbide blades are optimised for aerospace alloys containing nickel, like stainless steel and Inconel. 

Types of Band Saw Blades

The types of band saw blades depend on the basic tooth variations. Among these tooth variations are the common styles like the hook, skip, and regular. What’s interesting is that while the blades look similar at first glance, they have distinct differences. Each type is suitable for a particular kind of work. 

That’s why knowing their unique features will save you time, money, and resources in the long run. Together, let’s discuss the three main types of band saw blades: 

Regular-tooth Blades 

These are the most common types of blades. They have straight-faced teeth which are evenly spaced. Usually, regular-tooth band saw blades have straight rakes and deep gullets. They are used for general cutting purposes, including cutoff or contour sawing, making them perfect for most general metals and different kinds of wood. 

Hook-tooth Blades 

Unlike regular-tooth band saw blades, hook-tooth blades have deeper gullet with larger teeth. The teeth are also widely spaced, highlighting a rake angle. All these features make faster, more coarse cuts, so they are best used in plastics, metals, thicker wood pieces, or hardwoods. Other than that, they are extremely practical in making longer cuts as the deep gullet and rake angle effectively help move the debris and cut materials out of the way. 

Skip-tooth Blades 

The previously mentioned blades have deep gullets, but the skip-tooth blades have a shallow gullet and widely spaced teeth. They have zero rake angle but have 90° tooth, allowing chips to come out cleanly. They are used for a variety of woodworking applications and other non-ferrous materials that could gum up on the blade. 

What’s More to Band Saw Blades? 

There comes a point where you would need to fix something that is broken. For example, you might need a table to fit your needs but you need it customized to your liking. Perhaps you have a hobby and want to make something tangible out of it. Doing it yourself, or DIY, is a great solution to this. When it comes to DIY projects, one of the tools that would prove useful is the circular saw.

Circular saws are handy tools for DIY enthusiasts. They can be used to break or cut down huge materials. However, they are also very challenging to use. When not used properly, they can even be dangerous. You must understand how these nifty tools work and their ins and outs.

Once you know the basics, you can proceed to master the tool. If you are planning to start a DIY project, a circular blade is not necessarily the first thing that you should buy. Yet, it can be helpful to have some knowledge about how to use it.

What is a circular saw blade?  

A circular saw is a power tool used for cutting a wide variety of materials such as wood, masonry, plastic, or metal. The blade used in this tool is called the circular saw blade. It cuts materials by spinning at drastically high speeds. These blades are usually attached to a surface such as a table. However, there are also circular saws that can be handheld.

Usually, the material to be cut is secured using other tools such as a vise. The vise is a mechanical apparatus used alongside the saw to secure an object so that it can be worked on. When the material is secured, the material is then slowly moved towards the spinning blade. As the blades have sharp teeth sticking out, they chip into the material. At high speeds, all of the blade’s teeth chip into the material. As a result, it effectively cuts it up.

The circular saw blade comes in other varieties as well. They vary in terms of the size, thickness, and how fast the blade spins. However, there are two common types of circular saw blades used by professionals and hobbyists alike. They are the carbide-tipped circular saw blades and the high-speed steel saw blades.

If you are looking to purchase a circular saw blade, knowing the difference between the two of them is extremely helpful. It can save you time, effort, and resources since buying the wrong type of circular saw blade becomes less likely to occur.

Difference Between Carbide Tipped Circular Saw Blade vs HSS Saw Blade  

The circular saw blades are one of the most essential parts of a circular saw. After all, you cannot cut your materials without the blade. However, it can get confusing to understand its uses and functions, especially if you are just starting to get into the DIY hobby.

When picking a circular blade, one of the first things to consider is the type. You need to decide if you prefer a carbide-tipped circular saw blade or a high-speed steel saw blade (HSS saw blade).

The carbide-tipped circular saw blades are blades that use other materials such as tungsten carbide or titanium carbide into the teeth’s edges. The purpose of these tips is that they can prolong the blade’s lifespan. They are extremely durable and can stay sharp for a very long time. Even though the blades themselves are made of steel, their tips made of carbide materials can remain sharp 10 to 20 times longer than tips made of steel.

On the other hand, high-speed steel saw blades usually have more teeth. The teeth’s tips are made of steel. They help the blades make a very clean cut. These blades can cut different types of materials more accurately than their counterparts, such as tubes, pipes, ingots, castings, and forgings.

Carbide tipped circular saw blades are better at handling high temperatures in the event of overheating. Thus, they are much more beginner-friendly. And in terms of price, high-speed steel saw blades are much cheaper. If you are a beginner or if you do not have the budget for a carbide-tipped saw blade, then a high-speed steel saw blade is the way to go.

Types of Circular Saw Blades and Their Uses

Circular saw blades are versatile tools. They are capable of cutting a wide variety of materials. However, they come in varying types, which are each uniquely designed to cut specific materials. Choosing the right blade can mean a huge difference in saving time, money, and resources. When you are trying to cut something, be sure to look and see if you have the right blade for the particular material you are cutting.

For starters, a general-purpose blade makes a good choice. It is a blade used for a variety of tasks. They are not designed for a specific material so they can cut almost anything efficiently. However, if you have a specific material to cut, it is better to have a blade more efficient for that job. Some of these blades are:

  • Crosscutting blades are blades used for cutting across grains of wooden materials.
  • Plywood blades have more teeth than the crosscutting blade because of the nature of the plywood.
  • Ripping blades are blades with fewer teeth meant to cut along a wood grain, not across. They typically have not more than 24 teeth.
  • Thin kerfs are blades used to make a narrow cut through wood and are not efficient in cutting tough wood.
  • Masonry blades are built differently than blades used for woodcutting because of the different properties between wood and masonry.
