Precision Cutting Performance：Bi-metal reciprocating saw blades feature a reinforced cobalt edge for seamless cutting through sheet metal (0.1-0.3"/2-8mm), pipes, and structural profiles up to 7" diameter. Ideal for medium-to-heavy gauge metal applications with reduced blade deflection. Optimized Heat Dissipation Technology：The 0.9mm thin-wall design with staggered tooth geometry minimizes friction and thermal buildup during prolonged heavy-duty cutting operations, ensuring sustained cutting efficiency and blade integrity. High-Velocity Demolition Cutting：14 TPI high-density tooth configuration delivers 30% faster cutting speeds compared to conventional bi-metal blades while maintaining extended service life in demanding demolition scenarios. Cobalt-Enhanced Durability：Manufactured with premium bi-metal steel containing 8% cobalt reinforcement, these blades provide superior wear resistance and fracture prevention during thick/heavy metal cutting, significantly reducing blade failure risks. Universal Tool Compatibility：1/2" shank design ensures full compatibility with all major reciprocating saw brands.Certified for professional-grade power tool integration.
