Updated Operator Control Panel for Eldorado Gundrilling Machines
Every new Eldorado gundrilling machine now features an updated operator control panel. While still using a PC-based system featuring Beckhoff controls, both the hardware and software have been improved with job shop operators in mind.
DeHoff 1536T Gundrilling Machine
The DeHoff 1536T is a gundrilling machine used to manufacture high-performance military helicopters. Several of the helicopter’s drivetrain components are gundrilled to produce hollow centers, which reduces mass while maintaining high rotational rigidity.
DeHoff 1024C 6-Spindle Gundrilling Machine
The DeHoff 1024C is a 6-spindle gundrilling machine used for high-volume production of automotive camshafts. The machine is designed to gundrill a hole down the centerline of the camshaft to reduce weight. This enables a Tier 1 automotive supplier to produce lighter camshafts in large volumes for use in new high-efficiency engines.
Eldorado M75-48T Two-Spindle Gundrilling Machine
The Eldorado M75-48T is a two-spindle gundrilling machine with 48 inches (1,219 mm) of slide travel. This is 60 percent more slide travel than the standard Eldorado model offered by the company. The additional length allows the machine to accommodate nearly all the gundrilling applications a job shop will encounter.

Eldorado M75-30T Twin-Spindle Gundrilling Machine
The Eldorado M75-30T is a twin-spindle gundrilling machine with a redesigned counter-rotation fixture. To maximize the effectiveness of the gundrilling operation, it is ideal for the workpiece to be rotated in the opposite direction of the drill rotation. This improves the straightness of the drilled hole and reduces drill drift.
DeHoff 518 Cell Gundrilling Machine
The DeHoff 518 Cell is a gundrilling machine for high-volume production of scroll compressor drive shafts. The shaft requires a different diameter hole to be drilled in each end for lubrication of the scroll bearing.
DeHoff G560-DR2 Machine
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.
Eldorado KM75-48 3-axis Gundrilling Machine
The Eldorado KM75-48 is a 3-axis gundrilling machine used to manufacture products like transmission shafts, manifolds and mold matrices. The machine includes updated Beckhoff controls with G-code programming, which provides enhanced flexibility.
DeHoff BTA/STS 2084 Drilling Machine
