The SITEH3RO™ Difference

Engineered for Professionals. Exclusive by Design.

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.

World-Exclusive

A Coating No Competitor Has

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.

Patent Pending

Runs on the Tool Already in Your Hand

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).
