The DeHoff 3060 is a single-axis boring machine used in the railroad manufacturing supply chain. The machine is custom designed for boring the bottom housing of a rail car hopper bin.

The DeHoff 3060 has a single spindle with a maximum boring capacity of 3 inches (76.2 mm) and a maximum boring depth of 60 inches (1524 mm). To meet the rigorous material removal requirements, the cutting tool is powered by a 40 horsepower spindle motor with a 4-speed gearbox. A totally custom workpiece loading and fixturing system was designed specifically for the customer's unique part. The machine features Beckhoff CNC controls with G-Code programming capability.

DeHoff machines feature steel box ways and hand-scraped mating components (instead of cheaper linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved surface finish. DeHoff deep hole drilling and boring machines are designed and manufactured by Kays Engineering in Marshall, Missouri, USA.
