This powerful tool is capable of cutting through a variety of metals, including the notoriously tough cast iron. But before you start slicing and dicing, it’s important to know the right techniques and safety precautions to take.
In this article, we’ll explore the ins and outs of using a Sawzall to cut metal, including the types of blades to use and how to adjust your cutting technique for different thicknesses.
So grab your safety gear and let’s get started!
How Thick Of Metal Can A Sawzall Cut
The thickness of metal that a Sawzall can cut depends on a few factors, including the type of metal and the blade being used.
For thin metals, such as sheet metal or aluminum, a blade with 20-24 teeth per inch is recommended. This type of blade will provide a smooth cut without damaging the metal.
For medium thickness metals, such as steel or copper, a blade with 10-18 teeth per inch is recommended. This type of blade will provide a faster cut while still maintaining control and precision.
For very thick metals, such as cast iron or thick steel pipes, a blade with around 8 teeth per inch is recommended. This type of blade will provide the necessary power to cut through the tough material.
It’s important to note that the length of the blade also plays a role in how thick of metal can be cut. A longer blade is useful for flush cutting and can bend to enable a greater proportion of the cutting edge to ride flat. However, for cutting thinner materials, a smaller blade should be used to limit “waggle” during use.
The Basics Of Using A Sawzall To Cut Metal
When using a Sawzall to cut metal, it’s important to choose the right blade for the job. As mentioned above, the type of metal and its thickness will dictate the type of blade needed. Additionally, it’s important to keep the blade lubricated to prevent it from overheating and dulling quickly.
To begin, make sure the metal is securely clamped or held in place to prevent it from moving during the cutting process. This will ensure a straight and precise cut.
Next, select the appropriate blade for the thickness of metal being cut. Attach the blade securely to the Sawzall and turn on the tool. Begin cutting slowly and steadily, allowing the blade to do the work rather than forcing it through the metal.
As you cut, be sure to keep the blade lubricated with a lubricating stick or spray to prevent it from overheating and dulling too quickly. It’s also important to periodically check the blade for signs of wear or damage and replace it as necessary.
When cutting thicker metals, it may be necessary to use a slower cutting speed or a more powerful Sawzall with higher amperage or voltage. Always follow manufacturer instructions and safety guidelines when using power tools, and wear appropriate safety gear such as eye protection and gloves.
Choosing The Right Blade For The Job
When choosing a blade for your Sawzall, it’s important to consider the type of metal you’ll be cutting and the thickness of the material. The recommended teeth per inch (TPI) for the blade will vary depending on the thickness of the metal.
For thin metals, such as sheet metal or aluminum, a blade with 20-24 TPI is recommended. This type of blade will provide a smooth cut without damaging the metal.
For medium thickness metals, such as steel or copper, a blade with 10-18 TPI is recommended. This type of blade will provide a faster cut while still maintaining control and precision.
For very thick metals, such as cast iron or thick steel pipes, a blade with around 8 TPI is recommended. This type of blade will provide the necessary power to cut through the tough material.
It’s also important to consider the length of the blade when choosing the right one for your job. A longer blade is useful for flush cutting and can bend to enable a greater proportion of the cutting edge to ride flat. However, for cutting thinner materials, a smaller blade should be used to limit “waggle” during use.
In addition to TPI and length, consider the material of the blade. Carbide teeth blades are recommended for cutting through metal as they are durable and can withstand high temperatures.
Investing in a bi-metal saw blade set that contains a selection of blades suitable for a range of commonly performed projects is also a worthwhile investment. This will ensure that you always have the right blade for the job at hand.
By choosing the right blade for your Sawzall, you’ll be able to cut through metal with ease and precision, no matter what thickness or type of metal you’re working with.
Safety Precautions For Metal Cutting With A Sawzall
When using a Sawzall to cut metal, it is important to take proper safety precautions to avoid injury. Here are some safety tips to keep in mind:
1. Wear appropriate personal protective equipment, including impact-resistant safety goggles, sturdy gloves, and slip-resistant footwear. This will protect you from flying offcuts, chips, and other debris.
2. Select the correct blade for the metal being cut. Using the wrong blade can cause damage to the blade or the material being cut, and can also pose a safety hazard.
3. Insert the blade into the saw in a way that best suits the application. If cutting through a material that is flush to the floor, it can be useful to insert the blade with the teeth facing upwards and then switch the orientation of the tool (flip it upside-down) so the handle does not get in the way.
4. Set the saw to a slower speed than for wood cutting. This will extend the blade life and provide more control and precision.
5. Adjust the shoe to ensure it is set at the most appropriate point on the blade. This will help guide the blade until it gains purchase in the metal.
6. Place the blade where the cut will be, using the shoe as a pivot or fulcrum to guide it until it gains purchase in the metal. Slowly squeeze the trigger and keep a firm hold on the tool housing.
7. Changing the cutting angle by lowering or raising your hand (in relation to the workpiece) can speed up the cutting time.
8. When the cut is complete, let go of the trigger and withdraw the blade back through the cut. Prolonging the life of reciprocating saw blades by straightening them if they become buckled or repurposing them for use cutting plastics.
By following these safety precautions, you can safely and effectively use a Sawzall to cut metal of various thicknesses. Remember to always prioritize safety when using power tools, and never hesitate to ask for help or guidance if you are unsure about how to use a tool properly.
Techniques For Cutting Thin Metal With A Sawzall
When cutting thin metal with a Sawzall, it’s important to choose the right blade and use proper technique to ensure a clean and accurate cut. Here are some techniques to keep in mind:
1. Choose the right blade: For thin metals, a blade with 20-24 teeth per inch is recommended. Make sure to select a blade that is appropriate for the type of metal you will be cutting.
2. Use the right speed: Set the speed of your Sawzall to a moderate level for thin metals. This will ensure that you have enough power to cut through the metal without damaging it.
3. Secure the metal: Clamp the metal securely in place before cutting. This will prevent it from moving and ensure a straight and accurate cut.
4. Start slowly: Begin cutting slowly to establish a groove in the metal. Once you have a groove, you can increase the speed and continue cutting.
5. Keep the blade perpendicular: Keep the blade perpendicular to the surface of the metal as you cut. This will ensure that you get a clean and accurate cut without damaging the metal.
6. Watch for sparks: When cutting metals, sparks can fly off the blade. Make sure to wear appropriate safety gear, such as safety glasses, to protect your eyes from flying debris.
By following these techniques, you can achieve a clean and accurate cut when using a Sawzall to cut thin metal.
Adjusting Your Technique For Thicker Metal
When cutting thicker metals with a Sawzall, it’s important to adjust your technique to ensure a safe and effective cut. Thicker metals require more power and control, so it’s important to use a blade with the appropriate teeth per inch, as mentioned above.
In addition to using the right blade, it’s also important to pay attention to the speed of your cut. Thicker metals require a slower cut to prevent the blade from overheating or getting stuck in the material. Take your time and let the saw do the work, rather than trying to force the blade through too quickly.
Another key factor in cutting thicker metals is ensuring that the material is properly secured. Thicker metals can be heavier and more difficult to handle, so it’s important to use clamps or other tools to keep the material in place while cutting. This will prevent the material from shifting or moving during the cut, which can be dangerous and lead to an inaccurate cut.
Finally, it’s important to use proper safety equipment when cutting thicker metals. This includes wearing gloves, eye protection, and ear protection. Thicker metals can produce more sparks and debris, which can be dangerous if not properly protected against.
By following these tips and adjusting your technique for thicker metals, you can safely and effectively use a Sawzall to cut through even the toughest materials. Remember to always use caution and prioritize safety when working with power tools.
Tips For Cutting Cast Iron With A Sawzall
Cutting cast iron with a Sawzall can be efficient if done correctly. Here are some tips for cutting cast iron with a Sawzall:
1. Use a blade specifically designed for cutting cast iron. A diamond blade is recommended as it can cut through the material quickly without dulling.
2. Mark the cutting line on the surface of the cast iron using a carpenter’s pencil.
3. Secure the blade in the end of the Sawzall and make sure it is tight.
4. Squeeze the trigger and slowly lower the moving blade onto the line at one end of the section of cast iron, holding the blade roughly at a 45-degree angle to the surface of the cast iron.
5. Wait for the blade to make an indentation into the cast iron before applying a little force on the saw to move the saw blade along the marked line.
6. Continue until the cut is made completely along the marked line.
7. Keep your speed down and use a fair amount of pressure. High speed and light pressure create more friction which can degrade cutting edges.
8. Use a carbide blade if you don’t have access to a diamond blade, but be aware that it may not last as long and may require more effort to cut through the material.
By following these tips, you can effectively cut through cast iron with a Sawzall and complete your project with ease.
