Crutchfield Drill Bit 3.5mm

Clinical Application

Designed for preparation of pilot holes for 3.5 mm fixation screws, this drill bit is used in procedures requiring precise trajectory control for spinal and small‑bone fixation. It is intended to create a consistent, properly sized pilot channel to improve screw purchase and reduce the risk of stripping when placing 3.5 mm implant systems.

Design & Configuration

The twist‑flute geometry provides efficient cutting and chip evacuation during drilling, helping maintain a clear view of the entry site and minimizing clogging. The straight shaft delivers axial rigidity and tactile feedback for accurate alignment with the planned screw trajectory. A cutting diameter matched to 3.5 mm screw systems ensures appropriate clearance for thread engagement while preserving bone stock.
