Twist Drill 3.5mm

Clinical Application

This 3.5 mm twist drill is used to create precise pilot holes for 3.5 mm cortical and small-fragment screw fixation. Common applications include extremity fracture fixation, osteosynthesis in hand and wrist surgery, foot and ankle procedures, and trauma cases where accuracy of screw trajectory and diameter is essential. Proper pilot-hole preparation with a matched-diameter drill improves screw purchase, reduces the risk of cortical splitting, and aids in accurate plate and screw placement.

Design & Configuration

The straight, fluted twist geometry provides efficient cutting action and controlled chip evacuation during bone drilling. The helical flutes and cutting lips are configured to balance cutting efficiency with torque control, enabling smooth penetration of cortical and cancellous bone while minimizing chatter. A consistent 3.5 mm cutting diameter ensures predictable fit for 3.5 mm cores and facilitates reproducible screw insertion trajectories, which is critical in fragment alignment and fixation accuracy.
