What Is Gundrilling & Why You Need It!

The gundrill tool is a toughened tube, swaged into a kidney shaped profile with a tungsten carbide, kidney shaped tip. The tip will then have one or two coolant holes dependant on the diameter of the drill tip. The outer edge of the gundrill tip makes the initial cut which then loads the bearing pads, forcing them into the wall of the bore creating a burnished, and sometimes, a mirror finish Gun Drill Help!!! · So we order an Eldorado single flute carbide gun drill in a hope to fix this problem.
