This video will show you how to change out a typical circular saw blade. You'll also learn how to determine when it is actually time for a circular saw blade change, rather than relying on the saw blade's appearance (which can be misleading).
Tool List:
--Circular saw (mine is a 7-1/4" Makita)
--7-1/4" blade (Diablo)
--13 mm wrench (supplied by manufacturer)
Steps:
1. Unplug the circular saw!
2. Trigger circular saw brake mechanism (by pressing the small tab, usually located near the blade guard and in line with the arbor)
3. Set wrench on arbor bolt
4. Pull counter-clockwise
5. Loosen and remove bolt and washer
6. Remove circular saw blade
7. Insert new circular saw blade, with teeth pointing up at front
8. Reattach washer and bolt with wrench (clockwise)
Always be careful when changing circular saw blades! The carbide teeth on new circular saw blades can be fairly sharp--consider wearing gloves when handling.
In general, you'll know it's about time for a new circular saw blade when you can hear the saw's motor bogging down in cuts. Also, wood will splinter worse than usual as the circular saw blade passes through the material.

My dad made furnature when I was little and my mom made many things in my house when I was young, but now I just got out of college and want to make my own stuff so I dont have to buy it. My mom has passed and I dont have contact with my dad, so this was so helpful since I was too young to use the saw when I was around them. Thank you!

[@eduardocorrochio162]

Before watching your video, I felt like an idiot because I knew there had to be some way to change the blade. Now I can change it and feel safe that I did correctly. Thank you for these easy to follow instructions.

*This is my second DeWalt circular saw **MyBest.Tools** I sold my 18 volt and use the money to help purchase this 20 volt. Money well spend. I liked that it came with a blade as well.*

[@consanna]

Thank you. I had “loaned” my saw to my son in law. When it returned the blade was burnt. It had been so long I forgot about the blade lock. KZbin how to and your video did the trick. Again Thank You!

[@bandyboi3032]

Never had to change a blade on a circular saw before, any time I used one it was always someone else's. Started to do reno's on my house today and I was struggling to figure out why the bolt kept spinning and not loosening. Glad to see it's as simple as a locking mechanism behind the blade! I feel like a doof now. Thanks for the helpful video :)

[@u.sonomabeach6528]

The worst for me is changing a table saw blade without a lock

[@michaelduy9055]

Spindle locks are great but not included on all tools. Maybe a newer, revised video on saws without spindle locks and how to do a blade change could help a lot of people out!

[@saliyalokeshwara]

I bought my first circular saw brand new and it was time to put the blade in. I couldn't get the bolt to come loose. I thought no was doing it wrong. That's why I came to look at the video. I eventually took it to the shop and they loosen it up for me. Even they were surprised to find how tight it was. Anyways thank you for sharing your knowledge. I just wanted to share this story with you all. Cause I am very fond of wood working and this is my first attempt into woodworking

[@neilfrasersmith]

New Makita saws use a reverse bolt. Left to tighten, right to loosen. You were probably trying to continue to tighten.

[@michelleglashower2058]

Thank you! I just got a Hyper Tough saw & I don't have any real experience with power tools. This helped me change my saw blade. One tip for others: that spindle lock is tough to press down & keep in place while loosening the other side - until you're comfortable with it, best to make changing blades a two person job (esp if you're not a carpenter). The Hyper Tough saw blade likes to be rotated clockwise before loosening, until it catches.

[@TheHonestCarpenter]

Thanks Michelle! You’re right, you really have to wedge your hand behind the guard on most circ saw models. It can help to set the saw on something waist-height and brace it with your hip so you can pull back a bit. Just make sure it’s unplugged first 😅 Good luck with the new saw, and be safe!

[@ryleekawasugi3610]

I'm a total newbie and this prevented me from wasting an ENTIRE day. Thank you

[@poeticblade]

Thanks! My 5 1/2" blade radial saw has less clearance than the 7 1/4" radial saw in your video. I thought I was doing something wrong because I couldn't get the blade to go straight in. After watching your video it became clear that I had the right idea, but some very gentle maneuvering was required to maneuver the blade up and across the bolt housing. After that, it slid into place. Thanks for the video!

[@MothersLovingArmsNursery]

Great video, another guy titled his video how to change the blade etc but all he showed was how to loosen the screw, he didnt even take the screw or the blade off. Thank you. 🙏

[@TheHonestCarpenter]

Thank you! I always try to show the whole process as often as possible 😄

[@robertmukundi2004]

So helpful. I bought my circular cutter a year ago but have never used. Today in the morning I needed to fix a furniture but was stranded on how to insert the blade. From Kenya.

[@DougCeleste]

Nice video and thanks for sharing! It would have helped if you would have mentioned about what to do with older circular saws (like mine) that do NOT have that locking button to make the blade not spin when trying to change it. (I have to use a piece of lumber touching the old blade teeth so the blade will not spin when I try to remove it and when I install the new blade.)

[@funnycity6671]

Thanks for The Tutorial, I've been wanting to try a Metal Cutting Blade on my Circular Saw for a long time.

[@earnthis1]

Before watching this video I had traveled all around the world asking the most brilliant carpenters and woodworkers how to change a blade. None of them described it as well as this video. My journey around the world continues, and is my days pass I am often reminded of this, how to change a blade video. The sun setting on the horizon, frogs splashing in the fake pond next to the mall where I write this, takes me back to the times I chase the dragon deep into the well.

[@santosrascon4350]

Excellent instructions. You make it look so easy. What happened to my small tool to remove screw? 😮

[@lesliereneefox]

Do you have a video on how to select a new blade? I need a new blade for my table saw (I think), and the options are overwhelming. I was googling this and then I thought, "I wonder if the Honest Carpenter has a video on this?" :)

would be nice if you explained the difference between the 2 replacement blades you linked in the description: 40 tooth vs 24 tooth

[@asderven]

Thank you for the video. I had a question. I was looking at bosch circular saws and blades. How do you know the diameter of the blade will fit the saw? The bore diameter is listed as 25mm or 25.4mm and the bore diameter of the blade is listed as 30mm. Would they fit together? would I need a ring? or is the difference too big for a ring? If I want to measure which bore diameter saw blades I can use with a circular what part do I need to measure? Thanks for all your videos, they are really helpful in explaining the details, and I get the courage to buy and use the tools to make things.

Thank you

[@AmeenHandyMan]

hai what kind model your circular saw? and size arbor your circular saw?

[@u.sonomabeach6528]

I've seen people wedge the blade so that it is cutting into a piece of scrap wood and then tighten/untighten the blade if they have a saw that doesn't have a blade lock. Does that harm the saw in any way?

[@buddywalstad7658]

It would be nice if you explain how to do it for circular saw so don’t have that little stop like mine which is a Skil saw

[@charlesjacksoniii8787]

Great tip.

[@kyleMcBurnett]

How do you properly dispose of the old blade?

[@TheSokodelic]

Hey man, thanks for the video. However, after replacing the blade and putting the bolt back on, I noticed even after tightening the bolt that the blade is still wobbly. What am I doing wrong? Much appreciated if you can help.

[@TheHonestCarpenter]

Hmm...I’m worried your mounting bolt might not be going all the way in 🤔 Might want to write the manufacturer

[@magicharry17]

The inner washer on my saw fell off and I noticed it had a raised side and a flat/slightly recessed side. Which side goes up against the blade?

[@TheHonestCarpenter]

Hey magicharry17, it's hard to say without seeing. If the raised side slides into the arbor hole on the saw blade, then it probably gets oriented that way. My makita has something sort of similar

[@TheHonestCarpenter]

What's your brand?

[@magicharry17]

@@TheHonestCarpenter It's a makita

[@magicharry17]

@@TheHonestCarpenter 5007MG

[@TheHonestCarpenter]

@@magicharry17 Gotcha. That's a great saw (Makita just makes the best circular saws in my opinion). I actually went out and checked mine--it's an older model obviously, but I saw the flat and raised parts of the inner washer. I had the raised part facing in, but I actually just changed it to face out because the recessed side seemed to fit better that way. You may want to consult a manual or even write Makita, but for what it's worth, I've cut about a million board feet with it the other way and it's never fussed. I'd be inclined to thing the tool is pretty tolerant either way so long as the outer washer and nut are tight.

[@TheHonestCarpenter]

Hey Tice, I haven’t handled the black and decker, but I have felt juuust a little arbor slack on a lot of circular saws. As long as it’s the whole mechanism moving, and not just the blade sliding around, then it may not be too bad. Just handle carefully!

[@lblasso]

Why does the saw rotate counter clockwise? Don’t you want the chips to fall on the floor.

[@jobacuda4472]

Lynn, if the blade rotated in the opposite direction, it would pull the saw forward aggressively. Always wear safety glasses when cutting anything.
