The Power Tool Industry Association 2025 Tool Innovation Award recognises tools that meaningfully change how tradespeople work.
SITEH3RO™ won for letting one operator do work that previously needed a drill press and bench setup, using the impact wrench they already own.
Powered by your impact wrench
Most taps shatter under impact-wrench torque. SITEH3RO™ taps are specifically engineered for impact-wrench drive. No drill press required, no bench vise. Thread steel on the job, in place.
Fits any 1/2" or 3/4" square-drive impact wrench.
Built by people who work metal
