Most drilling challenges are measured in meters. This one was measured in millimeters. When a customer required a hammer with an exact 123 mm outer diameter, KOVAI was tasked with delivering a solution where precision was non-negotiable. The result demonstrated how a seemingly small specification can have a significant impact in the field.
For decades, a California drilling contractor battled some of the region’s toughest granite and basalt formations. Slow penetration, excessive wear, and costly downtime had become accepted challenges—until a new hammer entered the field. What happened next delivered results that surprised even a team with over 36 years of drilling experience.
Kovai Drilling Applications is pleased to announce the launch of its new range of Down-The-Hole (DTH) Drill Pipes, marking another significant milestone in the company’s journey toward delivering comprehensive drilling solutions for the mining, quarrying, water well, and geotechnical industries.
Kovai Drilling Applications continues to expand its footprint in the North American drilling market with the introduction of its KH650R series, a redesigned line of 6-inch Down-The-Hole (DTH) hammers purpose-built for drill-and-blast applications in aggregates and mining.
