Can I Cut Metal With a Jigsaw?

When it comes to metalworking, a jigsaw can be a versatile tool. However, using it to cut metal requires a few essential considerations.

You might have wondered if a jigsaw is up to the task of tackling this tough material. Rest assured, with the right blade and technique, you can achieve clean cuts on various types of metal.

But before you start slicing through metal sheets or pipes, there are crucial steps to take to ensure success and safety.

Choosing the Right Blade

When cutting metal with a jigsaw, selecting the appropriate blade is crucial for achieving clean and efficient cuts. The choice of blade materials and thickness plays a significant role in the cutting process. For softer metals like aluminum or copper, a high-speed steel blade is ideal due to its durability and ability to maintain sharpness. On the other hand, for harder metals such as steel or iron, a bi-metal blade, combining high-speed steel teeth with a flexible spring steel back, is recommended for its toughness and longevity.

In addition to blade materials and thickness, adjusting the jigsaw’s speed settings is essential to ensure optimal cutting performance. Higher speeds are generally better for cutting through thicker metals, while lower speeds are suitable for thinner materials to prevent overheating and warping. Furthermore, using a lubricant like cutting oil or wax can help reduce friction, prolong blade life, and enhance cutting precision by keeping the workpiece cool and minimizing metal shavings.

Securing the Metal

To ensure stability and safety during the metal cutting process with a jigsaw, firmly clamp the metal workpiece securely in place before initiating the cuts. Clamping metal is essential to prevent the piece from shifting or vibrating during cutting, which could lead to inaccurate cuts or even accidents. Use strong clamps that can securely hold the metal without causing any damage to its surface.

In addition to clamps, magnetic guides can also be a valuable tool for securing the metal in place. These guides use powerful magnets to hold the metal firmly against the cutting surface, providing extra stability and preventing any movement while cutting. Magnetic guides are especially useful for cutting large or irregularly shaped metal pieces that may be challenging to clamp effectively.

Setting Up Your Jigsaw

Securely attach the appropriate metal-cutting blade to your jigsaw, ensuring it’s tightly fastened for optimal cutting performance.

When setting up your jigsaw for cutting metal, there are a few key considerations to bear in mind:

  1. Blade Speed: Adjust the speed settings on your jigsaw to match the requirements of cutting metal. Higher speeds are generally more effective for cutting through metal, but be cautious not to set it too high, as this can lead to overheating and premature blade wear.

  2. Material Thickness: Before you begin cutting, make sure to account for the thickness of the metal you’re working with. Thicker materials may require slower cutting speeds or multiple passes to achieve clean cuts without putting excessive strain on the blade.

  3. Blade Selection: Choose a blade specifically designed for cutting metal. These blades typically have finer teeth and are constructed from materials that can withstand the rigors of cutting through metal. Selecting the right blade for the job is crucial to achieving accurate and efficient cuts.

Cutting Techniques

Attach the metal-cutting blade securely to your jigsaw before proceeding with the cutting techniques. Blade selection is crucial for efficient metal cutting. Opt for a fine-toothed bi-metal blade to tackle various metals effectively. Consider the material thickness when choosing the blade; thicker metals require lower teeth per inch (TPI) blades to prevent overheating and ensure a smoother cut.

Adjust the cutting speed based on the metal thickness and type. For thin metals, such as sheet metal, higher speeds work well, while slower speeds are better suited for thicker materials like steel. Experiment with different cutting angles to find the most effective approach. When cutting curves, use a slower speed and pivot the jigsaw smoothly to maintain control and precision.

Remember to let the blade do the work; avoid applying excessive pressure which can lead to blade bending or breaking. By mastering these cutting techniques, you can wield your jigsaw with confidence and freedom when cutting metal.

Safety Precautions

When operating a jigsaw for cutting metal, prioritize safety precautions to ensure a secure and efficient cutting process. To keep yourself safe and your project successful, follow these essential guidelines:

  1. Safety Gear: Always wear appropriate safety gear such as safety goggles, gloves, and ear protection. Metal cutting can produce sparks and metal chips that could cause injury if they come in contact with your eyes or skin. Additionally, loud noise is a common byproduct of cutting metal, so protect your ears with the right gear.

  2. Cutting Speeds: Adjust the cutting speed of the jigsaw based on the thickness of the metal you’re cutting. Higher speeds are suitable for thinner metals, while slower speeds are more effective for thicker pieces. Using the correct speed setting won’t only ensure a smoother cut but also prolong the life of your jigsaw blades.

  3. Metal Thickness, Workspace Layout: Consider the thickness of the metal you’re cutting and make sure your workspace is properly set up. Secure the metal piece firmly in place using clamps to prevent it from moving during cutting. Ensure there’s enough space around you to maneuver the jigsaw without any obstructions.


In conclusion, cutting metal with a jigsaw is indeed possible when using the right blade and following proper techniques. With precision and care, you can achieve clean and accurate cuts for your metalworking projects.

Remember, safety is paramount, so always wear protective gear and follow safety precautions. By mastering the art of cutting metal with a jigsaw, you can unlock endless possibilities in your DIY projects.

Happy cutting!
