Loose Teeth In Table Saw Blade

[Quarry Man]

Building my Semi/Deep V out of 1/8" 6061 Aluminum Angle. Purchased a 10" Diablo Saw Blade (https://www.amazon.com/Freud-D1084L-10-Inch-Diameter-8-Inch/dp/B001TH8HK8). Cut the aluminum really well for about 20 cuts. Then, I noticed that like 4 cuts in a row were jacked up. Upon closer inspection, I noticed several missing teeth, about 10 of them. I don't want to risk injury at all. I was planning on bringing it back to Home Depot and getting a new blade. With the recent mandated closure of Home Depot, I don't think ill be able to. Looks like i'll have to order one online. 

 

Is it safe to keep using the blade with missing teeth? What could have caused this?

Retired Contractor/Carpenter...I would Not continue to use that blade. Also, there are better brand blades out there. I don't have any 10" blades, or I'd send ya one..Can't you order another online..?

 

Edit: I just looked at HD site. In 10" I'd recommend either the DeWalt, or Makita blades, they cost more, and for good reason

That is their bottom line blade.  They have an industrial line that is way better.  It is carried on Amazon and costs more.  I use one of the industrial blades for cutting acrylic and its great.  They do repair blades but on cheap ones their disposable.

I've used tons of diablo blades. I'm assuming the carbide tips are what's loosening on yours, probably due to cutting aluminum.

Try the freud, or irwin makes a decent more affordable one.

I don't even bother using toothed blades when cutting any metal - even aluminum. I got a couple of these for my 10" table-saw.

 

Cheap, makes a clean cut - only downside is having to change blades when I go from metal to wood.

I would never use a table saw with a damaged blade. If you're not careful those are death machines.

 

I grew up using hand tools and power tools and I tinker and build furniture pieces now and then. But the one tool that really keeps me on my toes is my table saw. I don't get cute or take any shortcuts with it and it can still scare the crap out of me on occasion.

No kidding. I'm a carpenter and the table saw keeps you on your toes for sure.

Never ever use a damaged blade. Especially in a table saw.

Good God I had some horrible visions as I clicked this thread....

I’d try MNFISHER’S idea.  I bought 900’ of 3 1/2” steel pipe and cut into 7’ lengths for posts with that type of blade and a chop saw from Harbor Freight.

Place I worked, we were always cutting steel pipe to custom lengths for the machines we were building. Cutting disk on chop-saw was the way we did it. That's where I got the idea.

That for me too... and the router, lol

 

To the subject, ain’t no way I’d use a blade with missing teeth. Hand me the hacksaw

I wouldn't use the saw with a damaged blade. I've worked with table saws for 30 yrs. Two tools I've seen guys get hurt with. Table saws and routers. Play it safe

Not saying anything that hasn't already been said (really) but missing teeth (especially many in a row) can cause the blade to then bite too heavily and unevenly into the the stock and do unpleasant things.  Definitely DON'T continue using it.

ive since swapped the blade out. luckily Home Depot is an essential business and remains open. I have had issues with the angle being projected when I am cutting a 1.5" section off as my support pieces that attach to the hull, which then attach to longer pieces. I just can't find a way to clamp it down and they go flying.
