What Sawzall Blade To Use To Cut An Exhaust Pipe

Are you looking to modify your car’s exhaust system?

Whether you’re upgrading to a performance exhaust or simply replacing a damaged section, you’ll need the right tool for the job.

A Sawzall reciprocating saw is a popular choice for cutting through exhaust pipes, but with so many blade options available, it can be tough to know which one to choose.

In this article, we’ll explore the different types of Sawzall blades and provide tips for selecting the best one for cutting through your car’s exhaust pipe.

So, let’s get started!

What Sawzall Blade To Cut Exhaust Pipe

When it comes to cutting through exhaust pipes, the right Sawzall blade can make all the difference. The first thing to consider is the thickness of the metal you’ll be cutting.

For thinner metals, such as sheet metal, a blade with a higher TPI (Teeth Per Inch) is best. Look for bi-metal blades with 18-24 TPI for a finer cut.

For thicker metals like steel pipe or tubing, a blade with a lower TPI is better. Bi-metal blades with 14-18 TPI will provide the necessary rigidity and beam strength to cut through these materials.

If you’re cutting through aluminum, an 8-10 TPI blade is recommended.

It’s also important to consider the material of the blade itself. Bi-metal blades are a popular choice for their long cutting life and heat and wear resistance. Carbide-tipped blades are even more durable and can cut through tough materials like cast iron and high-strength alloys.

When selecting a Sawzall blade for cutting exhaust pipes, make sure it’s long enough to avoid getting caught on the other side of the pipe when the saw pulls back. A 6-inch bi-metal blade is a good choice for most exhaust pipe cutting jobs.

To ensure a straight and accurate cut, use blue painter’s tape to mark your cut line and guide the blade. You can also use a hose clamp on the exhaust pipe to create an even edge to cut against.

Introduction: Why Use A Sawzall For Cutting Exhaust Pipes

A reciprocating saw, also known as a Sawzall, is a versatile power tool that can cut through just about anything, including exhaust pipes. The blade of a reciprocating saw extends straight out from the end of the tool, making it easy to get into tight spaces. Unlike other cutting tools, such as grinders or cutoff wheels, a reciprocating saw doesn’t have guarding, allowing it to reach areas that other tools can’t.

When it comes to cutting exhaust pipes, a reciprocating saw with the right blade can save time and money. Using a rotary cutoff to make 74,750 cuts on 1-1/2 Sch. 40 steel pipe can cost $23,295 annually. However, using a reciprocating tool with a premium blade can reduce the cost to $8,855 annually, saving $14,440.

It’s important to note that the blade length of a reciprocating saw is not dependent on the diameter of the pipe being cut. One size fits all when it comes to reciprocating blades.

Types Of Sawzall Blades For Cutting Exhaust Pipes

There are several types of Sawzall blades that are suitable for cutting exhaust pipes.

1. Bi-metal blades: These blades are made of two types of metal, typically high-speed steel and a more flexible steel. They are durable and can withstand high heat and wear, making them a popular choice for cutting through exhaust pipes.

2. Carbide-tipped blades: These blades are even more durable than bi-metal blades and can cut through tough materials like cast iron and high-strength alloys. They have a longer lifespan than bi-metal blades but are also more expensive.

3. Diamond-coated blades: These blades have a diamond coating on the teeth, making them extremely durable and able to cut through even the toughest materials. However, they are also the most expensive type of Sawzall blade.

When selecting a Sawzall blade for cutting exhaust pipes, consider the thickness of the metal you’ll be cutting, as well as the durability and lifespan of the blade. Bi-metal blades are a good choice for most exhaust pipe cutting jobs, while carbide-tipped or diamond-coated blades may be necessary for tougher materials or more frequent use.

Blade Material And Teeth Per Inch (TPI)

The material and TPI of your Sawzall blade are crucial factors to consider when cutting exhaust pipes. The material of the blade determines its durability and ability to cut through different types of metal. Bi-metal blades are a popular choice for their long cutting life and heat and wear resistance. Carbide-tipped blades are even more durable and can cut through tough materials like cast iron and high-strength alloys.

The TPI of the blade is also an important consideration, as it determines the efficiency of the cut and the maximum blade life for the material being cut. For thinner metals like sheet metal, a blade with a higher TPI is best. Look for bi-metal blades with 18-24 TPI for a finer cut. For thicker metals like steel pipe or tubing, a blade with a lower TPI is better. Bi-metal blades with 14-18 TPI will provide the necessary rigidity and beam strength to cut through these materials.

When selecting a Sawzall blade for cutting exhaust pipes, make sure it’s long enough to avoid getting caught on the other side of the pipe when the saw pulls back. A 6-inch bi-metal blade is a good choice for most exhaust pipe cutting jobs.

Choosing The Right Blade For Your Exhaust Pipe

When it comes to choosing the right blade for your exhaust pipe, there are a few factors to consider. The first is the material of the exhaust pipe itself. If you’re cutting through thin sheet metal, a blade with a higher TPI will provide a finer cut. Look for bi-metal blades with 18-24 TPI. For thicker metals like steel pipe or tubing, a lower TPI is better. Bi-metal blades with 14-18 TPI will provide the necessary rigidity and beam strength to cut through these materials.

Another important factor to consider is the durability and wear resistance of the blade. Bi-metal blades are a popular choice for their long cutting life and heat and wear resistance. If you’re cutting through tough materials like cast iron or high-strength alloys, a carbide-tipped blade may be even more durable.

It’s also important to choose a blade that is long enough to avoid getting caught on the other side of the pipe when the saw pulls back. A 6-inch bi-metal blade is a good choice for most exhaust pipe cutting jobs.

To ensure a straight and accurate cut, use blue painter’s tape to mark your cut line and guide the blade. You can also use a hose clamp on the exhaust pipe to create an even edge to cut against.

Safety Tips For Cutting Exhaust Pipes With A Sawzall

Safety should always be your top priority when working with power tools like the Sawzall. Here are some important safety tips to keep in mind when cutting exhaust pipes:

1. Keep all bystanders away from the area you’ll be working in.

2. Wear proper ventilation and breathing protection to avoid inhaling any harmful particles.

3. Always wear protective gear such as safety glasses or goggles to protect your eyes from flying debris.

4. Be aware of any electric currents you might come in contact with and take necessary precautions.

5. Don’t wear loose clothing that could potentially get caught on the saw if it kicks back during use.

6. Don’t make your cuts too deep or you could damage other components around where you’re cutting.

7. For best results, cut only partially through the first time to create a groove for subsequent passes. This way, the remaining material doesn’t have anything to grab onto as you finish up your work and can fall away more easily instead of hanging up on something you’ve already cut through.

It’s also important to note that reciprocating saw blades come in a few standard lengths, so cutting a variety of pipe diameters doesn’t mean using a variety of blade lengths. For the most part, one size fits all.

Finally, never remove the guard on your Sawzall to get into a tight spot. When a blade breaks, it can send pieces of broken blade in every direction, putting you and others in the area at risk. Always use proper guarding and follow manufacturer’s instructions for safe use of your Sawzall.

Conclusion: Achieving A Clean Cut On Your Exhaust Pipe

In conclusion, cutting through exhaust pipes requires careful consideration of the thickness and material of the metal being cut. Choosing the right Sawzall blade with the appropriate TPI and material can make a significant difference in achieving a clean cut. To ensure accuracy, use blue painter’s tape to mark your cut line and guide the blade, and consider using a hose clamp to create an even edge to cut against. With these tips in mind, you can successfully cut through your exhaust pipe with ease.
