How to Change a Portable Band Saw Blade: 7 Steps [DIY] (1)

So, you need to replace your portable band saw blade. No worries, it’s a simple process if you follow these steps:

Step #1: Turn off and unplug your portable bandsaw

Step #2: Release the spring tension on the blade

Step #3: Remove the blade from the wheels

Step #4: Clean the machine

Step #5: Install the new blade

Step #6: Re-tension the blade

Step #7: Test and cut

Let’s get into the details:

Step #1: Turn Off and Unplug Your Portable Bandsaw

For your safety, shut off and unplug your tool before getting started. This way, you can focus on the task at hand without worrying about any potential accidents.

Removing the power source from the tool prevents any electrical surges or shorts that could damage the motor or other components.

Therefore, take the time to turn off and unplug your portable band saw before proceeding with any maintenance or blade replacement.

Step #2: Release the Spring Tension on the Blade

Before removing the sharp metal strip, you’ll need to loosen the tight spring tension on it, just like releasing the pressure on a tightly coiled spring.

To do this, locate the blade tension handle on your portable band saw. This is typically positioned on the upper section or back of the tool.

Once you’ve found it, rotate the handle 180 degrees to release the tension on the blade. You should feel the pressure loosen, making it easier to remove the blade.

Step #3: Remove the Blade From the Wheels

Now it’s time to take the old blade off the wheels. Pull out the rear part and carefully remove the front part from between the guide rollers.

Start by holding the saw firmly with one hand and using the other hand to grasp the rear part of the blade. Gently pull the blade out and off the pulleys. Be careful not to let it snapback, as this can cause injury.

Next, move on to the front part of the blade. This may take a bit of maneuvering and gentle wiggling to free it from its position between the guide rollers. Take care to avoid any sharp edges while handling the blade.

Once you’ve removed the blade from the wheels, set it aside and dispose of it safely. You can now move on to the next step of installing the new blade.

Step #4: Clean the Machine

Now, clean any debris from the rubber wheels and wipe down the guide bearings to get your machine sparkling. This allows for the smooth and effortless performance of your new cutting companion.

Use a brush or cloth to meticulously clean around the guide bearings, ensuring no chips or debris are left behind. This will prevent any interference that may affect the new blade’s performance and extend the life of your portable band saw.

You must take the time to thoroughly clean the machine, as any leftover debris can lead to poor performance and even damage over time.

Step #5: Install the New Blade

You need to slot the blade between the guide rollers and align it around the pulleys to ensure proper installation.

To do this, ensure the blade sits correctly in the designated grooves between the rollers. Then, move it around the pulleys, ensuring proper alignment.

Be careful not to twist or kink the blade during installation, as this can affect its performance and even cause damage to the machine or blade.

Make sure you take your time and ensure that the blade is properly installed before beginning any cutting work. Double-check the alignment and tension of the blade to ensure it is secure and ready to use.

Step #6: Re-Tension the Blade

You’re almost ready to start cutting. Just make sure to tighten the blade correctly using the tension handle so that you can achieve smooth and precise cuts every time.

Here’s a step-by-step guide on how to re-tension the blade:

  • Make sure the blade is still properly positioned in the saw.
  • Turn the tension handle in the opposite direction of the previous step, approximately 180 degrees.
  • Apply firm but not overly tight tension to the new blade.
  • Check that the blade is still properly positioned and aligned with the saw’s guides.
  • Test the blade’s tension by gently pressing down on it with your finger – it should feel taut and not loose.

Step #7: Test and Cut

Now that the blade is properly tensioned and installed, it’s time to see the saw in action and watch your materials effortlessly transform into the exact shapes you need.

Plug the saw back in and lower it to the horizontal position. Turn on the saw and observe the blade’s movement to ensure it operates smoothly without any wobbling or jumping. This step verifies that the blade is correctly installed and ready for use.

Once you’ve confirmed that the blade is working properly, it’s time to start using it for cutting tasks. Cut a wood piece and see if it’s alright.

Our reviews provide detailed information about each product we’ve selected, including its performance, durability, and overall value. This can help you decide when to choose top-rated portable band saw blades.

How tight should a portable bandsaw blade be?

The recommended tension for a portable bandsaw blade depends on the type of blade. Most manufacturers recommend a tension of 15,000 to 20,000 psi for common carbon-steel blades.

But, bimetal, spring-steel, and carbide-tipped blades are much stronger and require a higher tension of 25,000 to 30,000 psi.

You should follow the manufacturer’s recommendations to ensure optimal performance and longevity of the blade.

How long does a portable band saw blade last?

A portable band saw blade’s lifespan can vary greatly, ranging from under six months to several years.

The longevity of the blade is impacted by several key factors, including the material being cut, the overall condition of the machine and blade, and the duration of use.

Other variables, such as the speed and performance of the saw and the feeding techniques used, can also affect the blade’s lifespan.

Ultimately, the lifespan of any blade will depend heavily on the frequency and quality of use, making it crucial to prioritize careful, efficient operation.

What is the most common portable bandsaw blade size?
