True or False: A drill guide is not necessary when enlarging holes in composite material.

When working with composite materials, using a drill guide is essential when enlarging holes to ensure precision and avoid potential damage to the material. Composite materials can be sensitive to drilling techniques; without the proper guidance, there is a higher risk of delamination or producing an inaccurate hole. A drill guide helps to stabilize the drill bit and maintain alignment, resulting in cleaner, more accurately sized holes, which is critical in aerospace applications where tolerances are stringent and structural integrity is paramount.

While there may be scenarios where a less rigid setup may suffice, depending on the techniques and tools used, it is generally advisable to use a drill guide for enlarging holes in composite materials regardless of hole size. This approach minimizes errors and ensures the desired finish and performance characteristics of the composite are retained.
