Reliable Support
We pride ourselves on providing outstanding customer support. Whether you need assistance with setup, troubleshooting, or expert advice, we are here for you every step of the way.


The Heart of the Machine
Made from induction hardened, chrome plated, precision ground, and polished steel, our bars are included in our Line Boring Sets and have square tool ports broached every 2.5 – 3 inches so that you can measure without pulling the shaft out. Use a Starrett 823 inside micrometer.
What Sets Our Line Boring Kits Apart
Line boring projects demand both meticulous precision and reliability. With our custom machining system, you get the expertise and quality needed to keep your equipment performing at its peak.
