HARDWIN 7-1/4in 48T Cermet Metal Blade
This HARDWIN 48T cermet blade is built for fast, cool cuts in steel. The cermet teeth resist heat far better than standard carbide. That means fewer sparks, less burring, and a longer life. If you cut sheet metal or thin-wall tube with a 7-1/4 inch saw, it hits the sweet spot of speed and finish.

It should cut cool, stay sharp, and track straight. Cermet or TCT teeth help. A TCG tooth profile controls grab. Good plates reduce vibration and burrs.

Yes, with care. Use fine-tooth or cermet blades, a steady feed, and light lube. Avoid forcing the cut. Too much heat can dull teeth fast.
