PTIA 2025 Tool Innovation Award
The Professional Tool & Industrial Alliance recognized the SITEH3RO™ system with its 2025 Tool Innovation Award.
The award recognizes tools that materially change how a job gets done on site. The SITEH3RO™ system was selected for letting tradespeople do bench-quality drilling, reaming and threading using only the impact wrench they already carry.
