What is the life span of drill bits when used in composite materials?

The lifespan of drill bits when used in composite materials is generally considered very short due to the unique challenges presented by these materials. Composites are often made of various resins and fibers, which can be abrasive and can cause rapid wear on tools. The drilling process can produce high temperatures and pressure, leading to tool degradation more quickly than in metals or other materials.

Drill bits can become dull, chipped, or damaged more rapidly when used on composites, requiring more frequent replacements. Additionally, the specific properties of the composite—such as fiber orientation and matrix type—can further influence the rate of tool wear. Therefore, the characterization of drill bit lifespan in this context as "very short" accurately reflects the short operational effectiveness of the tools when working with composite materials, necessitating frequent monitoring and potential replacement.
