The Tenryu PRF-18548BW is a 7-1/4 48 Teeth Steel-Pro Series Circular Saw Blade. This steel cutting saw blade makes light work out of all kinds of mild steel steel studs, steel sheet, steel pipe, channel and threaded rod. Specially formulated C-6 carbide grade, combined with our unique tip design, resists breakage on impact and lasts longer- much longer than standard carbides or abrasive discs. Special tooth geometry with inserted tooth design greatly improves security of the tip, efficiency and durability. It cuts thick (up to 1/8) and thin ferrous metals (mild steel) faster, cleaner and easier.
