Hilti DD-WFI Flow Indicator

Description

The Hilti DD-WFI is a flow indicator from Hilti’s diamond drilling system, used to monitor the water supply reaching the core bit during wet coring operations.

In diamond core drilling, a steady flow of cooling water is essential for bit life, dust suppression, and hole quality. Mounted in the water line, the DD-WFI lets operators visually confirm flow while drilling through reinforced concrete, masonry, or stone, so blockages or supply problems are spotted before they damage the tooling.

This unit is used and has been tested in our workshop before listing. Cosmetic wear consistent with prior service may be present. Every order is backed by our 30-day DOA replacement guarantee and ships worldwide with tracking in secure packaging.
