Chances are, you have been using the same blade for your circular saw for months. Have you ever wondered if it was time to change that blade?

You might be surprised by how often people need to change their blades. It is not recommended to wait until your blade is completely dull before changing it, as this can lead to a broken blade or other injuries. 

In order for the saw blades on your miter saw and circular saws to stay sharp, they should be changed every 6-8 hours of use. This might seem like an excessive amount of time but think about all the cutting you do in one day.

Especially if you’re doing different types of cuts, and then think about how much longer those cuts would take with a dull blade.

Why Do You Need To Change The Circular Miter Saw?

There are many reasons why people need to change their circular miter saw.

One of the worst things about a circular saw is that it is hard to get accurate cuts with them, and this can lead to mistakes when you are building something like furniture or even just cutting pieces for your art project.

If you have one at home but do not use it often because of its lack of accuracy then I recommend upgrading so that if there is ever an occasion where precision matters.

Such as in construction work or creating complex frames from woodworking materials, then you will be ready. You will not regret getting rid of your old one after experiencing what newer models offer.

They cut much more smoothly than older ones do which means less time spent trying to adjust each.

A circular saw is a powerful tool for cutting lumber, but it can be time-consuming and difficult.

It is not hard to understand why people gravitate towards the quicker method of using an electric jigsaw or just simply a handsaw instead.

Step By Step Guide To Replacing The Circular Miter Saw Blade

Circular saws are a fantastic tool for cutting wood, but they can be dangerous if you do not know all of the safety measures.

I am going to teach you how to change and replace blades on your circular saw in order to best protect yourself from injury when using it.

  • Removing The Battery

It’s vital that all-electric tools are switched off when not in use of any kind, especially those plugged into outlets. That includes if it has been accidentally left on from being unplugged by mistake.

Even without using it at all, electricity can still run through loose wires until they heat up enough and cause injury while handling them.

To avoid these dangers altogether: Disconnecting the power supply is key for whichever type of blade-based cutting equipment you’re working with.

  • Arbour Nut Should Be Removed

Take off that blade guard and make sure you have a safe surface. If it has an automatic safety lock, engage it for even more protection.

The blade can be locked in place so that you do not have to worry about the blade coming loose and spinning around when loosening it.

The blade should be held firmly between a wooden surface and the table. Make sure you have your safety lock completely secured so it stays in place for the next step.

  • The Remove The Worn Blade

As the blade turns clockwise, you will want to turn your wrench counterclockwise. As long as it is a snug fit and does not move in any direction other than up or down, then keep turning until tight enough.

Insert the key into a small hole, twist it clockwise to remove, and unscrew.

Pull out two thin metal tabs on either side of the blade opening while holding onto one end with your thumb. Until they pop open like wings from the horizontal position so that you can access what’s inside.

  • Now Replace The Blade

Hurry up and get the old blade out!

You need to put in a new one, there is no time for that. It is important not only because it will make your saw last longer. But also because you can’t cut straight with an old or dull blade.

  • Check The New Blade

To power on the machine, remove any obstacles that might be blocking the outlet and plug in your circular saw.

Turn it over to examine if there is a battery compartment from which you can replace or insert fresh batteries. If not, look for other outlets nearby so you don’t have to strain yourself too much just yet.

Replacing The Blade Of Craftsman Circular Saw

Change Craftsman Circular Saw Blade

When it comes to cutting wood, plastics or anything in-between a Craftsman circular saw is the best tool for the job.

These portable power tools can be powered by either battery or cord and have replaceable lathe blades with several sharp teeth that rotate at high speeds.

But how can you change its blade? Follow the steps

Step 1: A saw is a dangerous tool. Turn it off and unplug the power cable from the wall or remove the battery for safety.

Step 2: Place the saw on your work table so that it’s raised and the blade rests next to your hand.

Step 3: To lock the blade in place, press the “Spindle Lock” button on top of your saw. This will prevent any unexpected movement from happening while you cut through a board.

Step 4: With your blade wrenches at the ready, insert the appropriate one into the center of the bolt and turn it to loosen.

Step 5: Remove bolts by first sliding them to one side with an open-end wrench. They are fairly easy to loosen. Next, remove the inner nut using pliers or channel locks applied directly onto edges for leverage against counter-torque while turning anticlockwise until completely removed.

Step 6: Carefully slide the blade out of its holder, and then through to completely release it from the saw. This will allow you to remove any excess debris or buildup off of either side before storing your tool for safekeeping.

Warning! Take Care Of The Following:

New blades are always a startup cost for circular saws, but if you have lost the blade key to your Craftsman. Or another brand of circular saw and needs an emergency replacement because it’s Sunday night at 10:00pmthen there is hope.

A hex wrench can be used in place of the blade key on some models like this one from Husky Tools. You will have no problem unlocking that baby after you put a new blade inside.

Changing The Ryobi Circular Saw Blade

Changing The Ryobi Circular Saw Blade

A circular saw blade is a rotating disc with teeth, It has been called the workhorse of woodworkers. And for good reason!

It can slice through everything from lumber to plywood like butter and even makes cutting curves in sheet metal easier as well.

So when you need to change your Ryobi Circular Saw Blade, follow these simple steps:

Step 1: As a safety precaution, always switch off your saw before switching it on again or moving to another location.

This way too will prevent unforeseen accidents like when one is unaware of the extension cord lying in wait nearby. While cutting something with their tool still plugged into an outlet somewhere else entirely.

Step 2: When you press and hold the spindle lock button, it prevents your blade from moving. It is located above the blade on top of the middle part of your saw.

So that when you are cutting vertically down something like a tree trunk or large branch with one hand gripping tightly onto both handles to prevent twisting/sliding and use only the thumb for pressure against the trigger. This will help reduce injury.

Step 3: Loosen the center screw of your saw blade and remove it while pushing down on the spindle lock button.

Step 4: Place the blade in a vise, making sure to securely clamp it so that you do not accidentally damage the edge. If there are any washers already on your shaft, remove them and set them aside for later use. They will be reused when installing the new blades.

Step 5: Take up the blade guard, then carefully remove it. Take care not to touch any of the sharp bits on that side. And try not to let your fingers get in between where you are holding things at either end.

Step 6: Wiping just one small spot can ensure you will have fewer binding issues down the line. Because this little bit will be spread around when sawing through different surfaces.

Step 7: Lubricate the blade with a drop of oil before cutting through any material.

Step 8: Place the blade on the spindle and lower it into place. Gently, close both blades to cut wood efficiently with safety in mind!

Step 9: Install the blade screw in one end of your spindle and use an adjustable wrench at the other side for tightening purposes.
