How To Change The Blade On A Circular Saw

Can a regular framing blade cut through solid rock? Let’s find out.
Actually, it can- I was surprised.
Ok so this blade was already dull and needs to be replaced- I thought I’d show you how to change the blade on a circular saw.
First thing you want to do is remove the battery.
Next, we need to loosen this bolt.
Most saws have a tool on them for taking off the blade- this one has an allen wrench on the side.
You’ll notice the blade just wants to spin, so we need to push the spindle lock. This holds the blade in place so you can loosen the bolt.
Here you can see it lock in- now I can finally loosen the bolt.
After the bolt is removed, raise up the guard and slide the blade out the bottom. Make sure to save the flange.
Time to pop in the new blade. You want the teeth pointing up at the front. Usually the side with the writing is on the outside.
Reinstall the flange, the bolt; then engage the spindle lock so you can tighten the bolt.
You want it snug, but don’t overtighten it.
Now I can go back to cutting rocks. @hausplans

  1. New guy napping at the time, not taking any notes how to replace the blade!!

  2. If you can’t figure out how to change the blade on a circular saw, you probably shouldn’t be using a circular saw

  3. You did it wrong, you're supposed to throw out the whole thing and get a dewalt one!

  4. I absolutely love my Milwaukee tools, but Diablo blades are the only way to go

  5. You're an all-rounder. An amazing and practical teacher, fun cook, New guy's favourite boss… And the list goes on.
    You're the best.

  6. Sweet, it'll cut through steel too, up to 1/4'' or better with milder steel. Go very slow.

  7. Another quick tip is instead of using the spindle lock you can just turn it on instead that way it won’t just spin freely
    (Hope this helps)

  8. My friend uses wood blades to cut through metal sheets and aluminium tubes
