A complete SITEH3RO™ spiral point tap set — thread holes up to 20× faster than hand tapping, powered by the impact wrench you already own.
Designed by Unibor for tradespeople who value tools that last and outperform. Every SITEH3RO™ product is engineered around three things you won't find together anywhere else.
Every cutting tool in this kit carries the proprietary SITEH3RO™ coating — exclusive to us, not available from any other manufacturer. Independently high-temperature tested to 356°F. Delivers up to 75% longer tool life across the whole system, which means more jobs per tool and faster payback on the kit.
The SITEH3RO™ shank system is the only metalworking cutting-tool interface engineered to harness the full power of a modern impact wrench. Connect from any angle, lock in seconds, and turn a $200 impact driver into a full-range metalworking machine. No chucks, no adaptors, no slippage. Patent pending (WO2024/100390).
Designed by Unibor — a metalworking tool specialist based in Lombard, Illinois, and winner of the PTIA 2025 Tool Innovation Award. Every SITEH3RO™ product is engineered by people who've worked metal for decades, to the standards real tradespeople set.
