The only non-ferrous blade here — and it says so

TOMAX TMA10801, 10 in 80T TCG, 5/8 in arbor

A triple-chip-ground blade for aluminum and plastic, and the only blade in this hub that states what it must not be used on.

TOMAX 10 inch 80 tooth TCG circular saw blade for non-ferrous metal

  • A triple chip grind, which is the tooth form non-ferrous metal needs rather than a general ATB blade
  • Eighty teeth on a 10 in blade — a fine pitch, which is what thin aluminum section wants
  • Will not cut steel, which is most of what this site is about

Best for: Aluminum section and plastic on a mitre or table saw, where a steel blade would grab

This is the only blade in this hub for metal that is not steel, and it is honest about it from the first bullet: aluminum, non-ferrous metals, plastic. That limitation is the specification.

The tooth form is why. A triple chip grind alternates a trapezoidal tooth, which takes a chamfered roughing cut, with a flat tooth that squares the corners — so the blade shaves the metal instead of biting it. On aluminum that matters more than anywhere else: a conventional sharp-topped tooth will climb into soft metal and snatch the workpiece, and eighty teeth on a 10 in blade keeps each bite small enough to stay controlled through thin extrusion.

The arbor is published at 5/8 in, which is more than the other circular blade on this shelf manages, and the electrophoretic coating is a sensible detail on a blade that gets used with cutting wax and left in a damp workshop. What is missing is the kerf, the plate thickness, the hook angle and the maximum speed — four figures that between them decide how a circular blade behaves. And this blade is useless for the steel most of this site is about: the carbide grade and the geometry for ferrous work are different, and the Milwaukee blade on this shelf is that tool.

The questions welders ask

What is a TCG grind and why does aluminum need it?

Triple chip grind: the teeth alternate between a trapezoidal tooth that takes a rough chamfered cut and a flat tooth that cleans the corners. It matters on non-ferrous metal and plastic because a conventional alternate-top-bevel tooth is sharp and grabby, and aluminum is soft enough to climb the tooth and snatch the work out of your hands. A TCG tooth shaves rather than bites, which is why every proper aluminum blade uses one.

Why can it not cut steel?

Tooth geometry and feed rate, not hardness. A blade ground for aluminum is designed to take a small, shaving chip at high surface speed; steel needs a tougher carbide grade, a different hook angle and a far lower speed, or the teeth overheat and the tips crack off. Milwaukee’s ferrous blade on this shelf is the other kind — cobalt-infused carbide at 30 teeth on 5-3/8 in — and the two are not interchangeable in either direction.
