Circular saw blades
for non-ferrous metal cutting are specially designed to reduce the
dangers of jammed blades and flying metal.

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:

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