Many problems tend to occur in the last 20% of the borehole depth. Brenner points out that this is due to the difficulty in chip evacuation as the hole deepens. The exact solution varies depending on the condition of the workpiece and material. The application engineer should determine the step-by-step cutting plan on a case-by-case basis.
When it comes to micro-drills for processing circuit boards, although the material and diameter of the drill bits are very similar to micro-drills designed for processing ductile materials, the cutting geometric parameters of the two are quite different.
