As a small family business, we understand the need for reliable, cost-efficient equipment. Rather than spending money on replacing heavy equipment or paying someone else to fix it, fix it yourself with our portable Line Boring Sets!

Ultimate Flexibility for Repair Jobs

Use our line boring sets to repair: Gearbox parts and housing, farming equipment, valves, clevis plate bores, driveshaft housings, elevator sheave housings and motors, construction equipment and buckets, shipbuilding components, and more.

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.

Customer reviews

“We were lucky to find International Revere Machining when we were searching for a line bore system. We knew little about line bores and were struggling finding a setup that fits our need. After a conversation with Angel we were more than confident that we had found the right guy. His system is simple, economical and works great! Angel worked with us for months to design custom fixtures for our specific application. This combined with his power feed made a final product that is fast, and efficient and has a great end result. The support that comes along with Angel's system was invaluable, if I have a questions or a problem I know that I can call, or if I need any replacement parts I can get them the same day. Not 2 months away from Hong Kong. I would highly recommend IRM products!!”

“International Revere Machining has been providing my company with exceptional service for over 8 years. Throughout this time, Anguel has proven to be a master engineer! Whether repairing old equipment, or machining replacement parts, he has the passion and skills to keep our equipment running! We are grateful to have you as a supplier.”

“We have been working with Angelo and International Revere Machining for 15+ years and have nothing but wonderful thing to say about them. The work they do is meticulous. When we have a breakdown and need expedited service, I know I can always rely on them. From quality workmanship to friendly service, I would recommend them to anyone.”

“Been using International Revere for my machining needs for over 20 years always accurate and always on time.”

“This wife-and-husband pair are great to work with. They are nice, smart, and they consider your machine problem to be their machine problem. I found myself wishing that something else would go wrong so I could bring it in to them.”

“I had a single item project for my boat that I brought in for them to work on. They were very friendly and helpful. I have no hesitation recommending them.”

“Anguel is a wizard! He remanufactured a rare and expensive supercharger bracket for me the same day I brought it in. This helped get my car back on the road in 1 day instead of the 14 that Honda needed to ship me the part. The machining is perfect and he even coated it to prevent rust for me. Incredible service and customer support.”
