Twist Drill 4.0mm

Clinical Application

This twist drill is designed for controlled bone penetration and pilot hole creation during orthopedic, trauma, spine, maxillofacial and other procedures requiring precise bone preparation. The 4.0 mm diameter is intended for creation of mid-sized pilot or clearance holes used when placing fixation hardware or preparing sites for implants. Surgeons rely on twist drills to establish accurate trajectories prior to tapping or screw insertion and to remove bone efficiently with minimal thermal damage when used with appropriate technique and irrigation.

Design & Configuration

The straight, twist-fluted geometry provides a balance of cutting efficiency and effective evacuation of bone chips from the hole, reducing clogging and torque spikes. A well-formed multi-flute cutting tip promotes rapid entry and centering on bone while maintaining tactile feedback for the surgeon. The 4.0 mm diameter yields predictable hole sizing for mid-range fixation tasks; diameter selection affects screw purchase and cortical/cancellous engagement, so matching drill size to clinical indication is important.
