Donson Purchases New Eldorado M75-30 Twin-spindle Gundrilling Machine

With a gundrilling diameter range of 0.039 to 0.75 inches (1.0 to 19.1 mm), Donson’s new Eldorado M75 is extremely versatile and features slide travel options up to 48 inches (1219 mm) long, allowing the machine to tackle the most challenging deep hole jobs.

The M75 also utilizes counter-rotation of the workpiece, which rotates the part in the opposite direction of the gundrill. This improves the accuracy of the gundrilling operation. Other features include a 2,500 psi (170 bar) coolant system with a Flo-Minder flow monitor to ensure consistent coolant control.
