But what exactly is a Sawzall saw and what can it be used for?
In this article, we’ll dive into the basics of this powerful handheld tool and explore its many uses.
From cutting through wood and metal to removing stubborn nails and even grout, a Sawzall saw is a versatile addition to any DIYer’s toolkit.
So, let’s get started and discover what makes this tool so unique and valuable.
What Is A Sawzall Saw
A Sawzall saw, also known as a reciprocating saw, is a handheld power tool that features a horizontal blade that moves back and forth to quickly cut through a variety of materials. While Sawzall is a registered trademark of Milwaukee Tools, the term is often used to describe any brand of reciprocating saw.
The design of a reciprocating saw includes a handle with a trigger and a foot at the base of the blade, similar to that of a jigsaw. The user holds or rests this foot on the surface being cut so that the tendency of the blade to push away from or pull towards the cut as the blade travels through its movement can be countered.
Reciprocating saws are commonly used in construction and demolition work, but they are also useful for DIY projects around the house. With the right blade attachment, you can use a Sawzall saw to cut through wood, metal, PVC, nails, plaster, and even ceramic tile.

With its immense power and unique design, a Sawzall saw is perfect for cuts in hard-to-reach places that would be impossible with any other saw.
It’s important to note that 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 cored 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.
The History Of The Sawzall Saw
The Sawzall saw, or reciprocating saw, was first invented by the Milwaukee Electric Tool Company in 1951. The original intention of the Sawzall was to replace or complement the hacksaw, and to be a mobile and easy-to-use tool. The Sawzall was produced to take advantage of the increasing availability of electricity at that time.
The reciprocating saw was initially an evolution from a previous saw that the Milwaukee Electric Tool Co. had made, which had a right-angle cutting mechanism. This was intended to be used by plumbers to cut materials in tight spaces. Soon after, the company released a true reciprocating saw that is still very popular today.
The reciprocating saw had changeable blades that could match certain materials, making it a very flexible tool for users. Demand for the tool increased greatly after it was released to market. Over time, modern reciprocating saws have additional features such as variable speed, battery power, and an extensive selection of quick-change blades.
Despite its humble beginnings, the reciprocating saw has become a very common tool found in construction sites and DIY projects everywhere. Advances in blade technology and batteries have helped reciprocating saws cut better than ever before. Today, they are mainly sold as tools for gutting old spaces for renovation, but they are much more versatile than that. Reciprocating saws are now used for metalworking projects, old vehicle repairs, pruning trees, and many other applications where power and maneuverability are required.
How Does A Sawzall Saw Work?
A Sawzall saw, or reciprocating saw, works by using a blade that moves back and forth in a rapid, push-pull motion. This motion is achieved through a push-and-pull (“reciprocating”) motion of the blade that is powered by a motor. The blade is designed to be easily swapped out for different tasks and can be used to cut a variety of materials.
When using a reciprocating saw, the user holds the tool with both hands and uses the blade to cut through the material. The foot at the base of the blade is used to rest on the surface being cut so that the tendency of the blade to push away from or pull towards the cut as the blade travels through its movement can be countered. This allows for more precise cuts and greater control over the tool.
Reciprocating saws are also designed to be very versatile. They can be used at an angle or overhead, making them ideal for cutting plumbing pipes or other hard-to-reach areas. Some models even have orbital action, which allows for faster cutting but may produce a rougher finish.
Types Of Blades For A Sawzall Saw
When it comes to choosing the right blade for your Sawzall saw, there are several factors to consider. The main differences between reciprocating saw blades are in teeth per inch (TPI), blade material, and blade shape.
Wood Cutting Blades are the most common type of blade and are best for cutting most types of wood, branches, and softer materials. They typically have 5 to 10 TPI and can also cut through nails. Demolition Blades, on the other hand, are thicker and have a range of 6 to 11 TPI. They are best for nail-embedded wood and heavier duty applications. You will often see demo blades with variable TPI to better cut the range of materials encountered in a demolition job.
Combination Blades are a versatile option that can cut both wood and metal. They use a variable pitch tooth configuration such as 8/11 TPI or 10/14 TPI. 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 typically have 10 to 18 TPI, but can go as high as 24 TPI. They are also used for finish cuts in wood because they leave a smooth edge.
Carbide Tipped Blades are used for cutting very hard or dense materials such as high-strength alloys, cast iron, and stainless steel. Even though they are commonly 8 TPI, the ultra-hard and durable carbide tip allows them to cut materials that destroy other blades.
Lastly, Carbide Grit Blades don’t have teeth – they have a grit surface used primarily for cutting tile and masonry.
When selecting a blade for your Sawzall saw, it’s important to consider the density of the teeth given in TPI, the gullet size, teeth geometry, and the material that the blade and teeth are made of. Reciprocating saw blades with a low TPI have larger teeth and give faster cuts while blades with higher TPI have finer teeth that give smoother cuts in wood and softer materials. Always try to have at least 3 teeth in contact with the material at all times to prevent snagging and teeth breakage, especially if you are dealing with metal and masonry.
Uses For A Sawzall Saw
There are many different uses for a Sawzall saw, making it a versatile and valuable tool to have in your arsenal. Here are some of the most common uses:
1. Demolition: One of the most popular uses for a Sawzall saw is demolition work. With the right blade attachment, you can easily cut through studs, frames, walls, pipes, and more.

2. Remodeling: If you’re planning on renovating your home, a Sawzall saw is an essential tool to have. You can use it to cut through wooden boards and frames for the placement of windows and doors. It’s also great for shaping plasterboard and cutting plastic piping for any plumbing jobs.
3. Cutting through different materials: With the right blade attachment, you can use a Sawzall saw to cut through almost any material, including wood, metal, PVC, nails, plaster, stone, ceramic tile, and even glass. This makes it a valuable tool for any construction or DIY project.
4. Pruning trees: While not as common as other uses, a Sawzall saw can also be used for pruning trees. With the right blade attachment, you can quickly and easily cut through branches and limbs.
5. Making straight and curved cuts: The back-and-forth motion of the Sawzall saw blade allows for both straight and curved cuts to be made with ease. This makes it a versatile tool for any project that requires precise cutting.
6. Tearing through timber: A Sawzall saw is great for tearing through timber joists, plasterboard, and nails to get a partition or timber extension down quicker than using hand tools.
Tips For Using A Sawzall Saw Safely
Reciprocating saws are powerful tools that can be dangerous if not used properly. Here are some tips to help you use a Sawzall saw safely:
1. Use both hands: To achieve a high level of stability, use both hands to hold the reciprocating saw. When holding a reciprocating saw with only one hand, the risk for injury increases exponentially. By holding the reciprocating saw with both hands, you can control it with greater ease and reduce the chances of it “kicking back” and causing harm.
2. Choose the right blade: Blades for reciprocating saws come in different lengths and materials for a reason. You have to choose the right blade to cut the material you’re cutting. Once you have chosen the blade, make sure that the saw is not in use and unplugged during this process. Insert the blade into the chuck and turn the chuck back to lock it in place. To double-check and make sure to insert the blade securely, give it a slight tug.
3. Maintain your balance: Always maintain your balance when using a Sawzall saw. Keep your feet apart and stand firmly on the ground to prevent slipping or falling while using the tool.
4. Wear personal protective equipment: Always wear the proper gloves, dust mask, ear covers, and safety goggles when using a Sawzall saw. Slip-resistant footwear is also recommended.
5. Ensure proper blade settings: Never set a blade to go further than 0.32-0.64 cm deeper than the material that you cut.
6. Turn off the saw for 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.
7. Use electrical safety precautions: 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.
By following these tips, you can operate your Sawzall saw safely and reduce the risk of injury or damage to yourself or others around you.
