Explanations for friction drilling:

Friction drilling is a method of making holes in metal in which the material is pushed out of the way with the aid of heat from friction. The process is also called thermal drilling, flow drilling, form drilling, or friction stir drilling. Friction drilling is commonly used to create holes for strong mounting or connection.

Advantages:

1. Very quick process (2 to 6 seconds)

2. The process reshapes all material so that no material is lost. The excess material forms a sleeve that is about 3 times longer than the original thickness of the target material, which makes it possible to make very strong bolt joints in thin material.

3. It is a clean process because no litter (particles) is produced.

4. No access needed to back of workpiece, as with press-in or self-clinching hardware.

5. More reliable and faster than rivet nuts (an alternative that also does not require access to back of workpiece).

6. Works in almost all kinds of metal.
