Default Chipped teeth on saw blades, cutting aluminum...

The missing/chipped teeth mean you have hit a nail or something really
hard. Aluminum did NOT do it. If these are quality blades, take them to
a commercial saw blade sharpening service. They will replace missing teeth
and advise on whether the blade is worth messing with.


Proly not for a $15 blade. There is a place that resharpens non-carbide
cold-saw blades, and that charge is minimum $30.

Can a DIYer braze carbide? How is it done commercially? Plain ole brazing
rod?


I suspect the Morse blade you mention is made for cutting steel, not
aluminum (though, it will work). Here is some information:

Well, it says "aluminum blade" right on the blade/package.
In fact, on your link, my exact blade is second from the top in that list
you see if you scroll down a bit.

So if you take Morse at their apparent word, there are design diffs for all
those applications.


Old blades make decent knife blades or you can mount battery clock
movements on them to give as gifts.


Neat ideas. I think a really beat up saw blade would make a great clock
face!!
Heh, mebbe with some dried blood on it?? LOL!!!

Maybe you know someone who
likes to paint sawblades. It hurts my soul to see a fine old London 12 or
similar with its cutesy snow scene.

Awl --

I do some alum cutting on my RAS, using mostly 60 tooth 10" blades --
everything from 1/8" material, to 3" material, with 1" flat and round bar
being typical.

How significant is chipped/missing carbide on a tooth or two
(non-adjacent)?

If a chipped/missing tooth is ok for 60 tooth, how coarse can the blade
get before missing/chipped carbide is not OK?

If dicey on alum, can these chipped blades be used safely on wood?

I will switch to new or unchipped blades awaiting Group Advice.

Also, I have a 10" 80 tooth Morse Metal Devil specifically for alum,
which doesn't look much different than other non-specific 60 tooth
carbide blades -- except the price sticker, $90 !! It was given to me.

I just bought an Avanti two-pack of 10" 60 tooth from HD, for $29. Just
wondering what diffs between the two blades to expect, if any.

Any nifty uses for worn-out RAS blades? Frisbee?? Just scrap'em?
