In the aircraft factory next door to my shop they use a miter saw for
cutting aluminum. One of the new guys tried chopping some chrome moly
steel tubing with it and stripped off all 80 teeth. I got a look at
the remains of the blade and a handful of the teeth; and saw that all
of the breaks were in the steel disk - the carbide teeth (and the
carbide-to-steel bonds) were undamaged. The teeth were still sharp and
none that I saw were chipped.
Solid carbide router bits bear a remarkable resemblence to the carbide
end mills commonly used to machine steel, brass, aluminum, etc (the
most common configuration is a spiral up-cut) and I regularly buy end
mills for use in my CNC router because they're often less expensive
and are available in more sizes than router bits.
