Can You Use Sawzall Blades In A Hackzall? Experts Weigh In

Are you a DIY enthusiast or a professional contractor looking for the perfect reciprocating saw for your cutting needs?

If so, you may have come across the Milwaukee Sawzall and Hackzall saws. While both are powerful tools designed for cutting through a variety of materials, you may be wondering if their blades are interchangeable.

Can you use Sawzall blades in a Hackzall?

In this article, we’ll explore the answer to this question and provide some helpful tips on choosing the right blades for your cutting projects.

So, let’s dive in!

Can You Use Sawzall Blades In A Hackzall

The short answer is no, you cannot use Sawzall blades in a Hackzall.

While both saws are made by Milwaukee and have similar features, they are designed for different cutting tasks. The Sawzall is a full-sized reciprocating saw with a large blade used for heavy-duty demolition work and other tough cutting jobs. On the other hand, the Hackzall is a mini-recip saw designed for lighter cutting jobs in tight spaces.

The blades for these two saws are not interchangeable due to their different sizes and configurations. The Sawzall blades are larger and configured differently than the Hackzall blades, so they will not fit the Hackzall saw.

It’s important to note that while the blades are not interchangeable between these two saws, the blades for each saw are interchangeable with other reciprocating saws that have the same standard fitting.

Understanding The Differences Between Sawzall And Hackzall

When it comes to understanding the differences between Sawzall and Hackzall, it’s important to note that these two saws are designed for different cutting tasks. The Sawzall is a heavy-duty reciprocating saw that requires two hands to operate safely, while the Hackzall is a lightweight tool designed for one-handed operation.

One of the most significant differences between the two saws is their size. The Sawzall is larger and more powerful, with a longer blade and a larger motor size that can demolish any project without hesitation. It’s perfect for larger cuts that don’t require much skill, precision, or balance. Meanwhile, the Hackzall is smaller and less powerful, with a shorter blade and a smaller motor size that makes it ideal for narrow spaces and smaller objects. It’s an excellent tool for cutting smaller objects faster and easier.

Another difference between these two saws is their handle design. The Sawzall has a D-shaped handle and needs to be operated with both hands, while the Hackzall offers a pistol-like grip and can be operated with one hand. This design difference makes the Hackzall more versatile and easier to use in tight spaces.

Finally, when it comes to price, there is a difference between these two saws. The Sawzall is more widely used, so it is often more affordably priced. Meanwhile, the Hackzall’s versatility makes it slightly more expensive.

Are Sawzall Blades Compatible With Hackzall?

As mentioned above, Sawzall blades are not compatible with a Hackzall. The Sawzall blades are larger and configured differently than the Hackzall blades, so they will not fit the Hackzall saw. It’s important to use the correct blade for each saw to ensure optimal performance and safety.

However, both the Sawzall and the Hackzall use blades with a standard reciprocating saw fitting, which means that the blades for each saw can be used in other reciprocating saws with the same standard fitting. It’s essential to carry an old blade with you when purchasing a new blade to ensure that you get one with the same shaped base.

When using longer blades with a Hackzall, it can be tricky depending on the depth of material being cut. You only want a blade that is 1-2 inches longer than what you’re cutting; otherwise, it will swing side to side. Additionally, the number of teeth on a blade matters as small, tightly packed teeth are for cutting through harder materials (metal), while big, widely spaced teeth are for cutting through softer materials (wood).

Pros And Cons Of Using Sawzall Blades In A Hackzall

Using Sawzall blades in a Hackzall may seem like a cost-saving measure, but it’s not recommended. Here are some pros and cons to consider before attempting to use Sawzall blades in a Hackzall:


– Sawzall blades are generally cheaper than Hackzall blades, so using them in a Hackzall could save you money.

– Sawzall blades are designed for heavy-duty cutting, so they may be able to handle tougher materials than Hackzall blades.


– Sawzall blades are larger than Hackzall blades, so they won’t fit properly in a Hackzall saw. Attempting to force a Sawzall blade into a Hackzall could damage the saw and create safety hazards.

– Hackzall blades are specifically designed for the smaller stroke length of the Hackzall saw. Using Sawzall blades with their longer stroke length in a Hackzall could result in slower cutting times and less precision.

– Using the wrong blade for the job can be dangerous. Sawzall blades are not designed for the smaller, more precise cutting tasks that the Hackzall is designed for.

Choosing The Right Blades For Your Cutting Needs

When it comes to choosing the right reciprocating saw blade for your cutting needs, there are several factors to consider. First and foremost, you need to determine the type of material that you will be cutting. Reciprocating saw blades are designed for cutting through a wide range of materials, including wood, metal, masonry, fiberglass, and more.

The blade material is another important consideration. Bi-metal blades are the most common and versatile type of blade, made from two different types of metal for increased durability and flexibility. Carbide blades are designed for cutting through tough materials like cast iron and high-strength alloys.

The length of the blade is also important. Longer blades are better suited for cutting wider materials, while shorter blades are ideal for tight spaces and flush-cutting applications. The thickness of the blade is another factor to consider, with thicker blades offering increased durability and longer life.

The teeth-per-inch (TPI) is also an important consideration. Blades with higher TPI are ideal for cutting thinner materials, while blades with lower TPI are better suited for cutting thicker materials.

Lastly, you should consider the shape and pattern of the teeth on the blade. This can vary depending on the type of material being cut and the specific application. For example, blades with a wavy tooth pattern are ideal for cutting through wood with nails embedded in it.

Tips For Safe And Effective Cutting With A Reciprocating Saw

Reciprocating saws are powerful tools that can be dangerous if not used properly. Here are some tips for safe and effective cutting with a reciprocating saw:

1. Maintain your balance: Always use both hands when operating your reciprocating saw to maintain your balance. Keep the grips clean and free of dirt and dust. Inspect the blades before using the saw to make sure they are sharp enough for the required job.

2. Wear personal protective equipment: Always wear the proper gloves, dust mask, ear covers, and safety goggles when using a reciprocating saw. Slip-resistant footwear is also recommended.

3. Ensure proper blade settings: Never set a blade to go further than 0.32-0.64 cm deeper than the material that you cut.

4. Turn off the saw 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.

5. Use both hands: Don’t just hold the reciprocating saw with one hand. Use both hands to achieve a high level of stability. By holding the reciprocating saw with both hands, you can control it with greater ease.

6. Wear safety glasses or goggles, or a face shield (with safety glasses or goggles): Protect your eyes from flying debris by wearing safety glasses or goggles, or a face shield (with safety glasses or goggles).

By following these tips, you can ensure safe and effective cutting with a reciprocating saw. Remember to always prioritize safety when working with power tools to avoid injury or accidents.

Conclusion: Which Saw And Blades Are Best For You?

When it comes to choosing between the Sawzall and the Hackzall, it really depends on the type of cutting job you are doing. If you need a saw for heavy-duty demolition work or cutting through thick materials, the Sawzall is the way to go. Its powerful motor and robust blades make it the perfect tool for tough cutting jobs.

However, if you need a saw for lighter cutting jobs in tight spaces, the Hackzall is the better choice. Its compact size and ergonomic design make it easy to use in tight spaces, and its one-handed operation makes it ideal for pruning low-hanging branches.

When it comes to choosing blades, it’s important to choose the right blade for the job. If you need a blade for pruning, we recommend the Ax with Carbide Teeth for Pruning and Clean Wood blade. This blade is perfect for cutting through hardwood quickly and staying sharp.

Ultimately, the best saw and blades for you will depend on your specific needs and the type of cutting job you are doing. It’s always a good idea to have both a Sawzall and a Hackzall in your toolbox, along with a variety of blades for different cutting tasks.
