Gun Barrel Drilling and Reaming on One Machine

The DeHoff G560-DR2 performs both gun drilling and reaming operations on gun barrels. After the barrels are gun drilled, a quick tooling changeover allows a pull-reaming operation to be performed using the same machine. The twin-spindle machine has a drilling capacity of 17 to 50 caliber and a slide travel of 60" (1,524 mm).

The G560-DR2 is part of a turn-key package of gun barrel manufacturing equipment offered by DeHoff, including machines for gun drilling, pull-reaming, button rifling, cut rifling, as well as tooling, heat treat ovens and gauging equipment.

DeHoff machines are made in the USA and feature a cast iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs and straps (versus linear guide ways and milled surfaces). This results in enhanced vibration damping, extended tool life and improved surface finish.
