What precaution should be taken before starting to drill in composite material?

Before starting to drill in composite material, ensuring that the drill bit is sharp is crucial for several reasons. A sharp drill bit is essential because it reduces the amount of force required to cut through the material, which helps prevent damage to the composite. Dull bits can create excessive heat and friction that may lead to delamination, fraying, or other structural issues in the composite layers. A sharp drill bit also helps maintain accuracy and produces cleaner, smoother holes, which are important for the integrity of the assembly.

While checking assembly alignment and setting the drill to low speed are important considerations when working with composites, the primary focus before initiating a drilling operation should be the condition of the drill bit itself. A sharp bit directly influences the quality of the drilling process, making it a critical first step.
