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.

Patent Pending

A Fit System That Is One-of-a-Kind

The SITEH3RO™ holder is the only quick-release interface engineered specifically to transfer the full torque of a modern impact wrench into cutting tools. International patent pending (WO2024/100390). Nobody else makes this connection — which is why no other cutting-tool system turns an impact wrench into a full-range metalworking machine.

One-Handed Release

Swap Tools in Seconds, Not Minutes

The quick-release mechanism lets you change cutting tools with one hand — no chuck keys, no fumbling. Drops onto your impact wrench and stays locked under full torque. One SITEH3RO™ holder in your tool belt, any SITEH3RO™ cutting tool you own in the other pocket, and you are set for drilling, reaming, threading, or expanding on site.

PTIA 2025 Winner

Designed by Unibor. Made for Metal.

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.

The SITEH3RO™ holder is the missing link between your impact wrench and the SITEH3RO™ tool range. Quick-release design locks on in seconds and releases one-handed. Unique universal grip accepts tools from any angle — no fiddling with chucks or keys. Available for 1/2" and 3/4" square drive impact wrenches.
