Suddenly you realize that your circular saw doesn’t work properly. The performance was so good before but now it’s cutting slowly. What happened?
Maybe you are feeling disappointed because you are in the middle of work. The capability of your circular saw depends on the performance of the blade. The quality of the blade and the type of materials you are cutting can affect the lifespan of your circular saw blade. It is very dangerous to use a dull blade in your circular saw.
When Should you Change a Circular Saw Blade?
A saw blade isn’t immortal. Just like most things in the world blades also get aged and demolished after a while. You can’t say when a saw blade has reached the end of its life because there is no absolute time limit. The question is when you should change a saw blade?
- Notice the sound of your circular saw. If the blade is dull, it forces the motor to give much more effort. It makes the motor slow.
- Notice how much effort you have to put on while cutting material. It’s obvious; sharp blade needs less effort than a dull blade while cutting anything.
- While cutting wood, a dull blade is likely burning the wood, or it can produce smoke.
If you notice any of this signs, then it’s time for you to change the blade.
How Saw Blade Turns Dull?
The type of material you are cutting with your saw blade can affect the lifespan of your blade. For example, hardwoods like oak or pine can dull the blade faster. However, cutting metal objects can also damage the blade.
How to Change a Circular Saw Blade?
With some simple steps, you can remove the dull blade and install a new sharp one.
Step 1: For electric circular saw, unplug the power cord and for a cordless circular saw, remove the battery from your circular saw. It’s mandatory for keeping yourself away from any injury.
Step 2: Push the saw’s arbor-lock key and rotate the blade until the locking mechanism connects.
Step 3: In addition to removing the arbor nut which is keeping the blade in place, apply a perfect size wrench. To loosen the edge keeps the wrench moving in the same direction as the blade cuts.
Step 4: To remove the blade, withdraw the saw’s upper blade guard.
Step 5: Slip the brand new blade onto the arbor. You have to make sure that the saw teeth face in the direction of rotation. If you are not sure, follow the arrow on the saw’s blade guard.
Step 6: Use the wrench again to tighten the nut. Don’t make it over tighten otherwise it will be difficult for you to loosen it while needed.
Step 7: Some saw has the diamond shaped arbor for that bestride the blade over two wood blocks and use a hammer to tap out the diamond insert from the center of the saw blade.
Safety Tips for you: If you notice that your circular saw is running slow or you have to put much pressure while using it or there is broken teeth on your saw blade than change it immediately.
Remember using a dull saw blade is extremely dangerous. You can harm yourself anytime. Another important suggestion I already said to you but as it is important I am saying it again ‘while changing a saw blade make sure you stop the power of your circular saw.’
So, no you can quickly change a circular saw blade! But don’t cut your hand or harm yourself. Always stay careful it’s mandatory! Good Luck!
