Upgraded heat treatment (quenching process) to increase hardness and wear resistance for heavy-duty concrete drilling
Extended 340mm overall length for longer reach and enhanced drilling depth versus typical 13-inch (330mm) bits
Cross-tip carbide head for faster penetration, cleaner holes, and smoother operation with reduced vibration and wear
Forged high-strength alloy steel construction for toughness and impact resistance on demanding jobsites
Designed by a manufacturer with 20+ years of tool manufacturing experience
Best for: DIYers and pros who need a 1/2″ SDS-Max bit with extra reach for masonry drilling projects where standard-length bits come up short.
