At the core of the KH650R is a redesigned long-stroke piston engineered to deliver greater impact energy per blow. The result is faster penetration rates across a range of rock conditions, helping contractors reduce cycle times and increase overall productivity on aggregates and mining sites.
Key design enhancements include a heavier piston with increased surface area for more efficient energy transfer, a thicker guide tube for added durability under sustained high- impact loads, and a groove-free, reversible-wear sleeve designed to extend the hammer’s operational life between rebuilds.
The launch of the KH650R series underscores Kovai Drilling Applications’ ongoing commitment to engineering excellence and its strategy of adapting proven technology platforms to serve new applications across the mining, quarrying, water well, and geotechnical sectors.
As demand for higher-performing, lower-maintenance drilling equipment continues to grow across North America, Kovai remains focused on delivering tools that help contractors and operators achieve consistent results in the most demanding environments.
