The Drill Guide

Preferable for large-diameter drilling, often used in aerospace and heavy industry.

As depth increases, so does temperature. Lubrication is essential to reduce friction between guide pads and the workpiece. The Drill

Ideal for small-diameter deep holes, typically producing highly precise, straight holes. Preferable for large-diameter drilling

Future technologies include pulse plasma drilling—using electrical discharges to disintegrate rock—and gyrotron-based millimeter-wave beams that melt through rock. Scientific and Industrial Significance typically producing highly precise
