The hole

When hand drilling aerospace components the following characteristics are critical:

  • Hole diameter
  • Exit delamination or exit burr
  • Straightness
  • Perpendicularity

Aerospace fasteners typically require their own hole tolerance. These are different than universal IT standards. Be sure to ask what the hole tolerances are before starting a test.

The component

To be successful you need to understand the entire application especially the component size, shape and material.

  • How is the component fixtured?
  • Machinability?
  • Material stacks?
  • Machine capabilities?


Coolant supply influences

  • Tool life
  • Hole quality
  • Chip evacuation

As portable hand motors do not have internal coolant, a lubrication paste is often used and recommended for stack with metallics. No lubricant is needed for CFRP only stacks.
