for non-ferrous metal cutting are specially designed to reduce the

As well as having many small teeth, the front cutting edge of each tooth
slopes slightly backward to avoid digging into the soft metal (known as
"negative rake"). Also the top profile of each tooth is designed to
remove the metal as small chips.

Even negative rake blades are not jam-proof, especially when cutting
through tubing. Half-way through the cut, it becomes very easy to hook a
tooth into the wall of the tube, and BANG - it jams. Larry is very right
to be using a jig to hold everything very firmly.

I also believe in the right tool for the right job too but when I saw
the $80 USD price tag on the right blade using the wrong one became
more appealing.

We can pay those prices for big-name industrial saw blades in Europe
too. However, a 10in/254mm blade with negative rake carbide teeth can
also be found for less than $30:http://tinyurl.com/4lflw2

That's not so bad, and I'd guess that someone in the USA is selling them
too.

If anyone over here is selling them near that price I can't find them.
I may splurge a bit and get an $80 one.
A big piece of aluminum stuck between my fingers convinced me.

Commercially, we use a triple chip blade. The current blade is almost 10
years old and leaves a mirror finish on the aluminum cut.

I just realized I worked 37 hrs of overtime in the last 2 weeks. I
think I am going to treat myself to one of the triple chip blades.

Heck just across the pond in Germany they gits 4 month paid vacation
plenty of time to use a diamond fingernail file to cut that aluminum.

Hey OM
If a twin blade 6.25 inch blade cuts like a 14 inch blade what's a
triple blade cut like?

And can you shave your face with that mirror?
That would make one heck of a disco ceiling mirror ball.

Twin blade is lifetime gaurantee.

It is a single blade- and the triple chip refers to the rake of individual
teeth. I think every aluminum house uses a triple chip blade. Not cheap at
$150 or so- but as I said, one of our blades is around 10 years old, is used
daily and still cuts with a mirror finish.

For those still interested I found that Delta makes a non ferrous
blade that sells for about $25 USD.
