- Metal cutting
- Steel studs
- Emt conduit
- Angle iron
A 7-1/4 in. 48-tooth TCG Steel Demon blade for cutting ferrous metal (steel studs, EMT, angle iron, bar) on a circular saw with far less spark than an abrasive disc, leaving a cool, burr-free edge. It outlasts cut-off wheels. It's ferrous-only, the 0.087 in. kerf needs a slow feed or teeth chip, and it's wasted on wood.
Pros
- TCG carbide cuts steel studs, EMT, angle iron, and bar with far less spark than an abrasive disc
- Leaves a burr-free, cool cut you can handle almost immediately, unlike a cut-off wheel
- Lasts many times longer than abrasive discs and doesn't shrink in diameter as it wears
Cons
- Ferrous-only; it is not for stainless, aluminum, or non-metals
- Thicker 0.087 in kerf and metal cutting demand a slow, steady feed or teeth chip
- Costs several times a wood blade and is wasted if used on lumber
