What tool is used to secure two pieces of material during the drilling of pilot holes?

The use of Clecos during the drilling of pilot holes is vital because they are specifically designed to hold two or more pieces of material together securely. Clecos function as temporary fasteners that can be quickly inserted and removed without causing damage to the workpieces, allowing for easy repositioning as necessary. This capability ensures that the pieces remain aligned accurately as the drilling takes place, which is crucial for maintaining precision in aerospace assembly.

While clamps can also secure materials, they may not provide the same level of accessibility and may obstruct the drilling area. Tape could help hold materials together, but it lacks the mechanical strength and stability required during the drilling process. Weights, on the other hand, do not provide a reliable method for securing two pieces together, as they can easily shift and do not guarantee a proper alignment. Therefore, Clecos are the preferred tool in this context, thanks to their effectiveness in maintaining alignment and stability during drilling operations.
