The Synthes 310.28 drill bit is a precision twist drill designed for small bone and mini‑fragment orthopedic and maxillofacial applications. Its 2.7 mm diameter makes it suitable for drilling “gliding holes” (i.e., holes that allow a screw to pass freely rather than threads‑engaging) in cortical bone when using 2.7 mm cortex or lag screws. The relatively slender profile helps minimize disruption to bone and surrounding tissue, useful in delicate or constrained areas.

One of its key features is the quick coupling (quick connect) interface. This allows the drill bit to be rapidly attached and detached from compatible drill drivers or powered handles. In an operating theatre environment, this speeds up instrument changes, improves workflow efficiency, and reduces time under anesthesia. The 125 mm total length (with ~100 mm functional shaft in some variants) gives sufficient reach for many surgical sites, especially in small or mid‑sized bones. It balances reach with control—long enough to reach deeper anatomical locations but not so long as to become unwieldy.

Clinically, the 310.28 is used when drilling pilot or gliding holes for screws in small bone reconstructions, fracture fixation, or for lesser trochanteric and metaphyseal areas where precise alignment and minimal bone removal are crucial. Because of its fine diameter and surgical steel construction, it must be sharp and well‑maintained to reduce torque required and avoid heat generation. Sterilization between uses is essential. Also, the quick connect design demands that compatible handles and power tools are used correctly to avoid slippage or “wobble,” which could impair accuracy or harm tissue.
