Easily Repair & Maintain Heavy Equipment Bores

Bore Welders

For a high level of durability, ease of use, and precise weld buildup, the BOA-408i automatic bore welding system is an affordable answer. Already own a boring bar system and want to add automatic bore welding? Interface kits are provided for seamless integration. For a more compact design that’s equally durable and user friendly, there’s the BOA-M1, and if you regularly weld at high amperages for long stretches of time, ask about the BOA-550HD auto bore welder.

Line Boring Systems

There are 4 different systems available, all of which are among the most affordable and user-friendly you’ll find on the market. The BOA-C45, BB6, and AM4 line bore systems feature premium pass-thru drives, a wide diameter range, dual tool ports for easy measuring, and quick-change feed screws. Only doing a few bore repairs per year? Ask about our LT versions or the ultra-affordable 150 series end-drive boring bar.

With 7 different turnkey weld + bore packages offered, you’ll have no trouble outfitting your shop with a durable, precise, and integrated system that meets the full range of bore repair requirements.

"We absolutely love our BOA system. It has saved us tons of time on our mining and construction equipment bore repairs. It's an excellent system."

- Steve V

My BOA bore welder gives me a 90 percent time savings over hand welding, and a 75 percent machining time savings. It is quite a machine. The BOA works so well I feel like I owe Bore Repair Systems more money!
