How to Change A Bandsaw Blade: 10 Easy Steps

The Bandsaw is a powerful tool found in any woodworking shop. It can help you do complicated tasks with ease, but if the blade isn’t sharp, then it’s not going to matter how expensive that saw was!

The blade of your Bandsaw might be one of the trickiest tools to change, but it’s not impossible! If you put in a little bit more time and effort than usual into this task, then replacing your blades will become easier for future jobs.

There are many ways to change a bandsaw blade, but this is the simplest and quickest way. To get started you will need some safety glasses because there could be metal shards that fly off when removing or installing the old blade.

Learn How to Change A Bandsaw Blade Following 10 Easy Steps

A blade is like a sharpened tooth in the mouth of your saw. It has to be maintained, cleaned, and pressed up against the right spot for it to work correctly.

A lot of people don’t realize this but you have to know what adjustments are required on both sides: not just with how tightly your screws go into place or even where they need tightening; if you want things done right then you’ll also need an idea about which blades will cut better than others when cutting below standard through-sawing conditions

A blade is as important as having teeth in our mouths – without them, we couldn’t bite food properly (except maybe soup). For many woodworkers that means installing new blades once their old ones start getting duller and more brittle.

Many people fail to realize the importance of changing a bandsaw blade. This is why I put together this guide that outlines how you can change it easily and avoid damaging your machine in the process. Let’s get started…

Step 01: Unplug the machine

A dangerous mistake to make when changing the blade on a bandsaw is not disconnecting it from electricity. This means that you need to open up the circuit breaker or take out your plugin for this device not to turn on while dealing with these delicate components.

Otherwise, serious harm can come about both physically and financially by breaking an expensive saw.

Step 02: Open the wheel guards or cabinets

As you disconnect the saw from the power, open up both its top and bottom wheel guards. You will find two tires or wheels connected with a band saw blade: one on each side of it.

In these steps, we are going to change that old blade for a new sharper one! Properly clean inside part of cabinets using any dry cloth so there is no dust or chips leftover then close them again when done.

Step 03: Retract all the band saw blade guides

So, you want to make the blade guides as wide apart from each other as possible. First of all, pull out those carbide guide blocks until they are very loose, and then use a hex wrench with an anti-clockwise motion (the opposite way that it goes in) to loosen up that set screw for your blade support bearing below each one.

Next, take back the whole thing by turning this small tension knob on both sides which will tighten everything right up again while also making them wider than before.

Step 04: Unwind the blade

After retracting the blade guards, loosen up on tension by turning the knob located at top of the upper wheel guard.

Turn vertically-shafted adjustment knob counterclockwise until pliable/softened and it will release that tension from holding in place for your saw’s blade to move more freely with less resistance as you cut through the material.

Step 05: Remove the rear and under table blade guard

Once you’ve found the screws that keep the blade guard in place, unscrew them so it slides out of your way.

The rear blade has a lot to offer but is not for everyone – some people find they are more comfortable with other types and styles of bandsaw blades than what this one offers.

Your new table is not just for cutting but also the place where you can make all of your small adjustments. Once, loosen some screws to take out that pesky blade guard and add on those adjustment wheels.

Be careful when you reach the under-table blade guard below this hole. The screw that keeps it around your feet is difficult to see and can be tricky to unscrew with fingers, so use a screwdriver for that one.

Step 06: Take away the bandsaw blade

Before replacing the blade on your band saw, you’ll need to remove the blade guides and whole guide block assembly. You should also be careful when removing a table leveling pin before installing new blades because it is easy to lose or misplace them during installation.

To clean the blade, you should place it on a table with the cutting edge pointing away from your body. Keep leather gloves and an eye mask handy for when you pull out the knife after use to avoid any accidents! Store this blade in a safe location so that no one else can touch or harm themselves.

Step 07: Clean the wheels

To make sure your bandsaw is in the best shape, carefully inspect its tires. You should be checking to see if there are any dust particles or rust on them and that they’re clear of all small unwanted debris too! A dirty tire can cause interference with a new blade and negatively affect performance by putting scratches into it for example.

I found a really cool way to remove the dirt from my carpets. To start, just use your small steel roller as a scraper and place it on the wheel with one hand and rotate manually with another hand.

Once you’re done scraping all of that sticky dirt out, go ahead and wipe up any leftover dust using some dry cloths.

Step 08: Placing the new blade

To get an even cut, make sure you have the appropriate blade. Remember that expensive blades aren’t necessary but it’s important to buy sharp ones for a precise operation.

You should also purchase some at once and each blade has 3 teeth per inch.

Now, you can start adjusting the blade by rotating that vertically shafted tension knob. Clockwise and counterclockwise rotations will help to center it on top of the upper wheel.

You will find tension marks on your bandsaw for various blades. If you are using a blade that is two inches wide, provide medium-tension to keep the saw blade firmly in place as it cuts through wood or metal.

Step 09: Adjust the Tilt

Loosen the wing nut to unlock and adjust the tilt of your upper drive wheel. You can do this by turning it with a slight grip, just be careful not to overdo it or you will end up knocking everything down. With that being said feel free to turn as much as is comfortable for you.

After adjusting tighten the nut again or else lower items may fall out at some point in time when they are tilted too far back on their own accord.

Step 10: Put everything back again

You are going to feel great, knowing that you just fixed the blade. You need to start by taking everything off of it and then adjusting how much space is between your blades with a hex screwdriver before putting anything back on its original position until all screws have been tightened down once again.

When you need to replace a blade tension, be sure that the guide blocks barely touch it. Do not flex or bend the new blade either – this can cause major issues.

Once your replacement is in place and mounted correctly on its thrust bearing, slide back into position with a white plastic round plate for extra protection and insert leveling pin at end of the table if necessary.

To make sure your machine is functioning properly, start by turning it on. Make adjustments to the blade using the wheel cabinets and power source if necessary until you notice a smooth rotation.


When should I change my band saw blade?

You may want to think about changing your blade because you’re starting to notice it getting louder or squeaking, which could lead the way for a slow-cutting experience.

Final words

There is no such thing as a dull blade, and all bandsaw problems are caused by the user. Knowing how to change a bandsaw blade can help you get rid of these issues quickly.
