Not used them myself but the ti coated bi metal blades are supposed to go through nails. E.g. https://www.dewalt.co.uk/products/dt20747-qz--64mm-titanium-bi-metal-wood-with-nails-saw-blade
I would still take it slowly even with one of them and quench.
Carbide would be better but more expensive.
Thanks. Longer life that the bi-metal ones may equate to more than two screws albeit I think I wasn’t using the blade correctly - too fast and too hot for optimal performance.
