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

Our proprietary high-performance coating is exclusive to SITEH3RO™ — not licensed, not available from any other manufacturer on any other machine tap. Independently high-temperature tested to 356°F. Delivers up to 75% longer tap life than standard spiral-point taps, so you thread more holes in harder steel before chip-loading forces a replacement.

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).

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.

SITEH3RO™ spiral point machine taps thread holes up to 20× faster than hand tapping — powered by your impact wrench. The spiral point ejects chips forward for clean, first-pass threads in structural steel and plate up to 1" thick. If the tap catches, the impact action absorbs the torque — no snapped taps, no wrist injuries, no drama.
