If you’re in the construction or demolition industry, chances are you’ve heard of a Sawzall. But what exactly is a Sawzall blade?
This type of blade is used in reciprocating saws to achieve a push-and-pull cutting motion, making it a versatile tool for cutting through a variety of materials. From wood to metal, there are different types of Sawzall blades designed for specific cutting applications.
In this article, we’ll explore the different types of Sawzall blades and help you choose the best one for your next project. So, let’s dive in and learn more about this essential tool in the construction and demolition world.
What Is A Sawzall Blade
A Sawzall blade, also known as a reciprocating saw blade, is a cutting tool used in reciprocating saws to achieve a back-and-forth cutting motion. This type of blade is commonly used in construction and demolition work to cut through a variety of materials, including wood, metal, and even masonry.
There are several types of Sawzall blades available on the market, each designed for specific cutting applications. For example, wood cutting blades typically have 5 to 10 teeth per inch (TPI) and are best for cutting most types of wood, branches, and softer materials. Demolition blades, on the other hand, are thicker and have a higher TPI range from 6 to 11 TPI. They are best for nail-embedded wood and heavier duty applications.
Combination blades use a variable pitch tooth configuration and can cut both wood and metal. They are a good choice for many jobs because they cut a wide variety of materials. Metal cutting blades have more teeth per inch for cutting harder, denser materials. They are typically 10 to 18 TPI but can go as high as 24 TPI.
Carbide tipped blades are designed for cutting very hard or dense materials such as high-strength alloys, cast iron, and stainless steel. They are commonly 8 TPI but have an ultra-hard and durable carbide tip that allows them to cut materials that destroy other blades. Carbide grit blades don’t have teeth – they have a grit surface used primarily for cutting tile and masonry.
What Is A Sawzall And How Does It Work?
A Sawzall, also known as a reciprocating saw, is a powerful cutting tool that uses a back-and-forth motion to cut through a variety of materials. The name Sawzall is actually a brand name for a reciprocating saw made by Milwaukee, but the term has become synonymous with any reciprocating saw.
The Sawzall works by rocking a long, thin blade back and forth against the material to be cut. The blade is held in place by a clamp and moves rapidly in and out of the saw’s housing. This motion allows the blade to quickly cut through the material, making it an efficient and versatile tool.
Not all Sawzall or reciprocating saws are created equal. They come in a variety of designs with different power outputs usually measured in either amps or volts. Just about every tool manufacturer makes their own version of a Sawzall in either corded or battery-powered configurations.
Blades are easy to swap in and out of the saw in a matter of seconds. And it’s the blade that makes the saw so unique and versatile. What can you cut with a Sawzall? Just about any material as long as you have the correct blade and a strong enough saw.
To choose the proper blade for the material you need to cut, there are many blade characteristics to consider. In general, this includes the blade material, length, width, thickness, and teeth-per-inch (TPI). For specific cut types, blade shape, tooth shape, kerf-width, gullet, and tooth pattern can be selected.
Understanding The Different Types Of Sawzall Blades
When it comes to Sawzall blades, there are several different types available, each designed for specific cutting applications. One of the most important factors to consider when choosing a Sawzall blade is the tooth material.
Wood cutting blades typically have 5 to 10 teeth per inch (TPI) and are best for cutting most types of wood, branches, and softer materials. These blades are ideal for pruning trees or cutting lumber for a DIY project. Demolition blades, on the other hand, are thicker and have a higher TPI range from 6 to 11 TPI. They are best for nail-embedded wood and heavier duty applications, such as demolition work.
Combination blades use a variable pitch tooth configuration and can cut both wood and metal. They are a good choice for many jobs because they cut a wide variety of materials. However, if you are primarily cutting metal, you may want to consider using a metal cutting blade instead.
Metal cutting blades have more teeth per inch for cutting harder, denser materials. They are typically 10 to 18 TPI but can go as high as 24 TPI. These blades are ideal for cutting through pipes, sheet metal, and other tough materials.
If you need to cut very hard or dense materials such as high-strength alloys, cast iron, or stainless steel, you may want to consider using a carbide tipped blade. These blades have an ultra-hard and durable carbide tip that allows them to cut through materials that would destroy other blades. They are commonly 8 TPI and are ideal for heavy-duty industrial applications.
Finally, if you need to cut tile or masonry, you may want to consider using a carbide grit blade. These blades don’t have teeth – they have a grit surface that grinds through the material. They are ideal for cutting through ceramic tile, concrete blocks, and other masonry materials.
Choosing The Right Sawzall Blade For Your Project
Choosing the right Sawzall blade for your project is crucial to achieving a clean and efficient cut. Here are some factors to consider when selecting a Sawzall blade:
1. Material – The material you will be cutting determines the type of blade you should use. For example, if you are cutting wood, you should use a wood cutting blade with a lower TPI. If you are cutting metal, you should use a metal cutting blade with a higher TPI.
2. Teeth per inch (TPI) – The TPI of a Sawzall blade determines how quickly it will cut through the material. Blades with fewer teeth per inch cut faster but leave a rougher finish, while blades with more teeth per inch cut slower but leave a smoother finish.
3. Blade length – The length of the blade should be appropriate for the thickness of the material you will be cutting. A longer blade is better for thicker materials, while a shorter blade is better for thinner materials.
4. Blade thickness – The thickness of the blade should also be appropriate for the material you will be cutting. Thicker blades are better for heavier duty applications, while thinner blades are better for lighter duty applications.
5. Blade shape – The shape of the blade should also be considered when choosing a Sawzall blade. Straight blades are best for making straight cuts, while curved blades are best for making curved cuts.
By considering these factors, you can choose the right Sawzall blade for your project and achieve a clean and efficient cut every time.
Tips For Using A Sawzall Safely And Effectively
When using a Sawzall or any other reciprocating saw, it is important to take proper safety precautions. Here are some tips to ensure you are using your saw safely and effectively:
1. Wear personal protective equipment (PPE): Always wear the proper PPE, including gloves, dust mask, ear covers, slip-resistant footwear, and safety goggles when using a reciprocating saw.
2. Inspect the blades prior to using the saw: Make sure the blade is sharp enough for the required job and that it is securely inserted into the chuck. Give the blade a slight tug to ensure it is tightly inserted and won’t come out.
3. Maintain electrical safety: Never use an electric reciprocating saw during wet conditions. Use the saw with Ground Fault Circuit Interrupter (GFCI) protected outlets or extension cords. Check the tool cord for damage prior to use, and if a problem is detected, do not use it.
4. Ensure proper blade settings: Never set a blade to go further than 0.32-0.64 cm deeper than the material that you cut.
5. Turn the saw off to perform maintenance: When changing or cleaning reciprocating saw blades, turn off and unplug the tool. Never put the saw down until the motor has completely stopped.
6. Choose the right blade for the job: Different blades are designed for different materials, so make sure you choose the right one for your project. The blade for wood from tree branches and a blade for cutting through ceramics will be vastly different.
7. Use a powerful saw with a good blade: When cutting through hard, dense materials like metal or concrete, you need both the correct blade and also a powerful saw. This is usually shown as amperage if the saw is corded or volts if it has a battery. The higher the number, the more power the Sawzall typically has.
By following these tips, you can ensure that you are using your Sawzall safely and effectively for any project you tackle. Remember to always prioritize safety when working with power tools.
