The hole
When hand drilling aerospace components the following characteristics are critical: 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.
The machine
Hand drilling is unlike CNC, robotic and semiautomatic drilling in that the hole location, approach angle and feed are controlled by the operator. Always consider
Coolant
Coolant supply influences 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.
