Morphology
The compound is compositionally built: 'pilot' (to guide or act as a guide) combined with 'bit' (the cutting part of a drill) yields a bit that guides or creates a starter hole. This noun+noun attributive pattern is regular and the technical meaning ('starter/guide drill bit') is directly inferable from the constituents, so a B1 learner who knows both words should understand it.
Etymology
Pilot bit comes from the idea of a small pilot as a guide and bit as a drill tip that first makes a tiny 'starter hole' to 'guide' a larger drill. So, it means a small drill piece used to start a hole and keep the main drill in the right place.
