International Revere Machining Introduces Improved Portable Line Boring Sets to Support Industries Nation-Wide
International Revere Machining (IRM) is announcing the launch of its improved line boring sets, designed to perform on-site and facilitate efficient repair of worn-out holes in a variety of machinery, all in a cost-effective, portable solution. This innovative product line reflects IRM's commitment to quality and precision in an ever-evolving manufacturing landscape.
Led by Anguel Bojinov, who immigrated from Bulgaria in the 1990s, the family-owned business has become a cornerstone of the city's machining community, known for its expertise in repairing elevators of iconic buildings and creating custom parts.
With the introduction of their improved line boring sets, IRM is enhancing its service offerings to better support businesses nation-wide. Line boring is a precise machining process used to repair or refine the diameter of a hole, ensuring exact alignment and uniformity—an essential requirement for fitting parts like bushings and bearings in heavy machinery. This technique is crucial for repairing worn components, extending equipment life, and maintaining the functionality of previously worn-out machinery.

The line boring sets include high-quality tensile boring bars crafted from induction-hardened, chrome-plated, precision-ground, and polished steel. Each bar features square tool ports broached every 2.5 to 3 inches, facilitating accurate measurements without the need to remove the shaft. For added precision, machinists can conveniently utilize a Starrett 823 inside micrometer.
Additionally, the innovative power feed assembly, designed and manufactured by International Revere Machining, offers a smooth cutting experience, ensuring consistent results. This design accommodates various motors, including drills that users may already have or options available from IRM’s selection. The adaptability to different shaft-driven motors, such as Milwaukee magnetic drills and mixer motors, further enhances the versatility of these sets.
To ensure seamless integration and effective use of the line boring sets, IRM offers comprehensive on-site training tailored to meet the specific needs of each client. Our experienced team provides support through various channels, including FaceTime, Zoom, text, or email, allowing clients to reach out with questions at any time. This commitment to accessibility ensures that our customers can confidently utilize their new tools and maximize their investment.

With these portable line boring sets, businesses can find the reliability and efficiency needed to keep their operations running smoothly, empowering them to tackle even the toughest machining challenges with confidence.
