The DeHoff G560-DR2 performs both gundrilling and reaming operations on gun barrels.
After the barrels are gundrilled, 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 inches (1524 mm).
The G560-DR2 is part of a turnkey package of gun barrel manufacturing equipment offered by DeHoff, including machines for gundrilling, pull-reaming, button rifling, cut rifling, as well as tooling, heat treat ovens, and gaging equipment.
All 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 superior vibration damping, extended tool life, and improved surface finish.
