KDK tooling and Kelly bar adapters
Engineered Kelly Bar Solutions for Drilling & Piling
RPI Construction Equipment continues to expand its service capabilities with comprehensive Kelly bar repair, new Kelly bar fabrication, and foundation tooling maintenance for drilling and piling equipment. While we support repairs when they make sense for the customer, a growing number of projects benefit from a completely new, custom-built Kelly bar that is engineered for the exact rig setup and drilling conditions. RPI manufactures new friction, interlocking, and telescopic Kelly bars that deliver strength, alignment, and long-term reliability.
Our skilled technicians diagnose, repair, and rebuild all types of Kelly systems, including telescoping Kelly bars, boring bars, and Kelly stubs. We use advanced welding and machining techniques to ensure each repaired or custom-built component meets or exceeds factory specifications.
We stock and service a wide selection of KDK tooling and Kelly bar adapters, which support seamless integration between your existing foundation equipment and both new and refurbished components. Every build or repair is completed with close attention to engineering detail to extend the life of your equipment and reduce costly downtime.
In addition to in-shop fabrication, RPI provides mobile support and field services for heavy drilling and foundation equipment. Our team responds quickly to help keep your operation on schedule and your rigs performing at full capacity.
With a focus on quality, reliability, and expert craftsmanship, RPI Construction Equipment is a trusted source for new custom Kelly bars, precision repair, and complete tooling solutions that keep your foundation drilling projects moving forward with confidence.
