Undercutting is some of the toughest work on the railroad. Heavy ballast, compacted rock, and nonstop grinding quickly destroy standard wear parts — slowing production and sending crews back for change-outs.
BTI undercutter wear parts are engineered for these conditions. Every bar, chain, and plate is protected with solid tungsten carbide to resist abrasion, impact, and continuous loading under the ballast deck.
From Plasser RM-series units to other leading undercutter platforms, BTI provides carbide-protected bars, chains, and replacement components designed to withstand abrasive rail conditions. Browse our commonly supplied models and components—and reach out if you need something unique or custom.
